A guide boss is provided in a diaphragm blocking the halfway portion of a channel; a valve disk is formed in the shape of a cylinder; the inner face of this cylinder-shaped valve disk is slidably engaged around the guide boss; and further, a valve port consisting of a plurality of long bores are formed in a diaphragm surrounding the guide boss. Thereby, fluid can responsively flow into the valve port when the valve disk is opened, and the follow-up of the fluid is accelerated.

A dispenser that dispenses fluid is controlled using a feedback control system. The control system uses a positional encoder to determine the precise position of a valve contained in an actuator in order to control the dispensing of the fluid. Various motion profiles may be used to control the position of the valve. The motion profiles of the valve enable controlled variation of the amount of fluid dispensed over time and enable several specific improvements to the dispensing of sealant in the manufacture of metal and composite cans.

An air outlet has at least one air supply line and at least one baffle plate, wherein the opening cross section of the air supply line is arranged in a plane running parallel to the baffle plate, the baffle plate has a circumferential contour, and is spaced apart from the air supply line, and the opening cross section of one end of the air supply line is directed toward the baffle plate. Such air outlets are particularly suited for small-volume rest rooms, such as in a vehicle, which require a sufficiently high ventilation quality at the lowest possible draught.

An apparatus for printing on cylindrical objects (31) comprises a plurality of printheads (32); and at least one holding device movable relative to the printheads (32) such that, in use, the holding device moves the object between the printheads. The path of the at least one holding device comprises a plurality of vertical sections (34) which are horizontally offset from one another. Each vertical section (34) comprises at least two identically orientated printheads (32) arranged such that they are vertically displaced from one another, with one directly above the others. The at least one holding device moves the object (31) between the at least two printheads (32) such that part or all of its path between the printheads is vertical.

In an internal combustion engine with a combustion heater for elevating a temperature of an engine related element, an object of the present invention is to provide a technique that may effectively performs temperature elevation of an exhaust gas purifying device. In order to attain this object, according to the present invention, the internal combustion engine having an exhaust gas purifying catalyst provided in an exhaust passage of the internal combustion engine, and a combustion heater comprising a combustion chamber and a heat exchange portion for transmitting to an engine related element heat held by burnt gas that has been burnt in said combustion chamber, characterized by including a first burnt gas discharging portion for discharging from the combustion heater the burnt gas which has passed through the heat exhcange portion, a second burnt gas discharging portion for discharging from the combustion heater the burnt gas which has not yet passed through the heat exchange portion, and a burnt gas passage controlling unit for supplying at least one of burnt gas discharged by the first burnt gas discharging portion and burnt gas discharged by the second burnt gas discharging portion to the exhaust gas purifying catalyst.

An injector for delivering a working fluid into a working environment is disclosed. According to one embodiment of the present invention, the injector includes a pre-metering chamber with a control valve controlling fluid delivery rate and a swirl chamber, in which a swirling flow is created and atomization is achieved at low injector pressure when it is released. In another embodiment, the injector includes a swirl chamber and an atomization element with a bore, through which a control valve is positioned. The control valve forces a working fluid flow through the atomization element when the injector is energized to create a metered swirling flow. To avoid issues with deteriorated working fluid, a purging apparatus is used for emptying working fluid residue in the injector, and a special control method is used when the injector works in a high-temperature working environment.

A method of manufacturing a laminated core includes inserting permanent magnets 14 into magnet insertion holes 12, 12a of a core body 13; injecting a resin 18 into the holes 12, 12a from resin reservoir pots 17 in the die 15 (16) to fix the magnets 14; placing a dummy plate 19 between the die 15 having the pots 17 and the body 13, the plate 19 having gate holes 35, 35a guiding the resin 18 from the pots 17 into the holes 12, 12a, the hole 35 (35a) overlapping with both of a part of the hole 12 (12a) and a surface of the body 13; poring the resin 18 via the holes 35, 35a and curing the resin 18 in the holes 12, 12a; and separating the plate 19 from the body 13 to remove the resin 18 overflowed from the holes 12, 12a.

A hydrogen generation apparatus 1 includes a raw material supply unit 4 for controlling a flow rate of a raw material to be supplied from an external element and containing hydrocarbon and an odorizing component; an odorizing component removing section 5 containing an adsorbing agent for adsorbing the odorizing component contained in the raw material; a combustor 2 for combusting the raw material; a reformer 30 for generating hydrogen-containing gas from the raw material which has passed the odorizing component removing section 5 by a reforming reaction using combustion heat supplied from the combustor 2; and a controller 16 for controlling the raw material supply unit to, during driving after the adsorbing agent or the odorizing component removing section 5 is exchanged or after the adsorbing agent is regenerated, makes the flow rate of the raw material to be supplied from the external element higher than the flow rate during the driving immediately before the exchange or regeneration.

An oil-pressure apparatus is provided with an actuating cylinder that works on the outside and an acceleration cylinder that does not work on the outside. When a rod of the actuating cylinder is extended with no load applied to the actuating cylinder, oil is supplied to the actuating cylinder through the acceleration cylinder so that extension of the rod is accelerated. When the rod of the actuating cylinder is extended with load applied to the actuating cylinder, oil is adjusted to the actuating cylinder without passing through the acceleration cylinder so that original thrust of the actuating cylinder is exerted.

A vehicle side structure of a pickup truck includes a cabin; and a loading platform that is disposed adjacent to a rear side of the cabin in the vehicle forward-rearward direction, is configured to include a bottom plate, a pair of right and left side panels, and a tail gate, and is formed in a box shape that opens toward a vehicle upper side. Each of the right and left side panels includes a traveling wind inlet part that is disposed at an outer part of each of the right and left side panels in a vehicle width direction, opens toward a vehicle front side, and includes a first opening, a traveling wind blowing part that is disposed at an upper end part of each of the right and left side panels, opens toward the vehicle upper side, and includes a second opening, and an intermediate part.

The invention relates to a method for managing an exhaust gas recirculation circuit of a petrol thermal engine, the engine including at least one combustion chamber connected to an inlet line and an exhaust line between which extends said recirculation circuit, the recirculation circuit including a flow-rate adjustment valve, wherein said method comprises the step of adjusting flow-rate adjustment valve based on a flow-rate setpoint, said method further comprising the steps of: detecting an operation parameter representative of a pressure difference between an upstream pressure and a downstream pressure relative to the flow-rate adjustment valve, and, after comparing the parameter with a threshold corresponding to a minimum pressure difference, adjusting the flow-rate in at least one of the lines in order to increase the pressure difference.
