A cooling system has a diverter valve to selectively control the flow of coolant through an internal combustion engine having a cylinder block with a cooling jacket and a cylinder head mounted on the block with a cooling jacket. A controller, responsive to the temperature of the block and the head, controls the diverter valve and a water pump to provide adequate coolant flow through the head and the block as needed to maintain optimal operating temperatures. After the engine is shut off, the controller continues to operate the water pump and a cooling fan to continue to cool the engine for a period of time.

Provided is an apparatus that includes temperature-sensitive functional means for performing pre-configured functionality (such as video recording), mounting means for mounting the apparatus to a motor vehicle, and heating means for heating the functional means. Detection means detects at least one of: whether an automobile battery in the automobile is being charged and whether an engine block in the automobile is being heated. Control means controls the heating means and initiates a heating process upon detection by the detection means.

A vehicle suspension spring system for a vehicle wheel station includes a hydraulic cylinder or strut having a piston which divides the cylinder volume into a main oil volume and an annular oil volume. The main oil volume communicates via a first oil passage with a first accumulator having a main gas volume. The annular oil volume communicates via a second oil passage with a second accumulator having an auxiliary gas volume. The oil in each accumulator is separated from the gas by a separator piston or diaphragm. A third oil passage with an isolating valve interconnects said first and second oil passages. Operation of the isolating valve is regulated by a controller. At least one sensor for sensing a parameter associated with vehicle attitude is connected to the controller. The controller is operable for switching the isolating valve between open and closed positions for altering spring stiffness of the strut in response to said sensed vehicle attitude parameter when the vehicle is in motion.

A device for aspirating and dispensing liquid samples comprising a pump that comprises a cylindrical chamber, a piston movable in this cylindrical chamber, and a piston drive that engages the piston. The device further comprises a tip connected to the cylindrical chamber with a line, and a channel system that discharges into the cylindrical chamber for flushing or rinsing the latter. The device is characterized in that the piston entirely seals this cylindrical chamber from the channel system, if the piston is positioned in the cylindrical chamber in such a way that a free piston end comes to rest between the channel system and the line. Preferably, the cylindrical chamber is located in a cylinder block, which comprises two parts that are separated by and enclosing an intermediate channel system. The channel system most preferably is implemented as a coherent cavity. According to a first embodiment, the cylindrical chamber is implemented as a sleeve that is inserted in a boring located in a cylinder block. According to a second embodiment, the cylindrical chamber is implemented as a boring located in a cylinder block. Furthermore, the invention also concerns systems with, for example, 384 or more such devices that are arranged in an array.

A response measuring device that can be used in equipment for personal training or exercise routines. This device includes a cylinder block; a chamber formed in the cylinder block and having first and second ends; a piston mounted for movement and positioned in the chamber; a detecting device mounted adjacent the first end of the chamber; and a hose having first and second ends with the first end in fluid communication with the second end of the chamber. The hose can direct a fluid into the device, with the velocity of the fluid moving the piston at least partially out of the first end of the chamber and into position for detection by the detecting device. Also, the detecting device can measure piston movement to provide data representative of user response time and amount of force applied to the sensor by the user.

A cylinder head gasket comprising a gasket plate for an engine in which at least one first coolant cavity is formed in the engine block adjacent to the cylinder head gasket, with the gasket plate comprising coolant passage openings via which the first coolant cavity is connectable to at least one second coolant cavity formed in the cylinder head of the engine; for improved cooling of the engine the cylinder head gasket comprises at least one flow conducting element for the coolant protruding from the gasket plate, the at least one flow conducting element being of such configuration and being joined to a coolant passage opening of the gasket plate in such a way that the flow conducting element forms a flow path with the coolant passage opening and is designed so as to engage in at least one of the first and second coolant cavities and to generate a directed flow of coolant at the outlet end of the flow path.

Provided is a frequency-sensitive shock absorber, which includes a cylinder filled with a working fluid and a piston rod having one end disposed inside the cylinder and the other end extending to the outside of the cylinder. The frequency-sensitive shock absorber includes a main piston valve assembly and an auxiliary piston valve assembly. The auxiliary piston valve assembly includes: a spool unit configured to open or close a communication passage for communicating a rebound chamber with a compression chamber while moving within a housing; and upper and lower support members configured to support the spool unit. The upper and lower support members have protrusions protruding toward the spool unit, respectively, and as the spool unit moves, the communication passage is closed when the protrusions of the upper and lower support members contact the spool unit.

In accordance with the invention, an internal combustion engine having reciprocating piston sleeves is realized comprising an engine block with a pair of cylinders, each cylinder having an intake port, an exhaust port and two linearly opposing pistons connected to two opposing crankshafts. A pair of piston sleeves are reciprocatingly mounted in each cylinder, one piston sleeve around each piston. Each piston sleeve is connected to one of two eccentric shafts that run parallel and adjacent to each crankshaft. The piston sleeves have ported slots in communication with either the intake ports or the exhaust ports of each cylinder. The eccentric shafts are mechanically connected to the crankshafts such that they move in unison.

The invention discloses an engine cooling system and a cooling method. The cooling system comprises a water pump, a double-valve temperature regulator, a machine oil cooler, a water jacket of a cylinder body, a water jacket of a cylinder cover, a water tank radiator and an EGR cooler. The cooling system adopts a water passage circulation as follows: when the engine is started, the water pump begins to work; cooling liquid firstly flows into the machine oil cooler and enters in the water jacket of the cylinder cover to cool the key area of the cylinder cover, and then enters in the water jacket of the cylinder body from a gasket circulating hole of the cylinder cover to cool the cylinder body and the EGR cooler. The cooling liquid in the cooling system firstly cools the cylinder cover to reduce the temperature of the cylinder cover by 10 DEG C to 15 DEG C, enhance aeration efficiency, enlarge air inlet quantity, promote complete combustion, reduce the formation of discharge objects andenhance output efficiency; After cooling the cylinder cover, the cooling liquid enters in the cylinder body for cooling the cylinder body; the higher temperature of the cylinder body can reduce friction, improve fuel efficiency, enhance the output efficiency and reduce peak value pressure and temperature in the cylinder.
