The invention relates to the field of machining, in particular to a nano particle jet flow micro-scale lubricating and grinding three-phase flow supply system. The system is characterized in that: nano fluid is conveyed to a nozzle by a liquid path, high temperature gas enters the nozzle through a gas path at the same time, the high pressure gas and the nano fluid are fully mixed and atomized in the mixing room of the nozzle, the mixed high pressure gas and nano fluid are accelerated in an acceleration room and enter a vortex room, compressed gas enters from the vent hole of the vortex room, and a three-phase flow is further mixed and accelerated by rotating, and is jetted in the form of atomized liquid drops to a grinding area through the outlet of the nozzle. The system has the advantages that: the helical vent hole of the mixing room of the nozzle is tangent to the wall surface of the mixing room, and the nano fluid and the gas are uniformly mixed; pressure adjusting valves, throttles and flow meters are arranged in the gas path and the liquid path, and the pressure and the flow of the nano fluid and the high pressure gas can be adjusted as required so as to achieve an optimal micro-scale lubricating effect; and the problems of insufficient cooling capability in micro-scale lubricating, the large using quantity of a lubricant in pouring type grinding, high waste liquid processing cost and heavy environment pollution are solved.

This invention performs several functions. First; facilitating the draining of oil or fluid from a sump. Second; as a proactive and preventive method of preventing the threads of the sump (which receive the drain plug) from becoming striped or damaged. Third; adding in the determination of the physical condition (ware) of the engine, transmission, or the like, in which the sump is attached to.

A lubrication dispensing apparatus for lubricating a device with moving parts includes a lubricant reservoir, a lubricant dispenser for dispensing lubricant from the lubricant reservoir, an ultrasonic detection module which detects the amplitude of ultrasonic energy emitted by said device when its parts are moving and produces an signal related thereto, and a control module which analyzes the amplitude of the signal from the ultrasonic detection module and, in response to a lubricate signal, causes the lubricant dispenser to automatically dispense lubricant onto the moving parts of the device until the signal from the ultrasonic detector indicates that the ultrasonic energy produced by the device has decreased to a particular level. The control module includes a programmed processor and a storage memory. The memory stores as a base value the value of the detected amplitude of ultrasonic energy when the device is operating properly. After receiving a signal to lubricate the device, the processor causes the dispenser to start the flow of lubricant to the device, compares the signal from the ultrasonic detection module when the parts are moving to the base value, and causes the dispenser to cease the flow of lubricant when the signal substantially decreases.

A battery operated grease gun has a motor that drives a planetary gear assembly that is coupled to a pump assembly that drives a plunger reciprocally in an grease passage to discharge grease through a discharge spout. The pressure in the grease exerts a reaction force on the plunger that will change torque of the motor. The change of the torque of the motor will simultaneously effect voltage applied to the motor. When the voltage in the motor changes, an electronic pressure regulator measures the voltage in the motor to determine the pressure in the grease in the grease passage and stops the motor as the pressure in the grease reaches preset given valves in the pressure regulating device.

A fluid reservoir assembly having a pan defining a drain opening and a plug disposed therein is disclosed. The pan includes a pair of ramps disposed on an inner surface thereof adjacent the drain opening. The plug includes a pair of wings in engagement with the ramps. The ramps increase in height relative to the inner surface of the pan along a first direction of rotation about the central axis. The plug is drawn into sealing engagement with an outer surface of the pan by rotating the plug in the first direction of rotation about the central axis thereby moving the wings up the ramps. The pan includes at least one stop to prevent over-rotation of the plug. The ramps define a recess to secure the wings in a closed position.

An automatic lubrication system for a vehicle, comprising a pump assembly having a plurality of outlet ports, a motor operable to drive the pump assembly, and a cartridge that is attachable to the pump assembly to provide a source of lubricant to the pump. The cartridge is removable from the pump assembly and has an interior space that is collapsible as lubricant is dispensed therefrom. A controller is provided to periodically initiate the motor to cause the pump to dispense lubricant to the outlet ports.

A hydraulically driven intensifier for increasing pressure of gas comprising a piston-driven compression chamber for gas, operatively connected to an adjacent hydraulic chamber, with lubricant coupling in the compression chamber of the intensifier to circulate the lubricating fluid for cooling and lubricating the piston. A multistage compression system for gas, comprising the aforementioned intensifier, preferably several thereof operatively connected in series.

An improved grease coupler 3 allows for positive, coupling and uncoupling from a grease nipple 4 via a manually operated trigger mechanism 30. The coupler includes a replaceable seal 13 and has an elongate body 10 with a grease passage 11 through the length of the body. A floating barrel plunger 42 acts as a check valve to prevent grease leaking from the discharge end of the elongate body 10 upon disconnection.

A battery powered grease gun is disclosed. One embodiment has an overpressure relief valve for returning grease to the grease barrel mounted to the grease gun head when a plugged zerk prevents grease from exiting the output port. The grease gun head may be additionally provided with a sampling duct which is joined to an output port. The sampling duct couples the output port to another port in which a pressure gauge or a pressure transducer may be installed. In one embodiment, a strain gauge based pressure transducer may be attached to the grease gun to monitor the flow and pressure of grease in the grease gun. The pressure and/or flow of grease may be displayed on the pressure gauge or on a display coupled to the transducer.

A transmission fluid sump for an automotive transmission comprising a reservoir portion, a threaded extension on the reservoir portion and a fill pipe threadably connected to the extension. A closure member seals a central opening in the extension independently of the fill pipe, thereby avoiding overlapping torque windows for the fill pipe and the closure member while providing a single leak flow path for the transmission fluid.
