Abstract: A lubricating mixture of a lubricant and air is supplied to a cutting location by a lubricating tool with a spring biased piston dividing a cylinder into an air chamber and a lubricant chamber. The air chamber is connectable to a pressurized air source. The lubricant supply chamber is selectively connectable through a control valve to a lubricant source or to an exchangeable lubricant and air mixing attachment also connected to the pressurized air source. The attachment includes three flow restrictors. Two restrictors feed air and lubricant to a mixing area. One restrictor feeds the mixture to an output. Different sets of restrictors with different flow restricting characteristics provide an exact mixture dosage for satisfying any cutter lubricating requirement. It is merely necessary to replace one attachment by another attachment having different flow restricting characteristics.

Abstract: A lubrication medium supply system and method for delivering lubricant to, for example, the spin bearings of a control moment gyro (CMG), includes a reservoir, a motor, and a valve. A lubrication medium is placed within the reservoir, and the motor, which is coupled to the reservoir, compresses, and thereby pressurizes, the lubrication medium. The valve opens in response to the pressurization of the lubrication medium, to thereby dispense a predetermined amount of lubrication medium from the reservoir, while simultaneously depressurizing the lubrication medium in the reservoir.

A first adapter assembly enables a conduit hose of a flushing apparatus to be connected with the drain plug port of the engine crankcase via a specialized adapter piece and a universal adapter piece. The uniform adapter piece forms a threaded connection with the specialized adapter piece for attachment to the conduit hose of the flushing apparatus. A second adapter assembly for coupling a second hose of the flushing apparatus also includes one of a plurality of specialized adapter elements selected to fit the oil filter port of a particular automobile engine and a universal adapter element connected by a bayonet coupling between the specialized adapter and a second conduit hose of the flushing apparatus.

Abstract: In order to provide method of atomizing lubricant at a constant rate in a lubricant atomizer irrespective of the kinds of lubricant and the working conditions, the lubricant atomizer includes a compressed air valve having two branches on its downstream side, which one of two branches is connected to a Venturi mechanism, and the other branch is connected to a constant lubricant supplying pump. Compressed air is fed from the compressed air valve to the Venturi mechanism and to the constant lubricant-supplying pump, thus drawing the air from a sight dome while the compressed air is flowing in the Venturi mechanism. Lubricant is pumped to the sight dome via a constant lubricant supplying conduit, allowing the lubricant to fall in the center of the Venturi mechanism in the form of droplets.

Abstract: In one exemplary embodiment, the lubrication system includes a valve between the fluid conduit and the fluid pump, a sensor configured to generate a signal indicative of a viscosity of the fluid and an actuator coupled to the valve, wherein the actuator opens and closes the valve in response to the signal from the sensor. A method for lubricating and cooling an axle within a housing includes the steps of pumping fluid from a reservoir through a first passage having a first cross sectional area, through a second adjacent passage having a second smaller cross sectional area and through a third passage having a third cross sectional area greater than the second cross sectional area to the interior of the housing. The method also includes the step of providing a source of air to the fluid after the fluid exits the second passage. Air is drawn into the fluid to aerate the fluid. The aerated fluid expels fluid from the interior of the housing to the fluid reservoir.

Abstract: A liquid coater which includes a mist feed tube (5) for feeding oil mist into an airtight container (2), an air hose (10) for feeding air into the airtight container (2) and a mist conveyor pipe (11) for conveying the oil mist pressurized by air inside the airtight container (2) to the outside of the container. Therefore, droplets and large mist particles can be trapped inside the container from the mist feed tube (5), and the mist can be conveyed at a high speed. The liquid coater has excellent applicability. The mist feed tube (5) has a double tube structure comprising an air tube (7) in which air flows, and an oil tube (6) which extends in the air tube (7) and in which the oil flows. The distal end of the oil tube (6) is positioned more inward than the distal end of the air tube (7), so that the oil mist can be fed by a simple construction.

Abstract: A pressure fluid-driven apparatus includes a zero point position-determining mechanism, including an oil supply-adjusting knob formed with an arrow-shaped recess for indicating a zero point position, an insert member internally fitted into a hole of the oil supply-adjusting knob, a stopper for setting an assembled state of the oil supply-adjusting knob and the insert member to be at a zero point position, and a first spline section and a second spline section fitted to one another to determine the position so that the zero point position of the recess corresponds to that of a holder.

Abstract: Apparatus and methods for flushing and cleaning the oil strainer and crankcase of an internal combustion engine of a type having a removable full-flow oil filter. The oil filter is temporarily replaced with a cartridge which has at least one passage therethrough which will communicate with the discharge side of the engine oil pump but does not communicate with the normal outflow port of the filter apparatus. A second passage therethrough may communicate with the outflow port of the filter system but does not communicate with the discharge of the oil pump. In a preferred method, the inlet of the first passage may be connected to a source of pressurized fluid to force the fluid, in a direction opposite to normal flow, through the passage, the oil pump and the oil strainer to agitate and flush contaminants in the oil strainer and crankcase. The pressurized fluid and contaminants are drained from the crankcase after which the cartridge is removed, a new oil filter installed and clean oil added to the engine.

Abstract: Oil changing apparatus including an oil storage tank and a gasoline powered air compressor, both mounted on the bed of a trailer. An oil hose communicates with the storage tank, and connects into a motor being serviced. The drain plugs of motorized equipment serviced by the oil changing apparatus are provided with quick coupling connectors. The oil hose has a cooperating connector at its distal end, which connects to the modified drain plug. The drain plug connector includes a normally closed valve, to retain oil in the sump when the oil hose is not attached thereto. A first air hose enables the air compressor to draw air from the storage tank in the oil drain mode. Oil is removed from the serviced motor by suction. In the purge mode, accumulated old oil is rapidly purged from the tank. A second air hose conducts pressurized air from the compressor to the storage tank, which forces oil from the storage tank when emptying the same. An accessory enables purging an oil filter cartridge with the novel apparatus.

Abstract: A system for providing total fluid exchange for an automatic transmission which interconnects with the transmission's opened cooling circuit to deliver new, fresh fluid to the transmission while simultaneously extracting the spent, used fluid. The system provides a means of quick and random interconnection to an opened cooling circuit and means of identifying and aligning direction of flow in such cooling circuit. The system can accurately calibrate and regulate the rate that fresh fluid will flow into the transmission to be the same as that at which the used fluid is extracted, both of which are regulated to flow at the same rate that fluid normally circulates at in the cooling circuit when it is closed under similar operating conditions.
