摘要： This invention provides a chemical supply system for supplying chemical solution from a chemical tank. The chemical supply system includes a chemical supply pump, a pressure adjuster configured to suction the chemical solution into the pump chamber by setting the pressure of working gas to a suction pressure, a switching controller configured to switch the suction-side opening-closing valve to the open state for starting to fill the pump chamber with the chemical solution, a pressure detector configured to detect at least one of a gas pressure in a space connected to the working chamber and a gas pressure in the working chamber when the suction-side opening-closing valve is switched to the open state and starts an inflow of the chemical solution to the pump chamber, and a suction controller configured to control the suction pressure applied to the working chamber by the pressure adjuster, based on a detection result of the pressure detector.

摘要： An assembly for testing an evaporative emission control system of an automotive vehicle which controls emission of volatile fuel vapors. The assembly is used to determine if a leak is present in a portion of the system which includes a vapor collection canister. The leak detection assembly incorporates a vacuum actuated canister vent control valve which seals the evaporative system so the leak detection test can be performed. A vacuum actuated pump which performs a leak detection test. An engine control unit initializes the pump by drawing air into a pump cavity and also closes the vent control valve. After the initialization period, the pump is activated to pressurize the evaporative emission control system. Once a control pressure is achieved, the cycle rate starts to drop off. If no leak exists in the system, the pump will eventually stop pumping. If there is a leak, the pump will continue to pump at a rate that will be representative of the flow characteristics of the size of the leak. After the test has been concluded, the vent control valve will unseal the system after the vacuum has been bled out through the orifice/check valve that has been holding the seal during the test.

摘要： A pneumatic metering pump apparatus, having a pump member, working in combination with power head means wherein a pneumatically driven piston would cooperate with the pump means. There would be further provided a fluid inlet providing fluid flow to the power head and a valving element in communication with the first fluid inlet and the piston. Further, a timer would be in fluid communication with the valve and piston, would also include a valving element housed in the valving member for providing fluid communication between the valving member and the piston when the valving member is in the first position and blocking fluid communication between the valving member and the piston and establish fluid communication between the piston and an exhaust when the valving member is in a second position.

摘要： An air compressor for inflating pneumatic tires of a motor vehicle is particularly adapted to be powered by the negative pressure created at the intake manifold of the vehicle engine. The piston of a reciprocating air pump has a direct mechanical coupling with the plunger of a pneumatic cylinder assembly for driving the air pump. The cylinder assembly in turn is operated by the negative pressure of the intake manifold through a unique valve control system which automatically directs the negative pressure flow in a manner to reciprocate the plunger and hence, drive the air pump piston. In preferred forms, the plunger presents a greater operating area than the air pump piston whereby a pressure multiplying effect is provided to obtain the relatively high inflation pressures required for many pneumatic tires.
