摘要： In a traditional hybrid air engine it is complicated to adjust valve timing to compensate for different engine operating modes. Provided is an air compression method and apparatus. The air compression method can be carried out in a single stage with a plurality of air tanks (61, 63) coupled to a compressor (51). The compressor (51) may be a cylinder Air is added to the compressor (51) at atmospheric pressure. Pressurized air is then added to the compressor (51) from a low pressure air tank (61). The compressor (51) compresses the air and transfers a portion of it to a high pressure air tank (63). The remaining portion of the compressed air is transferred to the low pressure air tank (61) for use in the next compression cycle A cam shaft (27) having a two stroke cam (93) and a four stroke cam (95) for each intake valve (59) and exhaust valve (55, 57) is provided to control valve timing during different operating modes.

摘要： A compressor may include a crankcase, a crankshaft, a piston, a discharge valve and a suction plenum. The crankcase defines a discharge plenum receiving working fluid at a first pressure. The crankshaft is disposed within the discharge plenum. The piston is drivingly connected to the crankshaft and reciprocatingly received in a cylinder. The piston and cylinder cooperate to define a compression chamber therebetween. The discharge valve may control fluid flow through a discharge passage between the compression chamber and the discharge plenum. The suction plenum may receive working fluid at a second pressure that is less than the first pressure. The suction plenum may provide working fluid at the second pressure to the compression chamber.

摘要： A compressor system for a compressed-air supply arrangement includes an adjustable throttle device arranged in the suction line of the compressor. The throttle device is adjustable between a fully open load position and an idle position with a predefined narrowed throttle cross section. The idle power of the compressor is reduced as a result of the reduction of the pressure level downstream of the throttle device without additional lines, filters or the like.

摘要： There is provided a flow rate control valve of a constant flow-rate control type, which is simple in construction. The flow rate control valve is configured, by regarding a evaporator as a restriction passage, to include a constant differential pressure control valve for controlling the differential pressure before and after pressure loss caused by passage of refrigerant through the evaporator to be substantially constant. In the constant differential pressure control valve, a valve element receives pressure from the outlet of the flow rate control valve in a valve-closing direction, and a piston receives pressure from the outlet of the evaporator in a valve-opening direction. By controlling the differential pressure between pressure at the inlet of the evaporator and the pressure at the outlet of the evaporator such that it is substantially constant, the constant differential pressure control valve causes the refrigerant to flow into the evaporator at a constant flow rate dependent on electric current that energizes a solenoid. This makes it unnecessary to form a restriction passage in the flow rate control valve, and hence the construction of the flow rate control valve can be simplified, which makes it possible to provide a flow rate control valve manufactured at low cost.

A pilot-operated device is included that is configured to selectively drive the tool with pressure from at least one of the output of the low-pressure pump and the output of the high-pressure pump. The pilot-operated device receives pilot pressure from the output of the low-pressure pump to control selectively driving the tool with the output of the two stage pump.
