摘要： Pressurized injector actuation fluid is supplied to high pressure common rail (28) by a fixed displacement fluid pump (26). Variable delivery from the pump (26) is achieved by selectively spilling pumped fluid through a digital-acting by-pass or spill valve (90). The by-pass valve (90) is actuated by a momentary electric signal, which causes internal fluid pressure in the valve (90) to latch it in a closed condition, thus permitting high precision variations in the pump delivery with rapid response times. Unit pump (26), radial pump (400), and axial pump (500) configurations are disclosed. Variable delivery is achieved in another embodiment by an improved sleeve metering approach. The sleeve (692) surrounds the reciprocating piston (672) and is manipulated to control venting of pumped fluid through vent ports (686) in the piston (672). The sleeve (692) is moved by preferably being the armature of a solenoid assembly (698). The varying of current to the solenoid coil (696) alters the axial position of the sleeve (692) relative to the piston (672) to vary its effective pumping stroke.

摘要： A variable displacement compressor includes a swash plate (31) and a displacement control valve (46; 88). The swash plate is moved between a maximum inclination position and a minimum inclination position in accordance with the pressure in a crank chamber (15). The control valve changes the crank chamber pressure to change the swash plate inclination. The control valve includes a valve body (52; 96) and an electromagnetic actuator (60, 61, 64; 97) for moving the valve body. Movement of the valve body is controlled according to current supplied to the actuator. The control valve also includes a fluid damper (90, 91; 59, 61) for applying fluid resistance to the valve body. The fluid resistance prevents the valve body from moving too quickly. The fluid damper therefore prevents the crank chamber pressure from being suddenly changed. Also, the fluid damper prevents the swash plate inclination from being suddenly changed. Instead of using the fluid damper, the sudden movement of the valve body may be prevented by controlling current supplied to the electromagnetic actuator.

摘要： The air conditioning system 100 may include a compressor 101, a heating circuit 152, and a refrigerant releaser 181. The compressor 101 may have a suction port 115 for drawing refrigerant and a discharge port for 120 discharging compressed refrigerant. The heating circuit 152 has a passage 152a that extends from the discharge port 120 to the suction port 115 though a heat exchanger 159.
The refrigerant releaser 181 may release the refrigerant from the discharge port 120 to the suction port 115 when the discharge pressure Pd of the refrigerant results a predetermined high-pressure state during the operation of the heating circuit 152.
The air conditioning system 100 can solve a problem of insufficient heating performance due to releasing the refrigerant in the heating circuit into the cooling circuit to alleviate the abnormally high-pressure state during operation of the heating circuit.

摘要： Disclosed is a fuel injection system for an internal combustion engine, comprising a presupply pump (2) and a high-pressure pump (16) used to pump pressurized fuel into a common rail (18). The supply pressure of the high-pressure pump (16) is brought to a high level of pressure when the internal combustion engine is started, whereby the pressure in the common rail (18) required for optimum atomization can be built up very quickly.
