摘要： A refrigeration suction mechanism used in a piston type compressor. The compressor comprises a rotary shaft, a plurality of pistons, a compression chamber and a rotary valve. The pistons are arranged in a circumference of the rotary shaft to reciprocate in conjunction with a rotating motion of the rotary shaft through a cam member. An end surface of one of said pistons reciprocates in the compression chamber. The rotary valve includes an introducing passage which allows refrigerant to flow into the compression mechanism through an end opened on an outer surface of the rotary valve. The refrigeration suction mechanism comprises a suction passage and a reactive force transmitting mechanism. The suction passage communicates with the cylinder bore and intermittently communicates with the end of the introducing passage in conjunction with a rotating motion of the rotary valve. The reactive force transmitting mechanism transmits a reactive force applied on one of the pistons that is in a discharging stroke so as to press the rotary valve against a mouth of the suction passage which communicates with a cylinder bore that contains the piston in the discharging stroke.

摘要： A vehicle air conditioning apparatus includes a refrigerant circulation circuit. The vehicle air conditioning apparatus has a variable displacement type compressor, a first pressure monitoring point, a second pressure monitoring point and an oil separator in the refrigerant circulation circuit. Also, the vehicle air conditioning apparatus has a control valve in the compressor. The compressor compresses refrigerant gas. Displacement of the compressor is variable. The refrigerant gas includes oil. The second pressure monitoring point is located more downstream than the first pressure monitoring point. The control valve controls the displacement based on differential pressure between the first and second pressure monitoring points. The oil separator is located between the first and second pressure monitoring points in order to separate the oil from the compressed refrigerant gas, thereby the oil separator serves as means for manifesting the differential pressure.

摘要： A control apparatus that promptly increases the displacement of a compressor after the compressor is started while liquefied refrigerant is lingering in an external circuit. The control apparatus includes a restricting passage. The restricting passage is located in a first pressure introduction passage, through which the pressure of the first pressure monitoring point flows to the control valve. The restricting passage decreases the pressure of refrigerant that flows through the passage. When the compressor is started while liquefied refrigerant is lingering in the external circuit and the pressure of the first pressure monitoring point is abruptly increased, the restricting passage reduces the increase of the pressure that is detected by the control valve. Therefore, the displacement of the compressor is promptly increased.

摘要： A variable displacement compressor includes a bleed passage for releasing gas from a crank chamber to a suction chamber and a supply passage for supplying gas from a discharge chamber to the crank chamber. A control valve includes an outlet valve mechanism located in the bleed passage and an inlet valve mechanism located in the supply passage. When the inlet valve mechanism is in the open state, the outlet valve mechanism is in the closed state. An outlet valve body of the outlet valve mechanism has a communication passage. When the outlet valve mechanism is in the closed state, the communication passage is opened to communicate the crank chamber with the suction chamber. Therefore, when the compressor is operating at the minimum displacement, a gas circuit is positively formed within the compressor, and atomized lubricant in refrigerant gas positively lubricates the moving parts of the compressor.

摘要： Compressor are taught that may include a suction port to draw refrigerant and a discharge port to discharge compressed refrigerant. A driving shaft is disposed within a compressor driving chamber. A swash plate is inclinably and slidably coupled to the driving shaft. The swash plate rotates together with the driving shaft at an inclination angle with respect to a plane perpendicular to the rotational axis of the driving shaft. A cylinder bore is disposed adjacent to the compressor driving chamber. A piston is disposed within the cylinder bore and an end portion of the piston is connected to a peripheral edge of the swash plate by a shoe. Preferably, the piston reciprocates within the cylinder bore to compress the refrigerant in response to rotation of the inclined swash plate. A rotor is connected to the driving shaft. A hinge mechanism connects the swash plate with the rotor and transmits torque from the driving shaft to the swash plate regardless of the inclination angle of the swash plate. The hinge mechanism includes a projection disposed on one of the rotor or the swash plate and at least one arm disposed on the other of the rotor or the swash plate. The projection has a recessed structure and at least one arm is coupled to the projection to transmit torque from the driving shaft.

摘要： A valve housing of the control valve has a communication passage communicating a suction port of the compressor with a crank chamber of the compressor. A main valve is provided in the valve housing for opening and closing the communication passage. A spring member resiliently biases the main valve toward its closed position. A pressure actuated unit moves the main valve toward the open position by receiving a suction pressure of the compressor. A flow adjustment valve is disposed in the valve housing for adjusting an open degree of a leak passage and receives the discharge pressure exerting a force on the flow adjustment valve toward its closed position. The flow adjustment valve increases a leak flow rate of a fluid flowing from a discharge port of the compressor to a crank chamber through a leak passage when the compressor provides a lower discharge pressure. A correction spring is disposed between the main valve and the flow adjustment valve. The correction spring resiliently biases a valve element of the main valve toward the open position and increases in spring force with transfer of a valve element of the flow adjustment valve toward its closed position.
