    摘要: A compressor includes a discharge chamber and a retaining passage, which is located downstream of the discharge chamber. A control valve controls the displacement of the compressor in relation to the pressure difference between a first pressure monitoring point in the discharge chamber and a second pressure monitoring point in the retaining passage. A pressure introducing passage connects the retaining passage to the control valve. The pressure introducing passage has an opening to the retaining passage. An inlet member is located in the retaining passage to cover the opening. The inlet member has a pressure introducing port that functions as the second pressure monitoring point. The pressure of the refrigerant in the retaining passage is supplied from the pressure introducing port to the control valve through the pressure introducing passage. The inlet member easily alters the position of the pressure introducing port in the retaining passage.

    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: An external control variable displacement compressor varies its displacement based on the pressure in a control chamber. The compressor has a valve chamber defined in a housing. The valve chamber has an opening to accommodate an electrically operative control valve. The control valve controls pressure in the control chamber due to an external electrical signal. An electrical power supply line is connected to the control valve, the power supply line being in contact with an opening of the valve chamber. The valve chamber opening is surrounded by a circumferential wall. An agonic surface formed on the circumferential wall is constituted of a rounded surface formed by rounding a corner of the opening and/or a chamfered surface formed by chamfering a top of the opening, and is formed on a part of or the entire circumferential wall. The power supply line is to be in contact with the agonic surface.

    摘要: A control valve is located in a variable displacement compressor incorporated in a refrigerant circuit. The control valve controls the displacement of the compressor in accordance with a pressure difference between a first pressure monitoring point and a second pressure monitoring point, which are located in the refrigerant circuit, such that the pressure difference seeks a predetermined target value. An adjusting valve, which is a variable throttle valve, is located in a section of the refrigerant circuit between the first and second pressure monitoring points. The adjusting valve adjusts the restriction amount of the refrigerant in relation to the refrigerant flow in the refrigerant circuit. The compressor displacement is thus optimally controlled.

    摘要: An air conditioner having a refrigerant circuit that maintains a high cooling efficiency and a sufficient amount of oil returned to a compressor even if the flow rate of refrigerant is decreased due to a low cooling load is provided. The refrigerant circuit includes a condenser, an expansion valve, an evaporator and a variable displacement compressor. The expansion valve is normal-charge type. A control valve adjusts the pressure in a crank chamber based on the value of a current from a controller and on a pressure difference between two pressure monitoring points, which are located in the refrigerant circuit. Accordingly, the compressor displacement and the flow rate of refrigerant in the circuit are controlled.

    摘要: A vehicle air conditioning apparatus includes a refrigerant circuit. The air conditioning apparatus is driven by an engine. The air conditioning apparatus includes a variable displacement compressor. An external information detector detects external information used for the air conditioning. An E/G-ECU controls the output of the power source. An A/C-ECU is connected to the E/G-ECU via a communication line. The A/C-ECU computes a target value of the displacement of the compressor based on the external information. The A/C-ECU sends the computed target value to the E/G-ECU. The E/G-ECU controls the displacement of the compressor based on the computed target value. This is capable of rapidly changing the discharge displacement in accordance with the driving condition of the engine.

    摘要: A valve body adjusts opening of a supply passage in response to the position in a valve chamber. A pressure-sensitive member is moved in accordance with the pressure difference between two pressure monitoring points, which are located in an external refrigerant circuit. The movement of the pressure-sensitive member affects the position of the valve body such that the compressor displacement is changed to reduce fluctuations in the pressure difference. A solenoid changes force applied to the valve body so that a set pressure difference, which is a reference value for changing the position of the valve body by the pressure-sensitive member, is changed.

    摘要: An air-conditioning system with a refrigerant circulation circuit, which has improved control precision for maintaining a compartment temperature and improved response characteristics. The refrigerant circulation circuit includes a variable displacement type compressor, the discharge capacity of which is controlled by a control valve. The control valve detects a differential pressure between two pressure monitoring points in the refrigerant circulation circuit as an index for estimating the refrigerant discharge capacity of the variable displacement type compressor and performs feedback control of the discharge capacity of the compressor such that the differential pressure converges to a set differential pressure. A controller determines or recomputes the set differential pressure based on information from a mode switching unit or an air-flow-rate switch and instructs the control valve to change the set differential pressure accordingly. The switch information from the mode switching unit or the air-flow-rate switch signals the controller of a sudden change in the cooling load before the occurrence of the change or at the same time as the change occurs.
