摘要： A swash plate is mounted on a drive shaft disposed in a housing having a gas suction chamber in such a way that the swash plate is rotatable integrally with the drive shaft. A plurality of cylinder bores are formed around the drive shaft, extending along the drive shaft. Disposed in each cylinder bore is a piston, which reciprocates between top and bottom dead centers by undulating movement of the swash plate caused by rotation of the drive shaft. A compression chamber where gas is compressed by the reciprocal movement of the piston is defined in each cylinder bore. Provided between the drive shaft and the swash plate is a mechanism for altering an angle of the swash plate with respect to the axis of the drive shaft to change a reciprocal stroke of the piston to thereby control compression displacement. A rotary valve is provided at the drive shaft to be rotatable integrally with the drive shaft. The rotary valve has a passage for permitting uncompressed gas to move to each compression chamber from the suction chamber in synchronism with the reciprocal movement of the piston during rotation of the rotary valve before the piston reaches the bottom dead center. The compressor further comprises a mechanism for forcibly changing the timing at which the piston substantially reaches the top dead center in accordance with an inclined angle of the swash plate.

摘要： A variable displacement type swash plate compressor that prevents a drive shaft from moving axially when the difference between a crank chamber pressure and a cylinder bore pressure becomes excessive. A hinge mechanism has a support arm extending from a lug plate and a guide pin extends from a swash plate. The head portion of the guide pin fits in a guide hole formed in the support arm. A cutaway surface is formed in a part of the support arm that defines the guide hole. The cutaway surface forms a clearance in the hinge. The clearance permits the swash plate to move without pulling the drive shaft.

摘要： A control valve is used in connection with a variable displacement compressor that varies the discharge capacity by controlling an inclination of a cam plate located in a crank chamber. The inclination of the cam plate is variable based on crank chamber pressure caused by refrigerant in the crank chamber. Monitor pressure is monitored at a predetermined point in a refrigerant circuit for causing a change in the crank chamber pressure and ultimately varying the discharge capacity. The control valve has a housing, an internal control valve mechanism and an external control valve mechanism. The internal control valve mechanism is located inside the valve housing and has a first valve body and a first reacting member. The first reacting member is connected to the first valve body for reacting to the monitor pressure to cause a change in the crank chamber pressure. The external control valve mechanism is located inside the valve housing and has a second valve body and a second reacting member. The second reacting member is for reacting to an external signal to cause the second valve body to change in the crank chamber pressure. The internal control valve mechanism and the external control valve mechanism operate independently with each other.

摘要： An axial multi-piston compressor includes a drive shaft, a cylinder block having cylinder bores formed therein and surrounding the drive shaft, and a plurality of pistons slidably received in the respective cylinder bores, wherein the pistons are successively reciprocated in the cylinder bores by a rotation of the drive shaft so that a suction stroke and a discharge stroke are alternately executed in each of the cylinder bores. During the suction stroke, a fluid is introduced into the cylinder bore, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore such that a residual part of the compressed fluid is inevitably left in the cylinder bore when the compression stroke is finished. The compressor further includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore governed by the compression stroke.

摘要： In a swash-plate compressor, pistons are slidably received in cylinder bores. A drive shaft is extended through a crank chamber, and is rotated through an electromagnetic clutch means associated therewith. A conversion mechanism is provided on the shaft for converting a rotational movement of the shaft into a reciprocation of each piston in the corresponding cylinder bore such that a suction stroke and a discharge stroke are alternately executed therein. A fluid is introduced from a suction chamber into the bore during the suction stroke, and during the compression stroke, the fluid is compressed in and discharged from the bore into a discharge chamber. The conversion mechanism is constituted such that a stroke length is shortened in response to an increase of a pressure in the crank chamber, and vice versa. A first passage communicates the crank with the suction chamber, and a second passage communicates the crank chamber with the discharge chamber. A control valve is provided in one of the first or second passage, and is magnetically actuated by the clutch for controlling the pressure in the crank chamber such that the piston stroke can be minimized whenever the clutch is electrically deenergized.

摘要： A variable displacement compressor is disclosed having an improved pivotal mounting between its drive plate and the rotary journal that carries the swash plate. The pivotal mounting structure includes a bearing and a pin. The bearing is pivotally mounted on the drive plate. The pin couples the drive plate to the rotary journal. The pin is slidably mounted in a slot in the bearing so that when the bearing and rotary journal pivot, the pin may slide with in the slot. With this arrangement, the point at which a load from the journal is transferred to the drive plate remains substantially fixed regardless of the inclination angle of the journal.
