摘要： A variable capacity vane compressor has a cylinder including a cam ring having an inner peripheral surface with an oblong cross section and within which a rotor is rotatably received, a plurality of vanes carried by the rotor, and a control plate disposed in the cylinder for rotation in opposite circumferential directions and having a peripheral edge formed with at least one cut-out portion. The control plate is disposed to rotate in response to a difference between pressure from a lower pressure zone and pressure from a higher pressure zone to cause a change in the circumferential position of the cut-out portion, thereby varying the compression commencing timing of the compressor and hence the capacity of same. The cut-out portion of the control plate comprises a first portion circumferentially extending from a downstream end of the cut-out portion with respect to the direction of rotation of the rotor to an intermediate portion of the same, and a second portion circumferentially extending from the intermediate portion to an upstream end of the cut-out portion, and being shallower than the first portion. The cut-out portion has such a circumferential position and length that the second portion is positioned radially inwardly of the inner peripheral surface of the cam ring and has an upstream end and a downstream end thereof positioned, respectively, upstream of a downstream end of an inlet port formed in the cylinder and downstream of same, when the control plate member is circumferentially displaced to an extreme circumferential position in which the minimum capacity of the compressor is obtained, whereby unnecessary compression is prevented.

摘要： A vane compressor has a communication passageway extending between a discharge pressure chamber and vane back pressure chambers. A valve is formed of a ball received within a ball-receiving bore and displaceable for opening and closing the communication passageway depending upon discharge pressure, a coiled spring urging the ball toward a valve opening position, and a stopper for stopping the ball in the valve opening position. The ball-receiving bore has an axial length smaller than an inner diameter thereof such that part of the ball is projected from the ball-receiving bore into the discharge pressure chamber when the ball is in the valve opening position.

摘要： A variable capacity type compressor in which a control element is mounted in one of side blocks formed with inlet ports for rotation about its own axis in opposite circumferential directions between a first extreme position providing the maximum capacity of the compressor, and a second extreme position providing the minimum capacity of the compressor, to vary the compression starting timing. The control element has cut-out portions through which compression medium is drawn into compression spaces, of which one upstream end with respect to the direction of rotor rotation determines the compression starting timing in cooperation with vanes passing same. The cut-out portion is formed of first and second portions circumferentially arranged. At least one recess is formed in an end face of the cam ring facing the control element, which opens in the camming inner peripheral surface thereof and circumferentially extends from a circumferential location at which a suction stroke is started in a compression space within the cylinder or from a point proximate thereto, toward a downstream side with respect to the direction of rotor rotation. The recess is disposed such that when the control element is in the second extreme position, the recess has a downstream end thereof with respect to the direction of rotor rotation positioned downstream of another end of the cut-out portion. The cut-out portion may further be formed with a third portion circumferentially extending continuously from the second portion toward an upstream side with respect to the direction of rotor rotation.

摘要： A variable capacity vane compressor having compression spaces defined between a cylinder and a rotor at diametrically opposite locations. A control element rotatably arranged in the cylinder, which has two cut-out portions circumferentially extending at diametrically opposite locations through which inlet ports and respective corresponding compression spaces are communicatable with each other. The cut-out portions are disposed relative to the respective corresponding compression spaces such that compression commences in each of the compression spaces when a trailing vane passes a forward end edge of a corresponding cut-out portion with respect to the rotation of the rotor. The control element is rotatable between a partial capacity position and a full capacity position for varying the capacity of the compressor. The forward end edge of one cut-out portion associated with one compression space has a circumferentially extending recess formed in a radially inner portion thereof, and a projecting portion formed by a radially outer portion thereof, whereby compression commences in the one compression space at retarded timing as compared with the other compression space when the control elements is in the full capacity position.
