摘要： A variable capacity wobble plate compressor includes a first spring, fitted on a drive shaft between a hinge ball axially slidably fitted on the drive shaft and a thrust flange rigidly fitted on the drive shaft, for urging the hinge ball toward a cylinder block, and a second spring fitted on the drive shaft between the hinge ball and the cylinder block for urging the hinge ball toward the thrust flange. As the hinge ball is moved toward the thrust flange, a linkage connecting a drive hub slidably mounted on the hinge ball a causes an inclination of the drive hub to be increased to increase capacity of the compressor, and as the hinge ball is moved toward the cylinder block, the linkage causes the inclination of the drive hub to be decreased to decrease the capacity of the compressor. A first stopper blocks the hinge ball from moving toward the thrust flange in excess of a predetermined amount, to thereby restrict an increase in the inclination of the drive hub and set the maximum capacity of the compressor. A second stopper blocks the hinge ball from moving toward the cylinder block in excess of a predetermined amount to thereby set the minimum capacity of the compressor.

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 vane compressor is provided with a control valve device having a deformable member disposed within a zone under low pressure for expansion and contraction in response to pressure therein. A pressure-responsive control device is associated with the control valve device for controlling the capacity of the compressor. The deformable member contracts and causes the control device to bring the compressor into full-capacity operation when the pressure within the zone under low pressure is higher than a predetermined value, whereas the deformable member expands and causes the control device to bring the compressor into partial-capacity operation when the pressure within the zone under low pressure is lower than the predetermined value. A device is provided which is operable in response to excessive expansion of the deformable member for causing the control device to bring the compressor into full-capacity operation.

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 variable capacity vane compressor has an annular control element angularly displaceably received within an annular recess formed in one of side blocks defining a cylinder. The control element is angularly displaced in response to a difference in pressure between first and second pressure chambers formed in the one side block and communicating with a zone under lower pressure and a zone under higher pressure, respectively, and to the biasing force of a biasing member, thereby varying the opening angle of at least one second inlet port formed in the one side block and hence controlling the capacity of the compressor. A positioning device is provided at a radially inner portion of the control element to radially position the control element in place within the annular recess of the one side block with reference to the radially inner portion of the control element, thus relieving the hysteresis between angular displacement of the control element in one circumferential directions and that in the opposite direction. At least one oil groove is formed in the inner peripheral surface of the control element to guide lubricating oil for lubricating the same element and its associated sliding parts to a sufficient degree to further reduce the hysteresis.
