摘要： PROBLEM TO BE SOLVED: To provide an intake throttle valve for a compressor, having reduced vibration and noises resulting from intake pulsation while maintaining performance over all flow amount range. SOLUTION: The intake throttle valve 37 for adjusting the opening of an intake passage 36 comprises a first valve element 43 arranged movable when receiving intake pressure Ps, and a second valve element 47 arranged movable when receiving crank chamber pressure Pc. A coil spring 49 is provided in a valve chamber 48 between the first valve element 43 and the second valve element 47, and an escape passage 51 is provided for communicating the valve chamber 48 with an intake chamber 29. The escape passage 51 is variably opened with the movement of the second valve element 47 so that it is in a fully opened condition during maximum displacement operation and in a reduced condition during variable displacement operation.

摘要： PROBLEM TO BE SOLVED: To prevent vibration of a swash plate generated during the minimum displacement operation in a variable displacement one side swash plate compressor. SOLUTION: Opposed surfaces 40, 42 are formed on inclined surfaces having angle α to a vertical line Y in lug arms 38, 39 of a lug plate 13. Outside surfaces 47, 48 are inclined to expand with respect to a center axis line X of a drive shaft 8 toward a lug plate 13 side in swash plate arms 45, 46 provided on swash plates. An interval between tip parts of the surfaces 47, 48 is a dimension with which the swash plate arms 45, 46 are inserted between the opposed surfaces 40, 42. An interval at lower end sides of the opposed surfaces 40, 42 is set to dimension with which tip part lower ends of the surfaces 47, 48 substantially partially touch during the minimum displacement operation of the compressor.

摘要： PROBLEM TO BE SOLVED: To provide a variable displacement swash plate type compressor which can control not to be brought into high capacity operation during high speed rotation and which requires no substantial change in a system. SOLUTION: A compressor 10 includes a rotary shaft 17 rotatably supported in a cylinder block 12, a lug plate 21 fixed to the rotary shaft 17, a swash plate 22 supported so as to allow the inclination angle to be changed, and a coil spring 24 for biasing the inclination angle of the swash plate 22 in a decreasing direction, wherein a movable member 36 receiving centrifugal force based on the rotation of the lug plate 21 and tiltable in an axial direction of the rotary shaft 17 taking a spindle 38 as a fulcrum is provided to a surface on the swash plate 22 side of the lug plate 21. The movable member 36 is provided with a weight part 39 disposed separately on the swash plate 22 side and an abutting part 40 for controlling the inclination angle of the swash plate 22 by approaching the swash plate 22 side, keeps a return spring 41 for biasing the abutting part 40 in an opposite direction to the swash plate 22, and is abutted and arranged on a plate member 35 between the lug plate 21 and coil spring 24.

摘要： PROBLEM TO BE SOLVED: To provide a compressor capable of exhibiting superior sliding characteristics and high refrigerating capacity as required. SOLUTION: This compressor comprises a relief passage 62 allowing a crankcase 24 to communicate with a suction chamber 20. The relief passage 62 comprises first passages 12b, 12c, 62, 66, 68, 18a communicating with the inside area of the crankcase 24 where a large quantity of lubricating oil exists and second passages 64, 68, 18a communicating with the inside area of the crankcase 24 where a small quantity of lubricating oil exists. The compressor further comprises an opening/closing valve 70 which increases the ratio of the first passages 12b, 12c, 62, 66, 68, 18a to the relief passage 62 by an increase in the rotational speed of a drive shaft 16 and a rise in the temperature inside the crankcase 24, and which increases the ratio of the second passages 64, 68, 18a to the relief passage 62 by a lowering in the rotational speed of the drive shaft 16 and a lowering in the temperature inside the crankcase 24.
