Title:
CONTROL MECHANISM FOR CRANK CHAMBER PRESSURE IN SWINGING SWASH PLATE TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JPS62240482
Kind Code:
A
Abstract:
PURPOSE: To obtain a compression capacity according to a cooling load, by providing a control valve for controlling a restriction of a relief passage communicating a crank chamber with a suction chamber.
CONSTITUTION: A control valve 29 is provided in a rear housing 3 to control the pressure in a crank chamber 13. A control valve 41 is provided in blow-bay gas relief passages 28A and 28B communicating the crank chamber 13 with a suction chamber 6. A communication passage 42 is variably restricted by the control valve 41. Accordingly, an inclined angle of a wobble plate 21 may be varied with a little amount in a swing direction according to a reduction in cooling load, thereby obtaining a desired compression capacity.
