VARIABLE DISPLACEMENT OSCILLATING COMPRESSOR

Japanese Patent JPH01182580

A

PURPOSE:To improve a cool-down characteristic by connecting a crankcase to a suction chamber with a plurality of connecting passages each having a control valve mechanism, differentiating the opening/closing operating points of one control valve mechanism, and setting the operating point of the other control valve mechanism between the opening/closing operating points. CONSTITUTION:A first connecting passage 17 for connecting a crankcase 10 to a suction chamber 14 is controlled in its opening/closing by means of a first control valve mechanism 16. As the pressure of the crankcase 10 is regulated by means of the first control valve mechanism 16, the inclination angle of an oscillating board, etc. is varied to control the pressure of the suction chamber 14. In this structure, a second connecting passage 19 for connecting the crankcase 10 to the suction chamber 14 is provided and a second control valve mechanism 18 is provided in the second connecting passage 19. In the second control valve mechanism 18, the operating point at the time of valve closing is set lower than the operating point at the time of valve opening. The pressure controlling point for the suction chamber 14 of the first control valve mechanism 16 is set between the operating points of the second control valve mechanism 18.
