Title:
VARIABLE CAPACITY TYPE SWING PLATE TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JPS61283774
Kind Code:
A
Abstract:

PURPOSE: To arbitrarily control the suction pressure and control the discharge capacity for coolant when a compressor is in operation, by controlling a valve body which opens and closes a communication passage between a suction chamber and a crank member and has a pressure receiving surface for receiving the pressure in the suction chamber, according to an external signal.

CONSTITUTION: When a heater 65 is turned-ON to heat the sealed gas-liquid mixed material 69, the pressure of the sealed gas-liquid mixed material increases, and the surface force of the pressure receiving surface 61d of a valve body 61 X the pressure of the sealed gas-liquid mixed material increases, and the urging force of the valve body 61 towards the valve closing side increases. Therefore, the valve opening pressure of the valve body 61 of a pressure adjusting valve 60 increases, and the pressure in a suction chamber 41 increases, and the discharge capacity of a compressor can be controlled finally. Therefore, the discharge capacity of the compressor can be controlled by turning-ON or OFF the heater 65.
