Title:
DISPLACEMENT CONTROL STRUCTURE IN CLUTCHLESS VARIABLE DISPLACEMENT TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JP3175536
Kind Code:
B2
Abstract:
PURPOSE: To obtain a simple and a low cost of displacement control structure of a clutchless compressor.
CONSTITUTION: A pressure feeding passage 31 to connect a discharge chamber 3-2 and a crank chamber 2-1 is opened and closed by a solenoid valve 20. The discharge chamber 3-2 and the crank chamber 2-1 are connected by the pressure feeding passage 31. The solenoid 32 of the solenoid valve 20 receives the exciting and the demagnetizing controls of a control computer C1 through a driving circuit 55. The control computer C1 controls the input current value to the solenoid 32 depending on the detecting temperature data obtained from a temperature sensor 39. The control computer C1 instructs the input current value to the driving circuit 55 depending on the detecting temperature obtained from the temperature sensor 39. The driving circuit 55 outputs the instructed input current value to the solenoid 32.
