REFRIGERANT INFLOW PREVENTING STRUCTURE IN COMPRESSOR

Japanese Patent JP3687129

B2

PURPOSE: To prevent wearing and seizure in a lubrication necessary part in a compressor when it is started.
CONSTITUTION: A pressure supply passage 31 of connecting a delivery chamber 3-2 and a crank chamber 2-1 is opened/closed by a solenoid opening/closing valve 32. A spool valve 20 is interposed on the pressure supply passage 31 between the solenoid opening/closing valve 32 and the crank chamber 2-1. A suction passage 26 of introducing a refrigerant from an outside refrigerant circuit 35 to a suction chamber 3-1 is opened/closed by an interrupter 21 associated with a swash plate 15. When operating a compressor is stopped, the solenoid opening/closing valve 32 is opened, and the interrupter 21 closes the suction passage 26 with a tilt angle of the swash plate 15 making a minimum tilt angle. The spool valve 20 is arranged in a position of closing the pressure supply passage 31 by tension of a compression spring 45.
