CAPACITY CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2019/131482
Kind Code:
A1
Abstract:
Provided is a capacity control valve with which it is possible, during startup of a variable-capacity compressor, to quickly reduce the pressure in a control chamber. A capacity control valve V is provided with: a valve housing 10; a main valve body 53 which has a main valve part 53a that comes into contact with and separates from a main valve seat 12c, and which opens and closes communication between a discharge port 12a and a control port 14a due to the driving force of a solenoid 80; a relief valve 59 opened by pressure; a first flow channel 56 through which the control port 14a and an intake port 13a communicate due to the opening of the relief valve 59; and a second flow channel 90 through which the control port 14a and the intake port 13a communicate; wherein the capacity control valve V has a spool valve body 52 that is disposed within a sleeve 83s so as to be able to reciprocate and that switches the communication of the second flow channel 90, and after the main valve part 53a has come into contact with the main valve seat 12c, the spool valve body 52 moves further due to the driving force of the solenoid 80 and widens the opening degree of the second flow channel 90.
