CONTROL VALVE FOR VARIABLE CAPACITY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2018/235482
Kind Code:
A1
Abstract:
This control valve used for a variable capacity compressor suppresses the infiltration of foreign substances into a slidable support part which slidably supports a valve unit including a valve part for opening/closing a valve hole. A valve body 311 of this control valve configured to suppress the amount of refrigerant, which is inside a discharge chamber and supplied to a control pressure chamber, has: a first port 320 through which the refrigerant inside the discharge chamber is introduced; a second port 321 through which the refrigerant inside the discharge chamber introduced through the first port 320 is discharged; a connection passage which connects the inlet port 320 and the outlet port 321 through a valve chamber 315 and a valve hole 316 open to the valve chamber 315; and a support hole 317 communicating with the valve hole 316. The support hole 317 slidably supports a valve unit 350 including a valve part 351 which opens/closes the valve hole 316. The first port 320 extends to the valve hole 316 and is inclined so as to approach a valve chamber 315-side opening of the valve hole 316 when going from the outer peripheral surface side of the valve body 311 toward a center line X.
