Title:
CONTROL VALVE FOR VARIABLE DISPLACEMENT COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/146389
Kind Code:
A1
Abstract:
Provided is a control valve for a variable displacement compressor that is capable of preventing foreign matter from accumulating in a gap between sliding surfaces that is formed between a main valve body and a guide hole, and as a result, is capable of making it less likely for operation failures such as valve locking or the main valve body leaving its position to occur. A lower end part of a sliding surface part 10f of (an intermediate fitting part 10c of) a main valve body 10, which enters an inward side of a sliding surface part 19f of a guide hole 19 when a valve orifice 22 is closed, is designed to protrude from the sliding surface part 19f of the guide hole 19 toward the valve orifice 22 when the valve orifice 22 is opened.
