CONTROL VALVE OF VARIABLE DISPLACEMENT COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2021/015116
Kind Code:
A1
Abstract:
This control valve has a communication channel that allows communication of two different pressure regions and that has a small cross-sectional area, wherein the communication channel can be formed more easily than in the prior art, whereby the cost of the control valve is reduced. In this control valve, a valve chamber (336) accommodating a valve body (341) is formed in divided sections by a valve body (311) and a fixed iron core (332) being joined together. Provided inside this control valve is a seventh communication channel (400) that bypasses a valve hole (315) and allows a refrigerant to flow to a crank chamber, the seventh communication channel (400) being formed by a fourth communication hole (401) formed in the valve body (311), and a first groove part (402) that is formed in a distal-end-side end surface (332b21) of the fixed iron core (332) and that constitutes an aperture that allows communication between the valve chamber (336) and the fourth communication hole (401) when the valve body (311) and the fixed iron core (332) are joined together.
