FLOW PATH SWITCHING VALVE

Title:

FLOW PATH SWITCHING VALVE

Document Type and Number:

WIPO Patent Application WO/2020/110840

Kind Code:

A1

Abstract:

A flow path switching valve is provided which, by increasing the rigidity of a high pressure-side valve body of a slide valve body, can suppress seal surface distortion and prevent valve leakage, and which improves efficiency of a heat pump-type heating and cooling system. In this flow path switching valve (1), on the opposite inner peripheral surfaces of a high pressure-side slide valve body (15A), a bridging part (19) is provided which connects the inner peripheral surfaces which face each other in the direction perpendicular to the axial direction of a main valve chamber (12). For that reason, it is possible to increase rigidity of the high pressure-side slide valve body (15A), and seal surface distortion can be suppressed even if a high pressure refrigerant flows and applies a high pressure to the high pressure-side slide valve body (15A). Consequently, it is possible to suppress valve leakage in the flow path switching valve (1), and further, increased efficiency of the heat pump-type heating and cooling system (100) is achieved.
