MULTI-WAY VALVE
Document Type and Number:
WIPO Patent Application WO/2023/045316
Kind Code:
A1
Abstract:
A multi-way valve, comprising a valve seat (20) and a valve core (10). The valve core (10) is rotatably arranged on the valve seat (20); the valve seat (20) is provided with a plurality of valve port groups, each of which comprises a plurality of valve ports; and the valve core (10) is provided with conduction structure groups corresponding to the valve port groups, each conduction structure group comprising a plurality of conduction structures arranged in a circumferential direction. When the valve core (10) rotates to different rotation positions, the valve ports in the different valve port groups form different conduction states. Only one valve core (10) is needed to achieve different conduction states formed by a two-way proportional valve, a three-way proportional valve and a four-way proportional valve, thereby achieving simple control, a compact structure, and a low cost.
