Document Type and Number:
Japanese Patent JP6656859
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a flow passage selector valve that can reduce slide resistance to a seal member (rubber material) to effectively reduce torque required for switching a flow passage while securing mechanical strength of a valve body.SOLUTION: In the flow passage selector valve, an outer side in a cylindrical valve element part 22 of a valve body 20 is formed of a material having a lower slide resistance to the seal member 30 than that of the inner side thereof. In the cylindrical valve element part 22, an outer side of a cylindrical body part 25 is formed by being covered with a cylindrical cover part 27 formed of the material having a lower slide resistance to the seal member 30 than that of the cylindrical body part 25.SELECTED DRAWING: Figure 2
