Title:
FLOW PASSAGE SELECTOR VALVE
Document Type and Number:
Japanese Patent JP2017172773
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a flow passage selector valve capable of reducing an entire physical constitution or occupied space, reducing slide friction between a seal member and a valve body in flow passage switching, preventing the seal member or valve body from being worn, improving sealability, durability and certainty in flow passage switching, and employing a driving source with small output torque as a rotation driving source.SOLUTION: A flow passage selector valve includes: a valve body 10; a valve shaft 20 inserted into the valve body 10 to vertically move with rotation; a seal member 17 internally fitted to the valve body 10; and an elliptic plate-like valve element 30 that is disposed in a valve chamber 15 in a state of being inclined to a rotational axial line O of the valve shaft 20, whose outer peripheral end edge part is pressed against the seal member 17, and that in order to switch between communicating ports, is configured to be linked with the valve shaft 20 to vertically move with rotation. All ports are provided on a same plane including the rotational axial line O of the valve shaft 20 or on a same plane parallel with the above plane, and in flow passage switching of switching the communicating ports, an inclination angle to a rotational axial line O of the valve element 30 is made smaller than that before/after flow passage switching.SELECTED DRAWING: Figure 2
