Title:
流体分配バルブ並びにこれを備えた流体供給システム及びその制御方法
Document Type and Number:
Japanese Patent JP5543608
Kind Code:
B2
Abstract:
[Object] Without requiring a plurality of fluid supply sources such as a pump device and the like, a fluid can be selectively supplied relative to at least two or more fluid supply routes by a simplified structure. [Means of Solving Problem] A fluid distribution valve includes first and second branch pipes communicated with a washer pump; and a valve body selectively closing either one of two branch pipes, and including a through hole allowing a circulation of the fluid into the second branch pipe from the washer pump in a case wherein the first branch pipe is closed. While the valve body closes the first branch pipe in an initial state thereof, the valve body is displaced or deformed according to a pressure difference of the fluid in a first branch pipe side and a second branch pipe side when the fluid is supplied from a washer pump source so as to open the first branch pipe, and to close the through hole.
