Document Type and Number:
WIPO Patent Application WO/2021/205800
Kind Code:
A1
Abstract:
This flow path switching valve facilitates the formation of a flow path to the body, can be manufactured at a low cost, and is able to be made compact. The flow path switching valve 50 comprises: a block-shaped body 51 having a first opening 61 and a second opening 62 which communicate with each other via a linear first oil path 71, and a third opening 63 which communicates with the first oil path 71 via a linear second oil path 72; a valve body 52 which is provided so as to be rotatable relative to the body 51, and in which a communication flow path is formed that allows two openings to communicate with each other depending on the rotation position; and a locking protrusion 110 which regulates the rotation range of the valve body 52 in order to select the rotation position of the valve body 52 to be a predetermined rotation position where two openings of a predetermined combination among the three openings communicate with each other via the communication flow path of the valve body 52.
