VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/157409
Kind Code:
A1
Abstract:
Provided is a valve device (100) which includes an operation shaft (50) switched between a connection state in which the operation shaft (50) is connected, as a result of a movement along a turn axis A1 of an operation pin (40), to the operation pin (40) so as to turn together with the operation pin (40) and a disconnection state in which the operation shaft (50) is not connected to the operation pin (40) and supports the operation pin (40) while allowing the operation pin (40) to turn. The operation pin (40) turns about the turn axis A1 by the turning of the operation shaft (50) about the turn axis A1 in the connected state, resulting in movement of a spool (20).
