Document Type and Number:
Japanese Patent JP2022074857
Kind Code:
A
Abstract:
To provide a flow path switching mechanism enabling simple switching operation, and capable of suppressing intrusion of foreign matter.SOLUTION: A flow path switching mechanism 10 has an operating member 11 comprising a valve body 11a, and a housing 12 comprising a valve chamber 12a that houses the valve body 11a so that it can move forward and backward between a pressurizing position and a depressurizing position. The valve chamber 12a has an exhaust port 12b, an outflow port 12c, a connection port 12d, an inflow port 12e, and an intake port 12f. The valve body 11a is configured to communicate the intake port 12f with the inflow port 12e and the outflow port 12c with the connection port 12d at the pressurizing position, while communicating the connection port 12d with the inflow port 12e and the outflow port 12c with the exhaust port 12b at the depressurizing position. A filter member is provided upstream of the intake port 12f or at the intake port 12f.SELECTED DRAWING: Figure 9
