弁。A four-way switching valve for opening and closing the door that can alternately switch the supply and discharge of pressure fluid to each chamber of the double-acting cylinder that opens and closes the door, and controls the supply of pressure fluid from the pressure source to the four-way switching valve. It is interposed between the manual switching valve for the pressure source, and when the manual switching valve is switched from the exhaust position to the air supply position, the pressure on the four-way switching valve side remains unchanged until the pressure on the four-way switching valve side reaches a predetermined value. In a flow rate limiting valve for a door opening/closing device that limits the supply speed of pressure fluid and allows the free supply of pressure fluid to the four-way switching valve when the supply speed exceeds the predetermined value, the flow rate limiting valve is provided within the valve body, A first and a second valve are connected to the manual switching valve through an input hole.
a valve hole that communicates with the four-way switching valve through an output hole; a valve hole that is slidably inserted into the valve hole;
a valve body having a communication passage formed in the internal axial direction to connect with the output hole of the valve body; a sheet surface that can be cut off between the first output hole and the first output hole;
a preload spring that urges the valve body in the direction of seating on the valve seat; A flow rate limiting valve for a door opening/closing device, comprising an output hole and a throttle member that narrows a passage.
