摘要： Provision of constrictions imparts to a sealing ring for spool valves both needing flexibility and sufficient strength to remain undetached from the spool in the spool valves. The constrictions to impart flexibility are provided on the outside of the center of the band width of the sealing ring. The ring is of a greater axial thickness on a radially inner side thereof than at the constrictions so as to be firmly fitted in a groove of the spool.

摘要： A pilot-type two-port valve is disclosed having a water hammer preventing mechanism, operative to prevent a water hammer during valve-closing operation, which includes a valve member operative to open or close a valve and a piston driven by pilot fluid for operating the valve member for opening and closing movements. The water hammer preventing mechanism comprises a piston drive chamber, from which fluid is discharged during valve-closing operation, which has an orifice for restricting the flow rate of discharge fluid whereby when the piston moves to a position to allow the valve member to be close to a valve seat, a portion of an discharge flow passage of the piston drive chamber is blocked to restrict the flow rate of the discharge fluid to the flow rate of fluid flowing through the orifice.
