HYDRAULIC VALVE WITH A FILTER AND CHECK VALVE BAND |
摘要 |
An hydraulic valve has a body with an exterior surface, a longitudinal bore, and first and second fluid ports in communication with the bore wherein the first fluid port opens through the exterior surface. A band is wrapped in first and second layers around the exterior surface which layers extend over the opening of the first fluid port. The first layer has a plurality of apertures there through and overlaying the opening to provide a filter. The second layer has a flap that flexes in response to pressure to open and close the plurality of apertures thereby acting as a check valve. An actuator slides a spool within the bore thereby selectively connecting and disconnecting the first and second fluid ports.
