  • Pressure regulating valve with integral damping
    Patent number: 6289919
    Abstract: A valve (20B) is provided is provided for regulating the pressure differential between a high pressure side (16) and a low pressure side (18) of a fluid system component (14). The valve (20B) utilizes a damping washer (60) to restrict the flow of fluid from a valve bore (32) in response to translation of a valve spool (30) in the valve bore (32). The damping washer (60) includes an aperture (78) that is piloted on a valve stem (41) extending from the valve spool (30). The damping washing (60) is biased against an open end (66) of the valve bore (32) by a spring (62) engaged between the damping washer (60) and a spring seat (48) that is engaged with the valve stem (41). A separate spring (46) is provided to bias the valve spool (30) against the high pressure fluid acting on the valve spool (30).
