Appl. No.:

5/822168

Abstract:

An improvement in fluid filter bypass valve assemblies is disclosed in which bypassed fluid is discharged below the normal level of fluid in the assembly to avoid aeration of the by-passed fluid. The improved assembly includes a bypass valve structure comprising an elongated conduit communicating at one end with the high pressure side of the filter element and having a spring loaded sleeve slidably surrounding its free end. The free end of the conduit is normally sealed by the sleeve in cooperation with a flanged end cap but the sidewall of the free end of the conduit is provided with an aperture opening into a portion of the sleeve having enlarged internal dimensions so that fluid pressure higher than normal communicated through such opening into the sleeve will cause it to slide along the conduit against the spring loading and away from sealing engagement with the end cap to release fluid through the conduit. Preferred structural features of the bypass valve are described.

Abstract:

A control lever assembly including a single unitarily formed lever is mounted relative to an actuator such as a valve stem so that generally linear motion applied to one end of the control lever by an operator results in linear motion to the actuator generally at right angles to the linear motion applied to the control lever by the operator. Provision for dampening of unwanted vibratory motion is incorporated in the bracket arrangement mounting the control level.
