Abstract: The fuel filter assembly of the present invention includes multiple tubes within a combination wash and barrier flow filter. The filter is designed to be used alternately between conventional wash flow mode and periodic barrier mode. The tubes are manufactured of a mesh or screen material. In wash flow mode, flow passes through the filter some of the fluid exits radially through the sidewalls of the tubes. The sidewalls filter particles out of the fluid and the particles blocked by the sidewalls are washed out the second end of the tube. In barrier mode, the motive flow is suspended and all of the potential contaminant is collected on the screen. Over time the screen will become increasing clogged and the pressure drop across the screen will increase. By adding additional tubes to the filter additional surface area of sidewalls is obtained without requiring an undesirable lengthening of the filter.

Abstract: An impact plate for use in a component having parts that move at high velocity, such as a piston or valve, controls energy transfer during impact of the moving part. The impact plate has a recessed inner portion that acts as an impact surface and an outer support surface to hold the impact plate within a housing of the component. The impact surface has a selected, controlled spring rate so that it can deflect and absorb impact forces when the moving part contacts it.

Abstract: A support structure for a C-ring includes a pair of circumferentially spaced holding members on catch plates. The holding members may be moved individually into the C-ring after the C-ring is mounted within an outer housing. The two holding members thus provide support to an inner periphery of the C-ring. A locking plate has support structure moved between circumferential ends of the housing members, thus providing effective support for the C-ring around its entire inner periphery. In this way, the two parts secured by the C-ring need not be moved relative to each other to insert the C-ring. The clearance or ability to move one of the two parts relative to the other which has been required in the past to mount a C-ring, is not necessary. This makes the inventive C-ring particularly useful for new applications, such as holding a porting sleeve within a valve housing.
