Abstract

A filter assembly comprises a cover member detachably mounted on a stationary support and a support member attached to the cover member in axially spaced relationship therefrom. A tubular screen, having a filter disposed therein, is disposed axially between the cover and support member and defines an annular passage between it and the filter. In normal operation, fluid is communicated from an inlet, through the screen and filter and to an outlet. When the pressure of the fluid in the passages exceeds a predetermined level, the fluid is communicated from the inlet and through the screen and passage to open a bypass valve mounted in the cover to communicate the fluid directly to the outlet. A plurality of magnets are preferably secured on an underside of the support member and adjacent to the inlet to uniformly disperse the fluid thereby and to pick up metallic contaminants.
