ABSTRACT:
A plastic relief valve assembly is provided having a one-piece valve body, with a sleeve portion and a slotted portion, and a valve. The slotted portion includes a plurality of radially disposed inlets. The valve includes an axial portion and a radial portion. The radial portion extends angularly over the radial inlets in a seated position and the axial portion extends into the valve body for quick connection therewith by a groove and rib combination provided on the valve and valve body, respectively. The radial portion of the plastic valve is flexible, and the valve opens when fluid pressure reaches a predetermined level. A plastic antidrain valve is also connected to the valve body. A fluid filter incorporating the combined plastic relief valve assembly/antidrain back valve is also provided.
