Abstract:
1. A combined spring and poppet assembly incorporated into a valve housing which communicates with a fluid inlet and outlet, said assembly comprising: an elongated, three dimensional shaped and resilient one piece body positioned in linearly displaceable fashion within the valve housing and along a path established between the fluid inlet and outlet; the valve housing having a specified shape and size and further having a plurality of interiorly disposed threads associated with a selected interior location which rotatably interengage a further plurality of exteriorly disposed threads associated with a location of said elongated body to vary a selected spring pressure; said body exhibiting a substantially cylindrical shape and including a forward-most poppet, seating against the fluid inlet, a plurality of flow apertures being defined along circumferentially spaced and intermediate locations associated with said poppet and such that, upon unseating of said poppet from the inlet, the fluid flowing through an open interior of said body to communicate said inlet with said outlet; and said one piece body further comprising an integral spring biasing portion being located intermediate said forward-most located poppet and said exteriorly disposed threads so that, upon a pressure in the fluid inlet exceeding a predetermined value, said poppet being caused to unseat from the inlet and to displace linearly and in compressing fashion against said integral spring portion concurrent with fluid flow across the outlet.
