Abstract
A three component bypass valve comprises molded nylon valve body and poppet elements and a retained spring. The valve body includes an annular valve head having a valve seat therein and an integral open sided spring housing in the form of a pair of spaced tracks joined by an end wall. The tracks and end wall serve as a poppet guide and spring retainer, the poppet having notches for mating support surfaces, while the open housing allows pivotal movement of the poppet for ready assembly or replacement of the poppet and spring. The valve head is externally threaded for placement of the valve in a threaded bore of a fluid filter and the like.
