ABSTRACT:
The unitary poppet valve assembly (50) comprises an annular retainer (52) having an open end (54) and an opposite end (55) with a small diameter opening (56) therein. The annular retainer (52) has a plurality of fingers (58) extending laterally therefrom for engagement with the body (12) of a proportioning valve assembly (10). A poppet (70) comprises a poppet head (72) extending radially outwardly from a longitudinal shaft (74), and an oppositely disposed abutment (76). The shaft (74) extends slidably through the small diameter opening (56) in the annual retainer (52), the abutment (76) engaging the retainer (52) adjacent the opening (56). A spring (60) is disposed between a corner or shoulder (57) of the annular retainer (52) and a shoulder (77) defined between the poppet head (72) and poppet shaft (74). The poppet (70) includes a central through opening (78) extending through the abutment (76) and to the head (72), wherein the opening (78) communicates with a lateral through opening (80) of the shaft (74). The unitary poppet valve assembly (50) may be inserted directly within an inlet opening (13) of the proportioning valve assembly (10) so that the fingers (58) engage the body (12) of the proportioning valve assembly (10).
