A pressure regulator including a press-fit spring retainer

A pressure regulator (100) includes a housing (12,14), a divider including a first valve member (36), and a second valve member(64). The housing (12,14) includes an inlet (24) and an outlet (24), and defines an interior volume (52,54). The divider separates the interior volume into first (52) and second chambers (54), and includes the first valve member (36), a diaphragm (40), and a retainer (34). The diaphragm (40) extends between the housing (12,14) and the first valve member (36). Fluid communication between the first (52) and second chambers (54) through the diaphragm (40) is prevented. The retainer (34) secures the diaphragm (40) relative to the first valve member (36), and the retainer (34) is press-fitted with respect to the first valve member (36). The second valve member (64) is arranged between first and second configurations relative to the first valve member (36). The first configuration substantially prevents fluid communication between the inlet (24) and the outlet (18), and the second configuration permits fluid communication between the inlet (24) and the outlet (18).
