ABSTRACT:
A pressure regulator includes a housing, a divider including a first valve member, and a second valve member. The housing includes an inlet and an outlet, and defines an interior volume. The divider separates the interior volume into first and second chambers, and included the first valve member, a diaphragm, and a retainer. The diaphragm extends between the housing and the first valve member. Fluid communication between the first and second chambers through the diaphragm being prevented. The retainer secures the diaphragm relative to the first valve member, and the retainer is press-fitted with respect to the first valve member. The second valve member is arranged between first and second configurations relative to the first valve member. The first configuration substantially prevents fluid communication between the inlet and the outlet, and the second configuration permits fluid communication between the inlet and the outlet.
