Pressure regulator including a press-fit spring retainer

A pressure regulator, comprising:

• a housing defining an interior volume, the housing including:
• a first housing portion including an inlet;
• a second housing portion;
• and
• an outlet;
• a divider separating the interior volume into first and second chambers, the divider including:
• a first valve member;
• a diaphragm extending between the housing and the first valve member, fluid communication through the diaphragm being prevented;
• and
• a retainer securing the diaphragm relative to the first valve member, the retainer being press-fitted with respect to the first valve member;
• and
• a second valve member being arranged between first and second configurations relative to the first valve member, the first configuration substantially preventing fluid communication between the inlet and the outlet, and the second configuration permitting fluid communication between the inlet and the outlet.

A method of manufacturing a pressure regulator, the pressure regulator including a first valve element mounted in a housing having an inlet and an outlet, a second valve element movable with respect to the first valve element, and a divider separating the housing into first and second chambers and supporting the second valve element relative to the housing, a first configuration of the second valve element preventing a flow of fluid between the inlet and the outlet, and a second configuration of the second valve element permitting the flow of fluid between the inlet and the outlet, the method comprising:

• assembling the divider including:
• positioning a diaphragm with respect to the second valve element;
• and
• press-fitting a retainer with respect to the second valve element, the press-fitting including sandwiching the diaphragm between the second valve element and the retainer;
• mounting the divider in the housing so as to separate the first and second chambers.
