Patent ID: 7131457

Claim:
A flow-through pressure regulator, comprising: a housing having an inlet and an outlet spaced along a longitudinal axis from the inlet; a divider separating the housing into a first chamber and a second chamber, the divider including: a seat defining a passage between the first and second chambers, fluid communication between the first and second chambers through the passage being permitted; a diaphragm extending between the housing and the seat, fluid communication between the first and second chambers through the diaphragm being prevented; and a retainer securing the diaphragm relative to the seat, the retainer including: a cylindrical portion extending about the longitudinal axis and being fixed with respect to the seat; and an axial end portion extending from to cylindrical portion and extending generally orthogonal relative to the longitudinal axis, the axial end portion including a plurality of apertures, fluid communication between the passage and the second chamber through the plurality of apertures being permitted; and a closure member being arranged between first and second configurations relative to the seat, the first configuration substantially preventing fluid communication through the passage, and the second configuration permitting fluid communication through the passage.
