Abstract:
A pressure regulator, comprising:a fixed, hollow, seat retainer; and a movable seat disposed within the hollow seat retainer to control fluid flow through the pressure regulator, the seat having a plurality of outwardly projecting polymeric portions adapted to slidingly engage an interior surface of the hollow seat retainer to define a fluid passageway between the scat and an interior surface of the hallow seat retainer and to produce friction between the scat and the interior surface of the seat retainer to dampen movement of the seat; wherein fluid is free to flow through the pressure regulator via the fluid passageway to raise fluid pressure downstream of the pressure regulator in a first position of the seat, further wherein fluid is blocked from flowing downstream via the fluid passageway in a second position of the seat.
