摘要： A fluid pressure regulator includes a regulator housing having an inlet end and an outlet end; a flexible flow tube extending between the inlet end and the outlet end; a hollow piston located at a downstream location relative to a mid-portion of the flow tube in a direction of flow of fluid through the regulator housing; a first chamber above the piston and a second chamber below the piston; a passage establishing fluid communication between the outlet end and the first chamber; and at least one pinch arm pivotally mounted at one end within the regulator housing and movable in response to movement of the piston by an increase in fluid pressure in the first chamber so that an opposite end of the at least one pinch arm will pinch a portion of the flow tube and thereby restrict flow through the flow tube.

摘要： A fluid pressure regulator comprising a tubular housing having a fluid inlet at one end thereof and a fluid outlet at an opposite end and a fluid passage therebetween; a tubular plunger mounted for reciprocal movement in the fluid passage, the plunger having a flow control end and a piston end; a seat in the fluid passage including a seating surface located axially upstream of the plunger and adapted to be approached or engaged by a lower edge of the flow control end of the plunger, the seat supported centrally within the fluid passage by a single radially-oriented strut.
