A fluid pressure regulator is disclosed including a valve body and a control body sealed within a tubular outer housing. The valve body has a supply chamber and an output chamber separated by a valve wall. A valve rod extends through the valve wall with a seal unit therebetween for selectively connecting a passageway associated with the valve rod between the supply chamber and the output chamber. The output chamber has a movable wall connected to the rod. A control chamber is secured within the tubular housing in spaced relation to said movable wall with the space between the movable wall and the control chamber connected to atmosphere. The control chamber has a control rod with an adjustable bias spring urging the rod outwardly into engagement with the movable wall. A balance pressure passageway is formed by a lateral passageway from the supply chamber and from the control chamber with a passageway formed between the bodies and the tubular housing to connect said lateral passageway and maintain both chambers at the same pressure. The rod is formed in association with a movable sealing wall and seal member to provide various passageway constructions.
A pressure regulator for maintaining an output pressure with varying input pressure comprising a valve assembly including a supply chamber and an output chamber separated by a valve unit, said output chamber having a movable wall, said valve unit including a valve passageway between said supply chamber and said output chamber and a movable valve member connected to said movable wall and operable to open and close said valve passageway, a control unit located adjacent said valve assembly and including a pressure control chamber including a control member within said pressure control chamber and connected to said movable wall and resiliently biasing said movable wall to place said movable valve member to open said passageway, and said output pressure being operable to reset said movable wall and said control member to close said valve passageway, and said control chamber and said supply chamber being connected to the supply to establish a corresponding balancing pressure in said control and supply chambers.
A pressure regulator for maintaining an output pressure with varying input pressure and/or a minimum output flow from the regulator, comprising a valve assembly including a supply chamber and an output chamber separated by a valve unit, said output chamber having a movable wall, said valve unit including a valve passageway between said supply chamber and said output chamber and a movable valve member connected to said movable wall and operable to open and close said valve passageway, a control unit located adjacent said valve assembly and including a pressure control chamber including a control member within said pressure control chamber and fixedly connected to said movable wall and resiliently biasing said movable wall to place said movable valve member to open said passageway, and said output pressure being operable to reset said movable wall and said control member to adjust the opening of and to close said valve passageway.
