Abstract
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.
