Abstract
In at least some implementations, a pressure regulator includes a first body, a second body coupled to the first body and a diaphragm having a portion trapped between the first body and the second body and a not trapped portion that is movable relative to the first body and second body. A stop surface is defined by the second body, and a backing member is coupled to the not trapped portion of the diaphragm for movement with the not trapped portion of the diaphragm. The backing member engages the stop surface to limit the amount the not trapped portion of the diaphragm can move toward the second body.
Claims19
A pressure regulator, comprising:
- a first body;
- a second body coupled to the first body;
- a diaphragm having a portion trapped between the first body and the second body and a not trapped portion that is movable relative to the first body and second body;
- a stop surface defined by the second body;
- a backing member coupled to the not trapped portion of the diaphragm for movement with the not trapped portion of the diaphragm, wherein the backing member engages the stop surface to limit the amount the not trapped portion of the diaphragm can move toward the second body.
A pressure regulator, comprising:
- a first body including a groove having an inner side surface, a bottom surface and an outer side surface and the bead is engaged with the bottom surface and the outer side surface;
- a second body coupled to the first body;
- a diaphragm having a portion trapped between the first body and the second body and a not trapped portion that is movable relative to the first body and second body, the portion trapped between the first body and the second body includes a bead received at least partially within the groove;
- a pressure chamber defined at least in part between the first body and the not trapped portion of the diaphragm.
