ABSTRACT:
A pressure regulator valve for use in fuel systems for internal combustion engines which includes a two-part housing lamination with a diaphragm between the bottom and top housings and a centering valve guide disc above the diaphragm. The diaphragm is responsive to fuel pressure and will open a valve to by-pass fuel to a fuel tank. The centering valve guide disc functions to locate a diaphragm backing disc above the valve seat. A preferred diaphragm is formed of thin metal such as stainless steel which is confined at its periphery by housing elements to avoid destructive deformation in maximum pressure testing. In another embodiment, the metal operating diaphragm is secured at its periphery and formed in a manner to react in response to pressure to counteract increased spring force of a diaphragm backing spring. A press-in spring cap or cup allows calibration of the unit during assembly with a strike-in to fix the calibration in a tamperproof structure.
