Abstract
The fuel supplied to an injector is maintained at substantially constant pressure by a fuel pressure regulator which balances the fuel pressure with the bias of a coil spring. To establish the desired pressure, a spring housing is deformed to move a spring seat to the position which causes the spring to exert the required bias. The spring seat is connected to the diaphragm by a tie rod which simplifies assembly of the pressure regulator. Slits in the outer portion of the diaphragm allow separation of the diaphragm along an arcuate line while maintaining a continuous peripheral seal about the pressure regulator.
