FIELD: machine building.SUBSTANCE: pressure regulator comprises a casing with inlet and outlet holes and a flange connected to the casing by screws. A membrane dividing the pressure regulator cavity into fuel and air chambers is fixed in the junction place. The pressure regulator also comprises a lower plunger and an upper plunger coupled with the membrane, a spring with a threaded cup to adjust the action force of the lower plunger on the inlet hole seat. The casing is fitted by vertical inlet and outlet holes connecting the inlet and outlet holes to the fuel chamber and to the pressure measuring sensors and fuel temperature measuring sensors. For the purpose of adjusting the conjugation of the seat and the lower membrane's plunger, the seat inlet hole and the mating supporting part of the lower plunger are of conical shape, the side casing surfaces are fitted by additional outlet holes to feed one or more units.EFFECT: increased reliability and stability of pressure regulator work and expanded functionality.2 dwg |
