FIELD: machine building.

SUBSTANCE: regulator includes a housing with inlet and outlet cavities and between them a spring-loaded sensitive element in the form of a shell, a setting cavity with an elastic element, a seat, a shutoff element in the form of a disc with a conical surface. The housing is made of two halves in the form of bowls with flanging, and in it there introduced and installed with stiff connection is a cylinder with the above mentioned shell located in it with outer surface of the bottom towards the seat installed in the inlet cavity.
