MULTIFUNCTIONAL PRESSURE REGULATOR Russian patent published in 2014 - IPC G05D16/00 

FIELD: machine building.

SUBSTANCE: pressure regulator comprises a body provided with a cylindrical guide and inlet and outlet chambers, a gating assembly with a rod made to provide a possibility of sliding along a cylindrical guide for closing the seat opening, a stopping mechanism made to provide a possibility of movement to close the outlet chamber, a gate travel limiter, a membrane assembly controlling the gate and an assembly controlling the stopping mechanism. In this case the pressure regulator comprises the first noise-reducing element located in the calibrated passage and attached to the gate, the second noise-reducing element located in the body outlet chamber, a gate displacement damper assembly located between the gate travel limiter and the gate control membrane assembly. The gate control assembly corresponds to a chamber divided into two cavities by means of a membrane, which centre is attached to a gate rod.

EFFECT: extending functional capabilities of the device, increasing accuracy of retention of the output pressure values.
