FLOAT CHAMBER OF OIL-SUPPLYING SYSTEM OF NATURAL GAS COMPRESSOR Russian patent published in 2009 - IPC F04D29/63 

FIELD: mechanical engineering.

SUBSTANCE: in float chamber of oil-supply system of natural gas compressor, containing casing with inlet and outlet branches, gas withdrawal branch, sluice in the form of valve, installed on outlet branch with valve, spring-loaded into the side of opening and gauge tube, according to the invention, into gauge tube it is installed hollow element with resilient walls, implemented from two plates, at least one of which allows convexity, and waterproof connected to each other, with damping walls from pressure of oil, weight and volume of hollow element are defined from condition: P=V_H×γ, where: P - weight of hollow element ; V_H - volume of hollow element at working pressure of oil; γ - specific weight of oil.

EFFECT: simplification of control of level and pressure of oil in chamber and reliability growth of compressor.
