DIRECT-FLOW VALVE OF PISTON COMPRESSOR Russian patent published in 2014 - IPC F16K15/16 

FIELD: machine building.

SUBSTANCE: direct-flow valve of a piston compressor comprises a valve board in the form of a disc, in which in the perpendicular plane there are inlet and outlet channels and stop elements between them. In the disc there is a circular peripheral collar for its fixation in the compressor cover. The disc is made from an elastic heat resistant material. Inlet and outlet channels are made in the form of coaxial cylindrical holes. Each stop element is made in the form of two diametrically closed grips in the closed position, which are in the outlet channel and are cast as integral with the body of the disc in their base. Axes of channels are evenly arranged on concentric circumferences along the entire area of the disc. In the body of the disc there is a reinforcing metal plate protruding into the circular collar with holes that surround inlet channels.

EFFECT: reduced hydraulic resistance of a valve during gas flow, which results in reduced consumption of energy consumed by an electric engine of a piston compressor.
