FIELD: mechanical engineering, compressor engineering.
SUBSTANCE: the technical solution relates to mechanical engineering, namely to compressor engineering. The valve body (valve box) can be used in the design of the upper stages of two- or four-row opposed piston multistage compressors. The valve body of a multistage compressor contains a central non-through hole with a variable diameter, made with the possibility of installation on the cylinder liner of a reciprocating compressor, and two valve non-through holes with a variable diameter, made with the possibility of placing suction or discharge valves in them. The central hole communicates with the valve holes, the axes of the valve holes are located at right angles to the axis of the central hole.
EFFECT: reducing the overall dimensions of a multi-stage compressor, facilitating the installation and maintenance of the compressor due to increased gaps between the structural elements of the compressor and the side walls of the shelter.
