FIELD: machine building.
SUBSTANCE: invention relates to the field of mechanical engineering, in particular to the arrangement of the distribution bodies of volumetric displacement machines. Valve assembly of the piston machine consists of liner (2) with piston (3) mounted in body (1), which interacts with end face (4), spring-loaded pressure valve (5) and spring-loaded suction valve (6). Suction valve (6) is provided with radial holes (13) for passing the working medium from inlet duct (14) to working chamber (15).
EFFECT: technical result consists in increasing the convenience of installation and maintenance, reliability and durability through the use of a modular, modular valve assembly design.
