SLIDING-VANE ROTARY COMPRESSOR Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used for compressing and building of vacuum in different industries. Proposed sliding-vane rotary compressor contains housing accommodating main chamber consisting of cylinder of end face covers enclosing rotor, cylindrical distributor, additional working medium compression chambers arranged on part of rotor length and formed by distributor installed on posts, and rotor with slots and separating plates and spaces made opposite to each plate. Housing is furnished with cooling jacket. Covers are installed in housing for rotation. Cylindrical surface of distributor of posts is arranged coaxially relative to end face cover cylinder. Coaxial holes for shaft are made in posts. End face covers are provided with radiator and bushing installed coaxially relative to cylinder of end face covers. Bushing, together with post distributor is located on part of rotor length. In spaces of rotor counterweights are installed which are connected by tie-rods with each separating plate. Housing is provided with ports and oil trap, and one of posts is provided with piston disk. Rotor spaces are placed in communication with slots by channels. Slots have longitudinal grooves. Rotor spaces communicate through channels made in shaft and rotor with lower level of oil trap reservoir. Piston space of post and its distributor space also furnished with piston disk communicate through channel with delivery channel of corresponding chamber, being made with possibility of axial pressing of end face covers and post distributor to rotor at its rotation. Cylindrical surfaces of end face covers pointed to distributors are provided with seals, for instance, end face seals. EFFECT: increased delivery pressure, reduced power consumed at compression. 8 dwg, 14 dwg
