A rotary vane machine with a cam track and vane mechanisms

摘要

The invention relates to a rotary vane machine (1) for fluid processing, comprising a housing (2) with an internal wall (3); a rotor (20); a cam track (40); and vane mechanisms. Each vane mechanism comprises a cam follower (42); a radial guide (50) for cam follower (42); a vane shaft (31); a vane (30) and a crank (41) which both are rigidly connected to vane shaft (31); and a connecting rod (60) pivotally connected to crank (41) and cam follower (42). During rotation, cam follower (42) follows cam track (40), and the movement of cam follower (42) is transferred through the vane mechanism to a sealing portion (35) of vane (30), which seals against housing internal wall (3).
