FIELD: engines and pumps.SUBSTANCE: invention relates to rotary engines, pumps and compressors. Rotary assy comprises stator to make, in fact, oval chamber and rotor to run in said chamber on central shaft to confine, along with said stator, the two cavities at chamber opposite ends. Rotor grooves house vanes to slide in radial direction. First and second primary rollers and first and second secondary rollers are fitted at every said vane. First rollers are fitted at first side edge of the vane. Second rollers are arranged at opposite side edge. Stator sidewalls have two cam-and-roller devices to make primary and secondary curvilinear surfaces intended for adjustment of vane radial displacement and composed inside said cam-and-roller devices. Curvilinear surfaces are axially offset relative to each pother and radially - relative to axis of revolution.EFFECT: efficient adjustment of cane radial displacement, simple and cheap design of the rotor.20 cl, 19 dwg |
