Summary

A NEW DESIGN SOLUTION FOR A HERMETICALLY-SEALED ROTARY COMPRESSOR IS PRESENTED, AND ESSENTIAL DIFFERENCES BETWEEN IT AND A ROLLING PISTON COMPRESSOR ARE EXPLAINED. INNER GAS TIGHTNESS IN THE LATTER CAN BE ATTAINED ONLY BY EXTREMELY HIGH PRECISION IN PRODUCING INDIVIDUAL COMPONENTS. MOREOVER, IT IS VERY NOISY, AS IT IS IMPOSSIBLE TO FULLY BALANCE THE VANE MOTION AND THE VARIABILITY OF MOMENTUM. THE NEW CONCEPT FEATURES A ROTATING VANE WITH A CRESCENT-FORMED VANE, WHICH IS CONSTANTLY PRESSED BETWEEN THE INNER-FACE AREAS OF THE SHAFT ONTO THE PERIPHERAL PISTON SURFACE BY A THRUST SPRING. THE ROTATIONAL MOTION REPLACES THE FORMER AXIAL MOTION OF THE VANE OUTSIDE OF THE PISTON WORKING SPACE. THE MERITS OF THE NEW SOLUTION ARE EXPLAINED.
