ABSTRACT:
A rotary displacer mechanism of the rotary-abutment type utilizes improved piston and sealing rotor design to reduce internal leakage and increase volumetric efficiency. A rotary-abutment positive displacement mechanism typically comprises a housing which encloses a rotary piston having a plurality of lobes and a cylindrical sealing rotor having a plurality of cavities for accepting the piston lobes during rotation. The improved piston design consists of a cylindrical stationary block around which only the lobes of the piston are rotatable. This design reduces bearing loads and allows for improved sealing characteristics. In addition, the sealing rotor is constructed with two axial sections of unequal diameter to provide a valving operation on either the intake or the discharge ports of the displacer, as required, and, at the same time, maintain communication between working volumes in the main rotor and sealing rotor bores. The design, by allowing the sealing rotor to perform the valving function, minimizes dead volume in the mechanism thereby increasing volumetric efficiency.
