摘要
Apertures (A) through each face (B) of a planetary rotor, volutes (17) for low loss delivery and collection of fluid to and from the working volumes of a planetary rotary pump, compressor, or turbine, and zero clearance seals by using continuous carbon fiber reinforced polyetheretherketone (PEEK) or other self-lubricating materials significantly improve the volumetric flow rate of such rotary pumps compressors or turbines. By establishing a means to vent each working volume to an intake (15) or exhaust port (16) at arbitrary rotor positions, apertures linking working volumes to intake or exhaust ports allows each working volume of a multilobe planetary rotary pump to function independently near peak volumetric efficiency. An additional means to improve the performance of planetary rotary pumps has been established by using scroll-like volutes which collect and deliver the exhaust and intake flow for each working volume in a manner which reduces the fluid dynamic loss associated with conventional sudden expansions and contractions found at the inlet and exit of a plenum.
