Title:
FLUID ENERGY TRANSFER DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/022770
Kind Code:
A3
Abstract:
A rotary chambered fluid energy-transfer device includes a housing with a central portion having a bore formed therein and an end plate (414) forming an arcuate inlet passage (415), with a radial height and a circumferential extent. The device also includes an outer rotor (120) rotatable in the central portion bore with a female gear profile formed in a radial portion defining a plurality of roots (424) and an inner rotor (440) with a male gear profile defining a plurality of lobes (449) in operative engagement with the outer rotor (420). A minimum radial distance between an outer rotor root (424) and a corresponding inner rotor lobe (449) define a duct end face (441) proximate the end plate (414), wherein the duct end face (441) has a radial height substantially equivalent to the inlet passage (415) radial height at a leading edge (480) of the inlet passage (415).
