Abstract

Abstract The rotary closed series cycle engine system is a rotary version of the latest type of series or double-acting reciprocating Stirling cycle engine. Identical rotary units are mounted in a tandem arrangement with each unit providing the displacement function for an adjacent unit, in a series gas flow loop. Thermal transfer is greatly improved by the application of a large number of small transfer tubes in a high external loop with separation between the hot and cold sources. Since the rotary unit has non-contacting vanes, friction is kept to a minimum while the compression ratio is moderately high. Hydrogen gas is the fuel for the system which is obtained from an electrolysis unit with a wind generator, operating on a continuous demand controlled basis.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 329 words
A rotary closed series cycle engine comprising multiple indentical rotary units consisting of rotors and vanes revolving within cylindrical housings, two identical end plates secured to the ends of said cylindrical housings including concentric circular grooves uniformly disposed on the inside faces of said end plates, a uniformly slotted rotor eccentrically and tangentially disposed within said cylindrical housing, multiple flat and hollow rectangular vanes in sliding communication with the slots of said uniformly slotted rotor, multiple ball bearings secured to each side of said multiple flat and hollow rectangular vanes by means of multiple cylindrical pins, said multiple ball bearings are in rolling contact with said concentric circular grooves uniformly disposed on the inside faces of said end plates, two low-friction discs disposed on either side of said uniformly slotted rotor between said two identical end plates, a drive shaft concentrically disposed through said uniformly slotted rotor supported by two needle bearings eccentrically disposed within each of said two identical end plates, multiple gas pressure seals disposed on the outer faces of each of said two identical end plates over said drive shaft, four outer mounting brackets secured to the outer surface and ends of said cylindrical housing, four spacers disposed adjacent to said four outer mounting brackets fastened by four mounting screws and nuts, standard fastening and sealing means utilized for joining and securing components of said rotary closed series cycle engine, identical gas flow manifolds secured at the sides of said cylindrical housings, two rectangular ports disposed at the upper sides of said cylindrical housings in direct communication with said gas flow manifolds, multiple small diameter transfer tubing connected from one lateral group of said gas flow manifolds to the opposite lateral group of gas flow manifolds on adjacent rotary units of said rotary closed series cycle engine, joining and sealing means for said gas flow manifolds to said cylindrical housings, joining and sealing means for said multiple small diameter transfer tubing to said gas flow manifolds.
