Abstract

Abstract A new type of engine, which incorporates rotors each equipped with a plurality of vanes and has a volume of a portion necessary for constant pressure heating expansion turned into a volume of an air motor side, is composed by functionally combining vane rotary air compressors and vane rotary air motors. More particularly, there is an engine conception mainly intended for vehicles of solving, without reducing the engine efficiency, problems concerning complete combustion and prevention of nitric oxide production, which have been generally considered it difficult to realize by reciprocating engines.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 217 words
In a constant pressure heating vane rotary engine, plural air compressors including a primary and a secondary side, and plural air motors of substantially similar construction as said air compressors and including a primary and a secondary side, and each comprised of a rotary vane construction with a common operating shaft for the rotary vanes of said compressors and air motors respectively, said compressors and said air motors being functionally and operatively combined with couplings therebetween, said air compressors being operable to produce an air volume of an extent necessary for constant pressure heating expansion being turned into an adequate volume on the air motor side; said air compressors and said air motors being all respectively operatively coupled by progressively extending connection pipes, each said pipe serving as a gas passage; a combustion chamber operatively mounted respectively in front of the entrance to each said air motor, a water jacket being provided respectively in each of the rotors incorporated by the two units of air motors, a fluid passage being provided along an output shaft to which the two units of rotors are secured, a cylinder cover for the air motors including a water jacket, and the water jacket mounted in the rotor being communicated with the water jacket mounted in the cylinder cover by said passage.
