Abstract
Abstract A variable explosion-displacement rotary engine, free of a fuel compression cycle, and specifically designed for use with pollution free fuels of the alkyne type; and others, having a cylindrical rotor revolving in an elliptical opening of a housing to define two annular spaces on two sides therebetween. The rotor having radial members which project to follow without sealing the contour of the elliptical opening to form volume expanding combustion areas behind said members. High speed tungsten poppet valves mounted in the fuel input ports which extend into the combustion areas open and close via differential in pressures to admit fuel periodically between explosions, the engine providing four explosions in one shaft revolution. Ignition timing cooperating with the position of said members and the volume of fuel displaced controls the explosive force, the explosion displacement, engine torque and shaft revolutions per minute. The volume of fuel exploded is in direct proportion to the amount of horsepower required at any moment with the fuel-air mixture precisely fixed for complete combustion and pollution free exhaust.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
244 words
A rotary engine comprising: a housing having an open space therein defined by an at least partially elliptical wall; a rotatable cylindrical rotor axially disposed within said space defining at least one substantially crescent shaped chamber; a radially movable blade means carried by said turbine rotor extending into contact with said wall for creating a low pressure in said crescent shaped chamber behind said blade means as said rotor is rotated in one direction; a source of combustible fixed fuel mixture; fuel intake means communicating with said source and with said crescent shaped chamber for introducing fuel inTo said crescent shaped chamber behind said blade means; exhaust means communicating with said crescent shaped chamber at a point spaced angularly from said intake means in the direction of rotation of said rotor; fuel ignition means positioned in communication with said crescent shaped chamber adjacent said intake means for burning the fuel therein creating a high pressure in said crescent shaped chamber; a valve carried by said fuel intake means for opening said fuel intake means responsive to a reduction in pressure in said crescent shaped chamber behind said blade means and closing said fuel intake means responsive to said high pressure in said crescent shaped chamber behind said blade means; and adjustable means for actuating said ignition means at selected positions of said blade in said crescent shaped chamber; whereby controlled volumes of a fixed fuel mixture may be ignited to meet varying power requirements.
