Title: Rotary engine with oscillating piston compression-combustion stage - has baffle plates dividing working chamber and cylindrical bladed sleeve with radial blades driven by exhaust gases
Inventor: WELTER JOHANN
IPC: F01C9/00
Filed: 1976-01-03
Abstract: Turbine engine with oscillating-piston compression and combustion stage has a main shaft. In the engine centre is a cylinder divided into two equal size working chambers by rectangular baffle plates which are constrained to move together angularly and can do so between steps in the cylinder surface, covering/uncovering inlet/outlet ports in the process. The chambers also accommodate wing-shaped pistons (5) fixed to a hollow spindle free to rotate on the main shaft and forming the inside chamber boundary. In the spaces between pistons and baffles a combustion cycle proceeds, causing oscillation of the pistons. This is converted to rotation of the main shaft by means of a crank system, driven from a plate mounted on the hollow spindle, in a crankcase adjoining the cylinder. At the end away from the crank, the main shaft supports a cylindrical sleeve which runs in the space between the cylinder and an outer casing. Over an angle of 90 deg. on opposite sides this sleeve has radial-turbine blades driven by the exhaust gases from the cylinder. The sleeve also has ports which, in combination with others in the casing and those in the cylinder, to regulate the inflow of the combustible mixture.
