Rotary piston engine with sliding vanes operating with expanding gases

Abstract

Abstract In this machine, vanes (5, 6, 7) are supported in such a manner in a rotatable drum (4) that they simultaneously rotate about the axis of rotation and oscillate about this axis in the longitudinal direction, separating various gas chambers of variable size in a housing from one another. The housing consists of the planar base and cover plates (1, 2) and a swung wall (3) connecting these plates and standing perpendicularly between them, which wall (3) touches the central drum (4) tangentially or in short conformity at three points (12) and is at a maximum distance from the drum at three points (13) opposite the three contact points. The diameter of the housing, measured through the axis of rotation, is always equal to the length of the vanes (5, 6, 7). The drum (4) and thus the drive shaft connected to it are set in rotation by pressure of the gas on the part of the vanes (5, 6, 7) standing proud of the drum (4). Bore holes and indentations (14, 15) in the drum (4) and openings (9, 10, 11) in the plates (1, 2), which release the gas paths alternately at the right time, are used for controlling the inlet and outlet flow of the gas. <IMAGE>
