PNEUMATIC BELLOWS-TYPE ENGINE

摘要

The invention relates to mechanical engineering. The inventive pneumatic bellows-type engine (pneumoengine) uses rotatable membrane-diaphragm bellows. Said engine can operate with a highly and ultrahighly pressurised working gas. Said engine is embodied in the form of two or more principally analogous operational units (1, 2) in which said bellows are mounted. The units are combined by the rotating shafts thereof. The bellows in the units operate in opposite phases, wherein one unit is provided with a direct-action freewheel clutch (8) which transmits a corresponding rotational movement of the movable elements of the combined units to an output power take-off shaf (10). The other unit is provided with a reversible freewheel clutch (12) for converting the backward motion of the movable elements of the units (1,2) into an opposite motion, i.e. converts it into a rotation unidirectional with the output rotation of the first freewheel clutch (8) and transmits the thus obtainable resulting unidirectional rotation to the common output shaft (10) of the pneumoengine with the aid of a mounted longitudinal central shaft (17) which connects said freewheel clutches to each other. Said invention makes it possible to increase the reliability and performance of the pneumatic engine and to extend the application scope thereof by the ability of said engine to operate with highly and ultrahighly pressurised gases.
