FIELD: machine building.
SUBSTANCE: volumetric expansion machine with a pendulum lever is made in the form of a fixed cylindrical housing an internal cylindrical piston that is coaxially located in it, a power rotation axis with a crankshaft, a supporting slide with a power supporting axis located on it and a pendulum power lever. Cylindrical housing is divided into sectors with internal partition walls. Cylindrical piston has external partition walls forming combustion chambers. Supporting slide has one freedom degree. Pendulum power lever attaches the power supporting axis on the supporting slide, the crankshaft and the internal cylindrical piston to each other by means of through turning sleeves. Pendulum power lever with a support point on the supporting slide has the possibility of changing its geometry along the axis at the interval between rotation axes of through turning sleeves. Movable supporting slide and power turning axis of the crankshaft can be located outside the fixed cylindrical housing.
EFFECT: increasing compactness, economy, ecological compatibility and power of an engine with a variable compression degree.
