摘要

The light-running piston pump is driven by a drive motor (6) arranged in a frame (13) and activating via a drive medium (4) and a reduction gear a flywheel (1) rotatably arranged also in the frame. Through the traverse (9) connecting the frame, on one side extends rotatably the axis of the flywheel, on one side of which a connecting rod arm (7) is fixed. A pivotable connecting rod (2) of the piston (3) connects the light-running piston pump with the connecting rod arm. Through the traverse connecting the frame on the other side the other end of the axis of the flywheel extends rotatably, on the outside of which are fixed counterweights (8) circulating with the flywheel. On the outside of the extending axis of flywheel a connecting rod arm (7) is fixed and a pivotable connecting rod connects a membrane pump or a vane cell pump or other pump with oscillating drive movements to the connecting rod arm.
