<p>An hydraulic flow acts dynamically to effect a rotational movement of the crankshaft. This movement is transmitted to the toggle pivots of a system of toggle levers pivoted in pairs. The levers form closed quadrilaterals and the movement is transformed into a reciprocating movement. The hydraulic motor is disposed directly on the system of toggle levers and, by the intermediary of a link, transforms the movement of the crankshaft into a reciprocating movement of the toggle system in one direction.</p> |
