Hydraulic motor - has propulsion members located between eccentric cam associated with shaft and counter-element with slidable elements moving in longitudinal direction and having annular bearing shoulders kept pressed against eccentric cam

摘要

The motor with propulsion members (10) has located between an eccentric cam (3) associated with a shaft (2) and a counter-element (1b). The propulsion members (10) consist of two elements (11,12) telescopically liable with respect to one other in the longitudinal direction and having annular bearing edges (11a,12a) kept pressed against corresponding sliding-contact surfaces (3a,1a) of the eccentric cam The resilient members (16) are arranged outside the said propulsion members (10;110) and arranged between said annular edges (11a,12a) and associated member (13,14,17,18) for mechanically retaining them. The resilient means consist of springs (16).
