<p>In a mechanism driven by a pressure device, the generation of a rectilinear or articulated or rotary progressive motion of a driven element is obtained by means of at least one lifting member. At least one wedge is arranged between the lifting member (13, 14) and the driven element. This wedge is subjected to the influence of the lifting member (13, 14) which imparts thereto a reciprocating step motion. Thus, the driven element is pushed forward step by step in the load direction beyond the friction force. This motor mechanism allows an adherent connection with the object to be moved.</p> |
