PCT No. PCT/CH83/00101 Sec. 371 Date May 15, 1984 Sec. 102(e) Date May 15, 1984 PCT Filed Sep. 5, 1983 PCT Pub. No. WO84/01199 PCT Pub. Date Mar. 29, 1984.In a drive device operated by pressure fluid a progressive linear or swinging or rotary movement of a driven element is produced by means of at least one lifting element. Between the lifting element and the driven element there is arranged at least one wedge which carries out a stepwise reciprocating movement under the influence of the lifting element. In this way the driven element is pushed forward step by step in the loaded direction via a force locking. This drive device permits a force-locked connection to the object to be moved. |
