Abstract (en)
[origin: EP0508838A1] The motor comprises a body (1) in which a rack (2) is slidably mounted; pressurised fluid means (P) for driving this rack in reciprocating translation; a pinion (3), mounted rotationally in the body and capable of interacting with the rack; an output shaft (4) of the motor rotationally driven by the pinion (3), and an inversion device (C) comprising a distributor (D) for altering the direction of action of the drive means (P) at each end of stroke of the rack. The pressurised fluid drive means (P) comprise two pistons (6a, 6b), respectively connected to each end (5a, 5b) of the rack (2) and capable each of moving in an associated cylinder (11a, 11b) situated on either side of the body (1), the pinion (3) being placed between the two pistons, the pressurised fluid being admitted alternately into one of the chambers (32a, 32b) of the cylinders opposite the rack. <IMAGE>
