Abstract

Improved device for fluid dynamic drive suitable for transforming a straight-line motion into a rotary motion, comprising a body with internal cylindrical body (11) in which two pistons (12 and 13) are assembled in a sliding manner, each one being equipped with a protruding part (16 and 17) with a rack (52 and 53) working in conjunction with a pinion (18) to which the straight-line movement of the pistons is transmitted and a pair of side plates (34 and 35) enclosing between them the said body (11), comprising in addition a radial pipeline (30) which puts into communication the chamber (29) between the said pistons (12 and 13) and the outside and a lengthwise pipeline (36) putting into communication each of the chambers (32 and 33) defined between the said plates (34 and 35) and the heads of the said pistons (12 and 13), whereby the said lengthwise pipeline (36) possesses a radial outlet (37) near an annular passage (51) foreseen on each of the said side plates (35 and 36), each of the said side plates being equipped with a first set of expansion/compression chambers (39-44) and with a second set of expansion/compression chambers (45 - 50), the chambers belonging to the said first set being intercommunicating and communicating in pairs, with the single chambers of the said second set, the said second set of chambers communicating in addition with the said annular passage (51).
