HYDRAULIC ENGINE WITH RADIAL PISTONS ACTING AS A HYDRAULIC STARTER

摘要

The invention relates to a hydraulic engine that comprises a cam (4) connected to a casing (1A, 1B, 1C, 1D), a cylinder block (10) and an internal fluid dispenser (22) provided in the casing, as well as an output shaft (34). The cylinder block and the output shaft can rotate relative to the casing about a rotation axis (A). The engine further includes an inner shaft (30) coaxial with the output shaft (34) and connected to the cylinder block (10) so as to rotate therewith about the rotation axis (A), and a freewheel device (36) provided between the inner shaft (30) and the output shaft (34) in such a manner that the latter can be driven relative to the inner shaft or rotate relative thereto, the inner shaft and the freewheel device being arranged in the casing (1A, 1B, 1C, 1D).
