HYDRAULIC MOTOR WITH RADIAL PISTONS AND CONTROL BY CYLINDER

摘要

Hydraulic motor (10) with radial pistons, with a cylinder block (12), two principal channels (26,28), a fluid distributor (30), a distribution valve (32) per cylinder and a control system (34) for the distribution valves (32). The motor has at least two unitary motors and can function in different regimes in which in each unitary motor each of the cylinders each cylinder is connected on ascending ramps to a first main channel, a first unitary motor being a motor in a first regime and inactive or antagonist in a second regime, the control system managing the rest of the hydraulic motors in the same way in the two regimes. Hydraulic circuit comprising said motor. Control method for such a motor.
