Abstract (en)

[origin: EP0685647A2] A variable-displacement hydraulic motor with radial cylinders supplied by a rotary fluid distributor (4) and acting on an eccentric ring (6) axially secured to a crankshaft (7) but capable of moving radially with respect thereto, being provided with a device for operating and controlling the variation of eccentricity of eccentric ring (6) with respect to crankshaft (7), which comprises at least one pair of actuating pistons (8, 9) located in counterposition to and independent of one another, arranged in a radial sense between shaft (7) and ring (6), each of which is made mechanically integral with such eccentric ring (6) via appropriate means of connection (8a, 9a), and at least one pair of cross-connected valves (10) to block the flow of the fluid operating such actuating pistons (8, 9). <IMAGE>
