| 20100282072 | HYDRAULIC MACHINE, IN PARTICULAR HYDRAULIC MOTOR, WITH A RECIPROCATING MOVEMENT - Hydraulic machine includes: a casing; a piston slidable therein and separating two chambers; hydraulic switching elements for supplying liquid to and for evacuating the chambers, including at least one connecting rod acting on a distribution member which can adopt two stable positions; and initiating elements having a pusher which, at the end of the piston stroke, can cause a sudden change in the position of the switching elements, under the action of an elastic member to reverse the stroke. Each end of the elastic member is secured to an articulation member respectively accommodated in a housing provided on the connecting rod and on another moving part, each housing being open in a direction substantially opposed to the direction of the force exerted by the elastic member, such that each articulation member can be removed from its open housing against the action of the force, thereby simplifying assembly and disassembly. | 11-11-2010 |
| 20100269685 | HYDRAULIC MACHINE, IN PARTICULAR HYDRAULIC MOTOR, WITH A RECIPROCATING MOVEMENT, AND DIFFERENTIAL PISTON FOR SUCH A MACHINE - Hydraulic machine, in particular hydraulic motor, comprising a casing, a differential piston ( | 10-28-2010 |
| 20100154625 | HYDRAULIC MACHINE, IN PARTICULAR HYDRAULIC MOTOR, AND METERING DEVICE COMPRISING SUCH A MOTOR - A hydraulic machine includes a casing with a body and a cover; a separation member which can make a reciprocating movement and defines two chambers; hydraulic switching elements including a distribution member; a compartment in the body of the casing connected to a pressurized-liquid inlet, and initiating elements including a pusher connected to the separation member, these initiating elements being able, at the end of the stroke, to cause a sudden change in the position of the switching elements, under the action of an elastic member to reverse the stroke. The distribution member has a distribution slide valve applied against a flat plate which is fixed relative to the body of the casing, the slide valve being able to slide in a fluid-type manner, without a seal, against the plate, which has orifices connected respectively to the chambers and to a liquid outlet orifice. | 06-24-2010 |
