Patent ID: 7975597

Claim:
A hydraulic machine, in particular a hydraulic motor, comprising: a casing ( 1 ); a piston ( 4 ) capable of sliding with a reciprocating movement in the casing, the piston separating two chambers ( 8 , 9 ) of the casing; hydraulic switching means (C) for supplying liquid to and for evacuating the chambers separated by the piston, these switching means being controlled by the movements of the piston and comprising at least one connecting rod ( 14 ) acting on a distribution member ( 15 ) which can adopt two stable positions; and triggering means comprising a pusher ( 18 ) capable, at the end of the stroke of the piston, of causing a sudden change in the position of the switching means, under the action of an elastic means (E), in order to reverse the stroke, characterized in that the elastic means (E) is secured, at each of its ends, to an articulation member ( 20 a , 20 b ) respectively accommodated in a housing ( 21 , 22 ) provided on the connecting rod and on another moving part ( 18 ) of the machine, each housing ( 21 , 22 ) being open in a direction substantially opposite to the direction of the force exerted by the elastic means (E) in the housing, such that each articulation member ( 20 a , 20 b ) can be removed from its open housing ( 21 , 22 ) against the action of said force, thereby simplifying assembly and disassembly.
