Abstract (en)

[origin: US2006037465A1] The invention concerns a hydraulic machine, in particular a hydraulic motor, comprising: a body ( 1 ), a piston ( 9 ) adapted to slide in reciprocating motion in a cylindrical housing ( 7 ) of the body, a chamber (C 1 , C 2 ) being formed on either side of the piston, hydraulic switching means for feeding and evacuating the respective chambers (C 1 , C 2 ), control means (H) for abrupt change of the position of the switching means, and triggering means ( 13, 15 ) for, at the end of the stroke of the piston ( 9 ), changing the position of the switching means. The piston ( 9 ) is a single acting and non-differential piston, having a closed cross-section and the switching means are arranged in the body ( 1 ) of the machine, radially outside the cylindrical housing ( 7 ) wherein slides the piston ( 9 ).
