Hydraulic machine, in particular hydraulic motor, comprising a casing (2) with a body (3) and a cover (4); a separation means (M) which can make a reciprocating movement and defines two chambers (5, 6); hydraulic switching means (C) comprising a distribution member (D); a compartment (13) in the body of the casing connected to a pressurized-liquid inlet (14), and initiating means (15) comprising a pusher (A) connected to the separation means, these initiating means being able, at the end of the stroke, to cause a sudden change in the position of the switching means, under the action of an elastic means (E), in order to reverse the stroke. The distribution member (D) comprises a distribution slide valve (16) applied against a flat plate (17) 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 (17), which has orifices connected respectively to the chambers (5, 6) of the casing and to a liquid outlet orifice (18), the slide valve (16) being intended, depending on its position, to close some of the orifices or to place them in communication with the fluid inlet or the outlet.
Machine hydraulique, en particulier moteur hydraulique, comprenant une enveloppe (2) avec un corps (3) et un couvercle (4); un moyen de séparation (M) propre à effectuer un mouvement alternatif et définissant deux chambres (5,6); des moyens de commutation hydraulique (C) comportant un organde de distribution (D); un compartiment (13) dans le corps de l'enveloppe relié à une arrivée (14) de liquide sous pression et des moyens de déclenchement (15) comprenant un poussoir (A) lié au moyen de séparation, propres à provoquer, en fin de course, un changement brusque de la position des moyens de commutation, sous l'action d'un moyen élastique (E), pour l'inversion de la course. L'organe de distribution (D) comprend un tiroir de distribution (16) appliqué contre une plaque plane (17) fixe relativement au corps de l'enveloppe, le tiroir pouvant coulisser de manière étanche, sans joint, contre la plaque (17) qui comporte des orifices reliés respectivement aux chambres (5,6) de l'enveloppe et à un orifice (18) de sortie du liquide, le tiroir (16) étant prévu pour, selon sa position, fermer certains des orifices ou les mettre en communication avec l'arrivée de fluide ou l'échappement.
