Abstract: front page image
(EN)Hydraulic machine, in particular hydraulic motor, comprising a casing, a differential piston (4) having a region of large cross section and a region of smaller cross section, which can slide with a reciprocating movement respectively in the casing and in a housing coaxial to, and of smaller diameter than, the casing, the piston separating two chambers of the casing and being provided at the location of its large cross section and its small cross section with sealing lips (48, 49) which are oriented in opposite directions and which face one another. The sealing lips (48, 49) are provided on detachable circular rings (50, 51), and the piston (4) is moulded in one piece.
(FR)Machine hydraulique en particulier moteur hydraulique, comprenant une enveloppe, un piston différentiel (4) présentant une zone à grande section et une zone à plus petite section, propre à coulisser en mouvement alternatif respectivement dans l'enveloppe et dans un logement coaxial à l'enveloppe et de plus petit diamètre, le piston séparant deux chambres de l'enveloppe et étant muni au niveau de sa grande section et de sa petite section de lèvres d'étanchéité (48,49) orientées en sens opposé et tournées l'une vers l'autre. Les lèvres d'étanchéité (48,49) sont prévues sur des bagues circulaires démontables (50,51), et le piston (4) est moulé d'une seule pièce.
