Abstract[English]
An axial piston device having a high-pressure side and a low-pressure side. The axial piston device includes a pressure transition passage (78) that transitions the pressure in piston chambers (60) of the axial piston device as the piston chambers transition from one of the low and high pressure sides of the axial piston device to the other of the low and high pressure sides of the axial piston device. The pressure transition passage includes first and second restrictions (90, 92) separated by a pressure recovery chamber (94).[French]
Dispositif à piston axial présentant un côté haute pression et un côté basse pression. Le dispositif à piston axial comporte un passage de transition de pression (78) qui fait subir une transition à la pression dans les chambres de piston (60) du dispositif à piston axial à mesure que les chambres de piston passent de l'un des côtés basse et haute pression du dispositif à piston axial à l'autre des côtés basse et haute pression du dispositif à piston axial. Le passage de transition de pression comporte des premier et second organes de restriction (90, 92) séparées par une chambre de récupération de pression (94).
