The invention relates to a device for reducing pressure pulsations caused in a hydraulic system, especially by a pump. Said device comprises a compensation volume (41) with a displaceable wall or membrane (39) that is located in said volume and that shuts off the volume. On one side, said wall or membrane is impinged upon with pulsations and on the opposite side with a counter-pressure which corresponds to at least approximately the average pressure of the hydraulic system. The pressure compensation volume (43) that is applied on the opposite side of the wall or membrane (39) is linked with the hydraulic system via a compensation manifold (51), said manifold (51) opening into the hydraulic system downstream of the compensation volume (41) in the direction of propagation of the pulsations.
L'invention concerne un dispositif pour réduire des pulsations de pression provoquées notamment par une pompe dans un système hydraulique. Ce dispositif comprend un volume de compensation (41) qui présente une paroi ou une membrane (39) mobile, placée dans ledit volume et obturant ce dernier. Cette paroi ou membrane est soumise aux pulsations d'un côté, et à une contre-pression, du côté opposé, correspondant au moins approximativement à la pression moyenne régnant dans le système hydraulique. Le volume de compensation de pression (43) placé sur le côté opposé de la paroi ou de la membrane (39) est raccordé au système hydraulique par l'intermédiaire d'une conduite de compensation (51) qui débouche dans le système hydraulique, en aval du volume de compensation (41), dans le sens de propagation des pulsations.
