Definitions

  • the system pressure is lowered via a pressure reducing valve and the control pressure is thus kept ready for the actual drive of the soil compaction machine.
  • the switching device 24 furthermore has an energy accumulator in the form of a return spring 28, which the switching device 24 in its "exhibition shown in FIG. 1.
  • an actuating part 30 is provided which brings the switching device from the" exhibition shown in FIG. 1 to the operating position in which the fluid-carrying path between N and T.
  • two opposite control spaces 32, 34 of the switching device 24 are connected to one another in a fluid-carrying manner via at least one fluid path 36 and at the same time to the control connection N of the control block 26 via a groove 88.

Abstract

L'invention concerne un dispositif permettant de piloter et d'actionner un mécanisme à vibrations, notamment dans des engins de compactage des sols. Ledit dispositif comprend une pompe hydraulique (12), qui entraîne un moteur hydraulique (18) coopérant avec le mécanisme à vibrations (10), ledit moteur faisant partie d'un circuit hydraulique (16), auquel est raccordé un régulateur de pression (22) dans la branche secondaire (20). La commande du régulateur de pression peut être assurée au moyen d'un dispositif de commutation hydraulique (24). Cette conception caractéristique permet de parvenir à une solution purement hydraulique, qui convient pour lancer et arrêter le mécanisme à vibrations ou pour le courant électrique.
