Definitions

  • the aim of the invention was to eliminate the deficiencies mentioned and to develop a uniform gate direction with which the most varied hydraulic work equipment can be operated in an operating mode determined by the work to be carried out, and which can be easily adapted to the new work equipment after the work equipment has been replaced can.
  • the object of the invention was assigned to ensure the hydraulic operation with a suitable control.
  • the air conditioner (cooling, decompression, oil lubrication) ensures the air supply to the pressure converter with the aim of being able to achieve a longer service life.
  • the quantity valves 4, 5 determine the speed, while the quantity valves 6, 7 determine the time instead of it a time valve of any type can be used.
  • the control option ensured by the four quantity valves 4, 5, 6, 7 mentioned enables a wide variety of operating modes.
  • Pigur 2 represents some examples of these variations, in which so-called path-time diagrams are illustrated.

Abstract

Transducteur de pression à commande pneumatique servant à actionner des organes hydrauliques de travail et pourvu d'un cylindre moteur double; sur un de ses côtés il y a un cylindre actionné pneumatiquement, sur l'autre de ses côtés un cylindre à action hydraulique; il est aussi pourvu de moyens de travail hydrauliques raccordés au côté hydraulique. L'essentiel de l'invention consiste en la présence d'une soupape de commande reliée à la chambre primaire qui se trouve devant le piston du cylindre pneumatique du cylindre moteur, soupape qui est en liaison de manoeuvre avec une soupape de démarrage tout en étant reliée par une soupape d'étranglement de retenue avec une autre soupape, et d'autre part en étant reliée par l'entremise d'un clapet de drainage avec le réservoir hydraulique, respectivement par la soupape avec la chambre secondaire du cylindre pneumatique. Une autre caractéristique essentielle consiste en ce que la soupape de commande est reliée par la soupape d'étranglement de retenue du réservoir hydraulique avec le cylindre hydraulique du cylindre moteur double, pour permettre ainsi une obturation à l'aide du piston hydraulique. La conduite située entre la soupape et le cylindre se trouve en liaison de commande avec la soupape de commande par l'entremise d'une soupape d'étranglement de retenue supplémentaire. Le transducteur de pression selon l'invention représente un dispositif relativement bon marché à structure unitaire et simple, à l'aide duquel les organes hydrauliques de travail les plus divers peuvent être actionnés d'une façon qui est déterminée par les organes de travail appliqués ainsi que par le mode d'opération assujetti à la tâche à accomplir.
