Definitions

  • the invention relates to a motor pump unit according to the preamble of the first claim.
  • the cooling fluid is withdrawn through respective ports either to the outlet of said pump, or circulated by another pump connected via additional conduits forming a flange surface within the parent device
  • the above-mentioned electric motor and the above-mentioned pump advantageously have a common shaft for supporting their rotors. As a result, a clutch is avoided and space is saved.
  • Fluid pressure at the working port compares and in a deviation from the predetermined by the solenoid setpoint of the fluid pressure, the inflow and / or outflow of fluid to the working port or away from the working port changed so that the fluid pressure at the working port changes to the desired value.
  • a motor pump assembly is provided.
  • a rotor (18) of the electric motor (2) and a rotor (19) of the hydrostatic pump (3) are mounted together by means of a shaft (20).
  • valve (5) is a directional control valve connected between two end positions by the electromagnet (4).

Abstract

L'invention concerne un ensemble motopompe. L'invention vise à réaliser ce dernier à moindres coûts et en adéquation avec une production en série de telle sorte qu'une multitude de composants électriques sont raccordés conjointement au moyen d'un système de connexion enfichable, la quantité d'outils requise devant être maintenue à un faible niveau. Le groupe motopompe est pourvu à cet effet d'un enrobage en plastique (6). L'enrobage en plastique (6) forme un couvercle (7) du moteur électrique (2), entoure une bobine magnétique (8) et au moins un élément de guidage de flux (21) de l'électroaimant (4), forme un boîtier connecteur (9) pour un système de connexion enfichable (23) électrique et entoure les pistes conductrices (10) menant au système de connexion enfichable (23). L'ensemble motopompe selon l'invention est utilisé pour l'activation d'actionneurs hydrauliques mécaniques à action proportionnelle à l'aide d'une commande avec précision de la force et de la vitesse de la pièce mécanique de l'actionneur en fonction des signaux d'entrée électriques pour le groupe motopompe.
