Definitions

  • the invention relates to an axial flow Bares fluid valve, in particulardeffenabsperrventil, with an electromagnet having a coil, a core and an armature and magnetic yokes, a housing in which the electromagnet is arranged, an inlet nozzle, which at a first axial end of the Housing is mounted and in which a Umströmungs phenomenon is arranged, which has a valve seat, an outlet nozzle which is fixed to an opposite axial end of the housing and a flow-through tube which is secured to the armature.
  • Such fluid valves are also referred to as coaxial valves, hydraulic valves ordeementabsperrventile. These fluid valves are used, for example, to shutdown or release a coolant path in a motor vehicle, on the one hand to ensure the fastest possible heating of the flow-through aggregates and on the other hand to prevent their overheating.
  • coaxial valves are used, which produce acceptable pressure losses with reduced weight and small installation space and at the same time provide a sufficient flow cross-section. Due to the small sizes and consequently small and light moving parts, the power consumption of these fluid valves is relatively low.
  • Such a coaxial valve is known for example from EP 1 255 066 A2.
  • This valve has a tube serving as a closing body, which is fixed radially inside an armature of the electromagnet and extends through the core to the opposite axial end of the electromagnet.

  • a similar, but normally open coaxial valve is disclosed in DE 197 29 553 AI.
  • the space in which the armature is arranged to be movable is also sealed off here from the fluid to be delivered.
  • a closed valve is understood to mean a valve in which a fluid flow is interrupted by the bearing of a closure member on the valve seat. When the fluid valve is open, a complete pressure equalization over the moving parts is established.
  • the tube abuts axially against the armature and an annular end of the armature facing away from the tube and an annular end of the tube facing away from the armature have a same diameter, wherein the two annular axial ends are usable as bearing surfaces, which with a valve seat interact.
  • This allows a two-sided closure by the tube or by the anchor by forming an opposite valve seat.
  • the inlet connection and the outlet connection can be fastened on both sides of the housing, so that either the annular support surface of the anchor or the annular support surface of the tube cooperates with the valve seat of the flow body. In this way it is possible, with identical components used to design the fluid valve either as a normally open or normally closed fluid valve, which depending on the installation location or function the same components can be used and always the energetically favorable design can be used.

  • the sealing ring for sealing the interior of the sleeve relative to the inlet nozzle is designed as a lip seal, the lip ends facing axially to the support ring and the lip carrier rests against the constriction of the sleeve or against the core. Accordingly, the position of the sealing ring is fixed in the fluid valve and thus the space in the sleeve relative to the inlet side in the closed state of the fluid valve reliably sealed, because such arranged lip seals improve their pressure at elevated pressure Sealing effect by the contact pressure of the sealing lips is increased to the opposite housing by the pressure gradient.

Abstract

On connaît les soupapes à fluide pouvant être parcourues axialement par un fluide, en particulier des soupapes d'arrêt d'agent de refroidissement, qui comportent un électroaimants (10) présentant un noyau (26) et une armature (28) ainsi que des éléments de reflux (18, 20, 22) magnétiques, un carter (12) dans lequel est disposé l'électroaimant (10), une tubulure d'entrée (60) qui est fixée à une première extrémité du carter (12) et dans laquelle est monté un corps à écoulement périphérique (78) qui présente un siège de soupape (58), lesdites soupapes à fluide comportant également une tubulure de sortie (70) qui est fixée à une extrémité axiale opposée du carter (12) et un tube (48) fixé à l'armature (28), qui peut être parcouru par un fluide. L'invention vise d'une part à pouvoir commuter une telle soupape avec une force électromagnétique réduite et d'autre part à pouvoir la concevoir sous forme de soupape à fluide ouverte ou fermée sans courant, sans devoir modifier de parties. A cet effet, selon l'invention, l'armature (28) est guidée dans un manchon (24) dont l'intérieur est rendu étanche vis-à-vis de la tubulure d'entrée (60) au moyen d'une bague d'étanchéité (98) et présente une liaison fluidique avec la tubulure de sortie (70), de sorte qu'un espace (112) situé entre l'armature (28) et le noyau (26) est rempli de fluide, dont la pression correspond à la pression au niveau de la tubulure de sortie.
