  • This might be advantageous, since the cooling capacity for the battery only very rarely has to be varied because of its large thermal mass. This means that there is less need to jump between two saw teeth, which reduces the influence of the teeth
  • the fluid flow is a flow of refrigerant, in particular in a vehicle.
  • the valve is preferably used for controlling and controlling a refrigerant. Control is also understood to mean regulation.

Abstract

L'invention concerne une soupape (1, 1a), en particulier une soupape de détente, pour la commande d'un flux de fluide, comprenant un boîtier (10, 10a) pour un élément formant soupape, qui présente une première et une seconde ouverture (12, 12a, 14, 14a), et un élément formant soupape (20, 20a) qui présente une forme globale à symétrie de révolution, et qui est monté mobile en rotation à l'intérieur du boîtier (10, 10a). Selon l'invention, l'élément formant soupape (20, 20a) présente un évidement (30, 30a, 30b, 30c) de dimension variable et une partie (32, 32a) de l'évidement (30, 30a, 30b, 30c) est conformée pour traverser l'élément formant soupape (20, 20a).
