Abstract

L'invention concerne un compresseur pour systèmes de climatisation, notamment pour des véhicules automobiles, ou un système de climatisation équipé d'un tel compresseur. Selon l'invention, le compresseur est raccordé à une zone haute pression et à une zone de pression d'aspiration. Eventuellement, un retour de la pression de chambre de commande s'effectue de la zone de pression de chambre de commande vers la zone de pression d'aspiration, à partir de la chambre de commande du compresseur et éventuellement un filtre, notamment un filtre à particules d'impuretés, est placé dans la zone de pression d'aspiration.
