Abstract

L'invention concerne un ensemble de commande 14 pour doser l'écoulement d'un fluide frigorigène, entre le côté haute pression et le côté basse pression d'une machine de réfrigération 1. L'ensemble 14 comprend une plaque porte-soupape 20 munie d'un orifice circulaire et un obturateur 25 qui comporte une tête conique et une tige montée coulissante dans un guide 30 fixé à la plaque 20. L'obturateur est sollicité en position fermée par un ressort 35. Dans ses positions fermée et ouverte, l'obturateur délimite avec l'orifice de la plaque 20 des orifices annulaires respectifs dont les surfaces de section transversale respectives sont déterminées par une caractéristique de fonctionnement de la machine pour laisser passer les quantités appropriées de fluide frigorigène aussi bien dans les conditions de fonctionnement normales que dans les conditions de fonctionnement sous de faibles charges. L'invention est applicable, notamment, aux machines de réfrigération utilisées dans les installations de climatisation.
