Abstract
Eliminador de resistencia de contrapesos. El o los anillos extremos y el o los contrapesos unidos al rotor de un compresor hermético están situados dentro de una cubierta que los aísla del interior del compresor. La cubierta puede ser fija o puede girar como un todo con el rotor, el anillo extremo y el contrapeso. En cada realización, se impide que el contrapeso asimétrico se comporte como un ventilador con respecto al interior del cuerpo y, por tanto, se impide que genere un gradiente de presión que tienda a actuar sobre el cárter y de lugar a un régimen superior de circulación de aceite al sistema de refrigeración. Figura 1.
