Abstract

Una disposición de refrigeración o de bomba de calor que comprende un evaporador, un compresor, un condensador y unos medios de obturación de gases, comprendiendo el compresor un motor eléctrico y una bomba de movimiento alternativo, bomba que comprende un cilindro, en el que se desplaza un pistón con movimiento alternativo por la acción del motor eléctrico a fin de trabajar en un espacio de compresión por encima del pistón, compresor que tiene una abertura de entrada y otra de salida, las cuales están conectadas, respectivamente, al evaporador y al condensador por medio de tubos de conducción, y comprendiendo además una parte de aspiración y un conducto de derivación por medio del cual la parte de aspiración puede ponerse en comunicación con el espacio de compresión al controlar un miembro de válvula en la derivación, caracterizada porque el miembro de válvula está controlado electromagnéticamente y el sistema comprende un mecanismo de control que reduce la potencia del motor eléctrico deun modo racional cuando está abierta la derivación.
