Abstract

Cada compresor que forma parte de un circuito tiene una bomba de aceite con una capacidad suplementaria en relación a los requisitos de lubricación delcompresor respectivo. La capacidad suplementaria se desvía a una línea común que se conecta a cada uno de los compresores que forman parte del circuito, através de una válvula de flotador. Cada válvula de flotador se activa en respuesta al nivel de aceite del compresor correspondiente, de modo tal que elaceite desviado como capacidad excedente se deriva a cualquier compresor del circuito que esté sin aceite.
