Abstract

Il dispositivo è caratterizzato da molle in lega con memoria di forma. Le molle sviluppano soltanto in presenza di elevate temperature notevoli forze di regolazione mediante le quali viene aperta, direttamente o indirettamente, una via di intercomunicazione, strozzata solo relativamente poco, tra il lato di mandata e il lato di aspirazione di una pompa.The device features alloy springs with shape memory. The springs develop only in the presence of high temperatures significant adjustment forces through which an intercommunication path, throttled only relatively little, between the delivery side and the suction side of a pump is opened directly or indirectly.
