Abstract

Il trovato in oggetto è riferito ad un dispositivo fra rotore e girante di elettropompe o simili con motore a magneti permanenti.Il dispositivo comprende mezzi di vincolo elastico rotazionale costituiti preferibilmente da una molla ad elica cilindrica che associano il rotore alla girante.The present invention relates to a device between rotor and impeller of electric pumps or the like with a permanent magnet motor. The device comprises rotational elastic constraint means consisting preferably of a cylindrical helical spring which associates the rotor with the impeller.
