Abstract
Il presente trovato concerne un dispositivo per l'avviamento e l'arresto automatici del gruppo motore-pompa, in particolare di idropulitrici.Esso prevede un organo sensore (14), applicato direttamente sul condotto di mandata (2), il quale è in grado di rilevare le sovrappressioni che si manifestano nel condotto di mandata (2) a monte e di agire, in caso di attivazione, su un microinterruttore (15) che è inserito sul circuito elettrico di alimentazione del motore che aziona la pompa, in serie con l'interruttore generale. Allo stabilirsi di una sovrappressione a monte nel condotto di mandata l'organo sensore (14) agisce sul microinterruttore (15), il quale apre il circuito elettrico di alimentazione arrestando il motore.
