Abstract

Il trovato si inserisce nel campo dei dispositivi idraulici di sicurezza per bloccare l'alimentazione di carico o utilizzatore idraulico nel caso si verifichi il superamento di una sollecitazione massima ammissibile di una struttura posta sotto controllo tramite un sensore idraulico.Il dispositivo prevede una valvola differenziale (18) che riceve il segnale dal sensore idraulico e consente lo spostamento di un pistoncino (7) atto a porre in comunicazione un condotto di alimentazione (13) di una pompa di alimentazione di un distributore con un condotto di scarico (15).Il dispositivo prevede inoltre un blocco temporizzatore (2) che ha la funzione di permettere qualsiasi manovra migliorativa sul distributore per un certo tempo prefissato.The invention is part of the field of hydraulic safety devices to block the load or hydraulic user power supply if a maximum admissible stress of a structure placed under control by means of a hydraulic sensor is exceeded. The device provides a differential valve ( 18) which receives the signal from the hydraulic sensor and allows the movement of a piston (7) capable of communicating a supply conduit (13) of a supply pump of a distributor with an exhaust conduit (15). it also provides a timer block (2) which has the function of allowing any improvement maneuver on the vending machine for a certain preset time.
