DISPOSITIVO INTECETTORE DI MICROTRAFILAMENTI, PER EVITARE E/O SEGNALARE PERDITE D'OLIO IN IMPIANTI IDRAULICI E PER IMPIEGHI EQUIVALENTI

摘要

A unidirectional valve (7) forms a reduced meatus which extends in the direction of the obturator (23) movement, which meatus is to be passed through by possible microleaks in case of losses in the actuator branch (3); a considerable run of the obturator (23) in the presence of microleaks and of consequent pressure losses is thus obtained; a sensor (47) detects the obturator displacements.
