Abstract

Inventia se refera la un dispozitiv de retinere deblocabil, utilizat la lucrari subterane, în special ca dispozitiv de dislocare si lucru, în cazul unitatilor de tipul pistonului cilindru folosit la stîlpii de sustinere actionati hidraulic, mecanismele cu piston de împingere, cilindrii de retur si altle asemenea, care consta în estenta dintr-un element de comanda etans condus longitudinal, coroborat cu o piesa de închidere o camera de evacuare dispusa în aval de acest corp de închidere. în acest fel, spre deosebire de supapele de dislocare si lucru cunoscute, acestea nu manifesta, în cazul unor inevitabile socuri, de detenta a fluidului de lucru, o tendinta spre vibrare sau fulare. Acest dispozitiv asigura folosirea sa astfel încît elementul de comanda sa se gaseasca în echilibru de presiune si sa fie neutru la desprinderea corpului de închidere.
