Abstract

Inventia de fata se refera la un aparat de comanda pentru un circuit hidraulic de lucru, care serveste ca ventil de reglare de dirijare, pentru comanda unui vinci dintr-un tractor. Aparatul de comanda are un sertar de comanda preliminara actionat mecanic, în care un sertar principal de comanda montat axial si solicitat de catre un arc delimiteaza o camera de comanda, ale carei legaturi spre retur pot fi comandate de o prima muchie de comanda, iar spre aductie de o a doua muchie de comanda. în paralel prin intermediul celei de a doua muchii de comanda, un orificiu de strangulare prevazut în sertarul de comanda preliminara duce duce de la aductie în camera de comanda la comutarea acestuia dintr-o pozitie de descarcare într-o pozitie de blocare.The present invention relates to a control device for a hydraulic working circuit that serves as a control regulating valve for commanding a winch from a tractor. The control device has a mechanically driven preliminary control drawer in which a main control drawer axially mounted and requested by an arc separates a command chamber whose return links can be commanded by a first command edge, adduction of a second edge of the command. in parallel by means of the second control edge, a bottleneck provided in the preliminary control drawer leads from the adduction to the control room when switching from a discharge position to a locking position.
