Abstract
Zgłoszenie dotyczy zaworu zwrotnego sterowanego, stosowanego zwłaszcza w układach hydraulicznych obudów zmechanizowanych. Tłoczek zaworowy (3.3) osadzony jest w cylindrycznej prowadnicy (3.2) wkładu zaworowego (3) z tolerancją pasowania średnicy zewnętrznej d<sub>2</sub> w średnicy wewnętrznej d<sub>1</sub> cylindrycznej prowadnicy (3.2), stanowiącą odchyłkę bicia promieniowego dla połączenia obrotowego. Korzystnie średnica zewnętrzna d<sub>2</sub> tłoczka zaworowego (3.3) ma się do średnicy zewnętrznej d<sub>4</sub> zewnętrznego tłoczka sterującego (4.3) jak 0,65 ÷ 0,53. Wkład zaworowy (3) ma dławik (3.10) połączony z cylindryczną prowadnicą (3.2).
