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).The application concerns a controlled check valve, used especially in the hydraulic systems of powered roof supports. The valve piston (3.3) is mounted in the cylindrical guide (3.2) of the valve insert (3) with a tolerance of fit of the outer diameter d<sub>2</sub> in the inner diameter d<sub>1</sub> of the cylindrical guide (3.2), constituting the radial runout deviation for a rotary connection. Preferably, the external diameter d<sub>2</sub> of the valve piston (3.3) is 0.65 ÷ 0.53 to the external diameter d<sub>4</sub> of the external control piston (4.3). The valve insert (3) has a gland (3.10) connected to a cylindrical guide (3.2).
