Abstract

Wynalazek dotyczy zaworu hydraulicznego, zwłaszcza zaworu zwrotnego i podpory hydraulicznej, zwłaszcza stojaka obudowy górniczej, znajdujących zastosowanie w szczególności w górniczych obudowach zmechanizowanych. Korpus (3) zaworu zwrotnego (1) w stanie jego zamocowania do podpory hydraulicznej (2) ma przyłącza (5, 6, 7, 8, 9) przebiegające w górę, równolegle do osi wzdłużnej (16) podpory hydraulicznej (2), przy czym korpus (3) ten zamocowany jest do podpory hydraulicznej (2) za pomocą elementu mocującego kształtowego i ewentualnie zabezpieczony w tej pozycji za pomocą śrub przechodzących przez odpowiednie otwory (29) w korpusie (3) zaworu (1). Przyłącza (5, 6, 7, 8, 9) zlokalizowane są korzystnie na co najmniej dwóch stopniach. Do korpusu zaworu zwrotnego mocowane są korzystnie, w sposób rozłączny, przystawki sterujące dodatkowych funkcjami sekcji obudowy. Podpora hydrauliczna ma zamocowany na stałe element mocujący, korzystnie o postaci płytki, na którą kształtowo zachodzi korpus (3) zaworu (1), wyposażonej w dodatkowe, ustalające otwory nagwintowane, a także wlot hydrauliczny do komory podtłokowej.
