Abstract

Amortyzator hydrauliczny o zmiennej sile tłumienia zawierający tłoczysko i tłok z górnym zespołem zaworowym, umieszczone w rurze wewnętrznej, która jest umieszczona szczelnie w zawalcowanej u góry rurze zewnętrznej, a także zawierający usytuowany pomiędzy komorą roboczą oraz przestrzenią rezerwową dolny zespół zaworowy posiadający co najmniej jeden zwrotny kanał charakteryzuje się tym, że dolny zespół zaworowy posiada dysk obrotowy (9), usytuowany w osiowo-symetrycznym gnieździe wykonanym w zamknięciu (10) rury wewnętrznej (1) i wyposażony jest dodatkowo w co najmniej jeden regulacyjny kanał (C) łączący komorę roboczą z przestrzenią rezerwową, który jest wykonany przelotowo w zamknięciu (10) oraz w dysku obrotowym (9). Dysk obrotowy (9) osadzony jest na wale sterującym (11) ułożyskowanym i uszczelnionym w zamknięciu (12) rury zewnętrznej (2), a ponadto wylot zwrotnego kanału (R) od strony komory roboczej jest zabezpieczony płytką zaworową górną (7), a od strony komory rezerwowej wylot regulacyjnego kanału (C) jest zabezpieczony płytką zaworową dolną (8).A hydraulic damper with variable damping force, containing a piston rod and piston with an upper valve assembly, placed in the inner tube, which is sealed tightly in the upper rolled outer tube, and also containing a lower valve assembly between the working chamber and the reserve space having at least one return duct characterized by the fact that the bottom valve assembly has a rotary disk (9), located in an axially symmetrical seat made in the closure (10) of the inner pipe (1) and is additionally equipped with at least one control channel (C) connecting the working chamber with the space backup, which is made through in the closure (10) and in the rotary disk (9). The rotary disk (9) is mounted on the control shaft (11), mounted and sealed in the closure (12) of the outer pipe (2), and the outlet of the return channel (R) from the working chamber side is protected by the upper valve plate (7), and from on the reserve chamber side, the outlet of the control channel (C) is protected by a bottom valve plate (8).
