Abstract

Cylinder prowadzący (9) ma na przeciwległym do dna (10) końcu założoną tuleję zamykającą (12) z kołnierzem wewnętrznym. Do osadzonego wewnątrz cylindra prowadzącego (9) elementu sprężystego (11) przylega element cierny (13), mający kształt walca wyposażonego w kołnierz, natomiast średnica kołnierza jest niemal równa ze średnicą wewnętrzną cylindra prowadzącego (9). Kołnierz znajduje się wewnątrz cylindra prowadzącego (9), a pozostała część elementu ciernego (13) wystaje na zewnątrz przez światło tulei zamykającej (12), ponadto w stanie najbardziej rozprężonego elementu sprężystego (11) kołnierz elementu ciernego (13) opiera się o kołnierz tulei zamykającej (12).
