<p>The invention relates to a device (10) comprising a cylinder body (17) in an inner bore hole (22) in which a piston (21, 42) is mounted in such a way that it can slide axially, whereby the cylinder body (17) comprises at least one part in the front of the blind hole (17a) and one center part bearing a sealing joint, whereby both parts are fitted axially and consecutively from front to back and are interfixed in a sealed manner. Said inner bore hole comprises two front and rear sections which are substantially coaxial and concentric and are used to guide the piston (21,42) in an axially sliding manner. The invention is characterized in that both front (62) and rear (60) sections which are used to guide the piston (21,42) in a sliding manner belong to the center part (17B,64) of the cylinder body.</p> |
