Abstract
A cylinder including a control slide supported in a piston in a cylinder. The control slide is supported in a slide guide, the slide guide is supported in a valve housing with a play. The provision of the play has the advantage that deformation of the valve housing has no influence on a gap between the control slide and the slide guide. The proposed cylinder is intended in particular for use as a shock absorber for vehicles.
Claims15
A cylinder (2) having a cylinder tube (10) and having a piston (12) displaceably supported in the cylinder tube (10), and having a valve device (20) with an actuatable control slide (21) guided by a slide guide (23) having a longitudinal length, wherein the slide guide (23) is fixedly supported in a valve housing (24) against axial movement, and a play (60) formed by a radial spacing along at least substantially the longitudinal length of said slide guide is present between the slide guide (23) and the valve housing (24), which upon a deformation of the valve housing (24) any place along said radial spacing keeps this deformation away from the slide guide (23).
