초록 ▼

A longitudinally controllable adjustment device, in particular a gas spring partially filled with a fluid, has a piston disposed on a piston rod and a valve, inside of which a valve body is slidable in its longitudinal direction. It has a tapered section by which a seal, abutting on a sealing face, can be bridged. In order to make possible a long-stroke embodiment and a short-stroke embodiment, the seal has two sealing beads, of which the one sealing bead sealingly abuts in all embodiments against a truncated cone-like sealing face of the valve body, while the other sealing bead, if required, abuts on an optionally provided additional cylindrical sealing face between the truncated cone-like sealing face and the tapered section.

대표청구항 ▼

A longitudinally controllable adjustment device, comprising: a cylindrical housing closed at one end and filled with a pressure medium; a piston rod sealingly extending from the other end of the housing and slidable therein; a piston disposed in the housing and sealingly guided against an inner wall thereof, the piston being fixedly connected with the piston rod and slidable together with the piston rod and which divides the inner chamber of the housing into two partial chambers; a valve for connecting or separating the two partial chambers comprising a slidable valve body actuable by means of a slidably guided trigger pin between a closed position wherein a sealing face of said valve body abuts against a seal and an open position wherein a tapering section of said valve body bridges the seal so as to leave a fluid flow path between said seal and said tapering section; and wherein said seal comprises first and second rounded sealing beads projecting radially inwardly, said first and second rounded sealing beads being axially unsupported, said first rounded sealing bead abutting a truncated cone-like shaped portion of said sealing face of the valve body and said second rounded sealing bead abutting on a cylindrical sealing surface of the valve body adjoining said sealing face having a truncated cone-like shape.
