Abstract
A pressure fluid-delivery device comprising a cylinder, a piston and a reservoir for a fluid. A V-seal is mounted in an annulus between the cylinder and the piston. An axial movement of the piston forwards relative to the cylinder results in a delivery of a pressure fluid from the cylinder space. A first leg, in a similar fashion to a check valve, hereby springingly attempts to seal an outlet opening of a channel, which communicates with the reservoir. When the piston is moved backwards, this leg can open the outlet opening, admitting fluid into the cylinder space. The seal rests on a forwardly facing, radially outwardly extending surface of the piston. The seal's first leg projects slantingly radially inwards and is arranged to come into abutment against an axially extending portion of the piston. The seal's second leg projects slantingly radially outwards and constantly abuts sealingly against the cylinder surface.
