Abstract

The invention relates to valve device preferably for the control of the flow from an evacuation device, wherein the valve device includes a valve housing, connection openings and a through flow channel, the channel including a wider portion, in which a valve body is axially movable and arranged to in a specific position axially engage an sealing and abutment edge.The novelty lies in that at an end face of one portion of the valve housing enclosing one of the connection openings is arranged at least one annular cylinder in the shape of an axial groove, the annular grove or cylinder being essentially closed at one end at the opposite end opening towards the wider channel portion of the channel, and in said annular cylinder there is an annular piston means, on introduction of pressure fluid at the essentially closed cylinder end arranged to be displaced outwardly in order to engage connection means at the valve body and displace same away from its sealing position against the force of a spring means.
