ABSTRACT:
A valve slide has a housing with a sealing surface which has portions located one behind the other seen in direction of the axis of a slide passage opening. The portions located one behind the other are connected to outwardly extending plane sealing surface portions through continuously extending curved portions. The imaginary generatrices of the sealing surface portions forming a sealing surface extend parallel to the axis of the slide passage openings. The sealing surface is finished. The closing member has a contact surface corresponding to the shape of the sealing member. The slide can be used in vacuum systems. The closing member is formed of one piece and can be subjected to high accelerating forces, so that the slide can be used for quick-closing valves and emergency valves.
