Abstract

A discharge valve for vacuum cleaners, comprising an outer valve element (1) which is connected with at least one discharge channel in the vacuum cleaner, and a movable inner valve element (5) disposed in the outer valve element. The outer valve element (1) comprises a valve opening (3) configured such that a coupling element (2) connected with an external hose may be secured or attached to the discharge valve. When the discharge valve is closed, the outgoing flow of air is conveyed through at least one opening (4) in the outer valve element and further on to at least one discharge hole. When the discharge valve is opened, the inner valve element (5) is moved into the discharge channel, whereby the outgoing flow of air is conveyed into the discharge valve via the opening (4) and at least one opening (7) in the inner valve element and further out through the valve opening (3).
