<p>The invention relates to a two-way valve, especially for liquid dispensers. The inventive valve comprises connections (1,2,3) for a liquid reservoir (1a), for a pump and for a liquid consumer. A membrane disk (4) is clamped between a valve housing (5) and a cover housing (6) and lies flat against a surface of a ring seat (10) in whose range (7) an axial opening (8) is located. Said membrane disk (4), at the cover end, lies flat against the surface of a counter ring seat (6a) that has the same diameter. The aim of the invention is to provide, based on a two-way valve, a system with a spring-loaded piston that deviates from the steel ball compression spring system. To this end, an additional two-side gripping (9) of the membrane disk (4) is used that consists of the surface of the counter ring seat (6a) and the surface of a ring seat (2a). In addition to this supplementary clamping (9) a first ring channel (11) is configured which opens into the third connection.</p> |
