Abstract (en)
[origin: WO2005059353A1] The invention relates to a valve (1) for controlling highly pressurized liquids. Said valve (1) comprises a valve seat zone (5) where a high-pressure zone (6, 23) and a low-pressure zone (7) can be connected to or disconnected from each other. A seat surface (29) for a conical valve member (3) is embodied on a valve body (2), said seat surface (29) extending in a slanted manner within the valve body (2). The conical valve member (3) is provided with a polyconical geometry (19) in the valve seat zone (5). Said polyconical geometry encompasses at least one first conical surface (20) and a second conical surface (21) which are provided with different cone angles (18, 18a, 27, 28).
