摘要

The valve has an extended valve body connected to a pressure chamber. Housing (1) is coaxially arranged with a hood (2). A unit comprises a seat (4) and a cone (5) that are releasably blocked off by a flow channel. Multiple side apertures are formed in surrounding atmosphere by a terminal section (31). The side apertures are formed in the seat and a surrounding wall of the housing and formed in hood-side front end of wall open slots (101). The slots are formed parallel to longitudinal extension of the valve body and evenly distributed over a cylindrical wall.
