Abstract (en)
[origin: EP0764785A2] The valve has two coaxial partly cylindrical longitudinal slides. The average diameter (DS) of the conical jacket-shaped sealing surface of the valve cone (141) of the first slide (140) is larger than the maximum diameter (DF) of the fine control area (141a) behind it. The positive overlap of this area is larger than the jolt-like opening stroke of the first slide, when the valve cone lifts off its seat (132). The surface pressure in the sealing section formed by the contact area between valve cone and the corresponding valve seat (146) is below 150 N/mm<2>.
