Abstract
A valve arrangement has an outflow seat section defined by at least a tubular side wall. The outflow seat section has a free end with an engaging part extending along the entire periphery of the side wall. The engaging part is adapted for close engagement with an engaging surface of a movable obturating plate. The engaging surface is substantially parallel to a plane of the engaging part and remains substantially parallel to this plane during movement of the obturating plate toward and from the free end of the outflow seat section. During operation of the valve arrangement the engaging surface of the obturating plate simultaneously engages the entire plane of the engaging part of the outflow seat section causing closing of the valve arrangement.
