<p>In the throughflow recess (80) a valve seat is arranged as is a valve body which works in conjunction with the valve seat. The valve body is subjected to the effect of spring devices and is pressed against the valve seat in the closed position by the through-flowing fluid. The spring devices act against the fluid pressure, in order to lift the valve body from the seat. The valve body radially supports on the wall of the throughflow aperture. The valve body or the throughflow recess has a throughflow channel extending between the valve seat and the side of the valve body turned away from the valve seat.</p> |
