摘要

The device has a valve pin (21) with a pin element and a ball element (23) that is at least partly spherical. The pin element has an aperture facing the outflow opening in which the ball element is inserted and a spring element (22) acts on the pin element towards an initial position in which a connection between the valve chamber and the low pressure region is closed.
