Abstract

The valve unit (23) has a base body (11) made of steel, and the base body holds a continuous pressure-relief valve (15) in an opening (14). The continuous pressure-relief valve has an actuating element (20) loaded by a spring element (19), which actuates a valve ball (21) of the continuous pressure-relief valve against a valve seat (24) of the continuous pressure-relief valve. The valve seat of the continuous pressure-relief valve is formed by a separate insert (25) made of steel.
