摘要

The valve unit (17) has a manual actuating device mechanically connected with a valve component. The actuating device is provided with a curved disk (64), which is pivoted around a pivoting axis. The curved disk is provided with a curved surface along which the valve lifters are moved. The valve lifters are guided translational and parallel to the pivoting axis of the disk and convert the valve component into the raising, lowering or stopping position. A check vale is connected to the valve lifters.
