摘要

The valve system comprises valves (2) whose housing is longitudinally divided into several housing components (7). Recesses (17) across the housing define the cavities (18) of the housing components. Some of these form valve channels (22) while others are fitted with valve pistons (25) and electrical controls (37) for these.
