<p>The hydraulic switching system has a nonreturn valve for a hydraulic control circuit forming a hole pattern in the mounting block. It is used as a multiway valve with two connections to containers. It has one inlet connection and two working connections for generating pressure or for protecting the control apparatus against pressure in a manifold. It ensures sufficient flow cross-section areas in a compact arrangement, which can be converted into another one without a nonreturn valve. The nonreturn valve (21) is fitted into a block with mounting faces (9, 10) at opposite ends. The block has container connections and channels for the tank openings (12, 13) for accommodating the nonreturn valve (21) which opens in the direction of the container.</p> |
