Embodiment Construction

[0026] The valve assemblies, which are not shown to scale in the figures, each comprise a valve block 2 and an integrated valve 1 arranged in said valve block 2 .

[0027] The valve block 2 has graded holes: a main hole 21 and a receiving hole 10 . A radial bore associated with the B-port 20 opens into the main bore 21 . A guide hole 24 leading to the A-interface 19 is attached to the receiving hole 10 . The diameter of the guide hole 24 is smaller than the diameter of the receiving hole 10 .

[0028] The built-in valve 1 each comprises a sleeve 3 and a closing element 4 which is movably mounted in the sleeve 3 .

[0029] The sleeve 3 has an upper end region 5 which is fixedly and thus immovably connected to the valve block 2 at least indirectly via a cover part 22 . Below the upper end region 5 , the sleeve 3 forms a peripheral shell 12 with a peripheral shell outer diameter 18 . Radial openings 14 are formed in the peripheral shell 12 . The radial openings 14 are separate...
