Abstract

1512255 Valves SCHWELM & TOWLER HYDRAULICS GmbH 4 July 1975 28308/75 Heading F2V Each segment 1 of a series of stacked segments forming a multi-way valve block comprises main valves 10 to 14 mounted in transverse bores within the segment and controlled by pilot valves 20, 21 secured to the outer walls of the segment. Each main valve 10 to 14 comprises a closure member 16 biased by spring 17 towards a seat on sleeve 15, pilot fluid being supplied to or vented from chamber 22 under the control of valves 20, 21. Adjustable limit stops 18, 19 are provided for main valves 10, 11. The segment 1 includes passages 5, 8 connected with tank and a pressure source respectively. Main valve 14 acts to reduce the pressure from source 8 under the control of pilot valve 21. The segments may be secured together by screws or pull armatures to form the complete block.
