Abstract:
PCT No. PCT/EP94/02836 Sec. 371 Date May 5, 1995 Sec. 102(e) Date May 5, 1995 PCT Filed Aug. 26, 1994 PCT Pub. No. WO95/07399 PCT Pub. Date Mar. 16, 1995A one-piece terminal block (73) is provided as a hydraulic linking element as well as a mechanical carrier for control valves (68 to 72) of a boom control unit, for an operating mode selector valve (74), and for switching elements of a pressure supply device (77). A pressure line (119), return line (132), control line (166), and a further return line (167,168) are designed as bores extending in an axial direction of the terminal block, from which connection channels originate which terminate within terminal arrays (163, 163I to 163IV) in a bore layout for the valves. Sections (102') of a load feedback line (102), which are serially connectable to each other by comparative valves (114) are formed by individual longitudinal bores (188,188I to 188IV) introduced into the terminal block (73) from its free end (164) and plugged there, as well as by cross-channels connecting these longitudinal bores individually to a load-comparative output (117) of one of the comparative valves as well the load-comparative input (116) of an adjacent comparative valve.
