ABSTRACT:
This invention relates to an arrangement for communicating fluid between a pressurized source and an implement that is remotely mounted on a linkage arrangement of a construction machine. The conduit arrangement includes a pair of conduits positioned internally within the linkage arrangement. One conduit communicates the pressurized fluid to a control valve mounted on the end of the linkage, while the second returns the fluid to a reservoir. This arrangement permits a plurality of conduits to extend between the control valve and a multi-function implement mounted on the linkage arrangement while limiting the number of conduits between the control valve and the source of pressurized fluid.
