Abstract:
A valve includes a bore within a valve body having a central axis. A plurality of galleries in the bore define flow paths for hydraulic fluid. A spool is positioned in the bore, and the spool is moveable along the central axis between a first position in which hydraulic fluid from a central pump gallery is prevented from flowing to first and second working galleries and from flowing to one or more tank galleries; a second position in which hydraulic fluid from the central pump gallery is in fluid communication with both the first and second working galleries simultaneously; and a third position in which the first and second working galleries are in fluid communication with the one or more tank galleries simultaneously.
