ABSTRACT:
A hydraulic system with a valve for controlling fluid flow to the two reversible hydraulic wheel motors in a hydrostatic drive vehicle includes a pair of valve spools axially slidable in bores in a valve body. Each spool has a pair of opposed notches. In one position of the spool, the notches provide separate paths for dual input flows to each of two passages to the wheel motors which differentially lock the wheel motors. In a second position, the notches act to exhaust the return flows in two passages to a single exhaust.
