HYDRAULIC FLOW SUMMATION VALVE CONTROL SYSTEM

A vehicle includes a chassis and a hydraulic system. The hydraulic system is configured to facilitate operation of the vehicle. The hydraulic system includes a first hydraulic outlet (200), a second hydraulic outlet (300), a third hydraulic outlet (400), a first pump (104) configured to produce a first flow, a second pump (120) configured to produce a second flow, a priority valve (106), and a summation valve (130). The priority valve (106) includes a priority inlet (108) fluidly coupled to the first pump (104), a primary outlet (112) fluidly coupled to the first hydraulic outlet (200), and a secondary outlet (114) fluidly coupled to the second hydraulic outlet. The summation valve includes a summation inlet (132) fluidly coupled to the second pump, a return outlet (138) fluidly coupled to the priority inlet of the priority valve, an auxiliary outlet (140) fluidly coupled to the third hydraulic outlet (400), and a first control input (134) coupled to the secondary outlet (114) of the priority valve.
