Abstract
A load sensitive hydraulic system for operating auxiliary equipment on a vehicle with a priority flow control valve to provide priority pressure in operating a regenerative steering circuit of the hydraulic system. The regenerative hydraulic steering circuit provides load sensing and utilizes single source of pressurized fluid which responds to various loads in the hydraulic system. A priority valve assures that the steering demands are met before providing adequate pressure for all other auxiliary functions.
