ABSTRACT:
A hydraulic fluid flow network, utilizing the fluid returned from by an open center hydraulic system, to augment the charging system of a hydrostatic transmission. The augmented charging system provides oil under pressure to flow into the charging system in the event that charging system pressure flow falls below normal. A back pressure is maintained in the return line header of an open center hydraulic system by a relief valve. Flow is diverted to the charging system by a line containing a non return valve.
