Abstract
According to the invention, there is provided a power control system designed to effectively utilize the output power of an engine with the aid of a simple tilt control device, even if any of the pumps are operated under a no load condition. The control system comprises a pressure selector valve with the output pressures of two variable volume pumps of the same capacity being fed thereto, the lower output pressure being selected by the selector valve and introduced to a pilot portion of a tilt control of at least one of the other variable volume pumps, the output pressure of which is fed either directly or through another pressure selector valve to a pilot portion of at least one of the variable volume pumps of the same capacity, thereby controlling the power of the multiple pumps.
