Abstract
Hydraulically operated steering systems normally supplied with fluid from an engine driven pump rely on an auxiliary pump upon failure of the primary pump. A ground driven pump incorporating a pressure sensing device automatically provides fluid to the power steering system in the event of an engine or primary pump failure.
