ABSTRACT:
A power fluid system for a vehicle embodying a two-fluid pump which utilizes an existing source of fluid under pressure is provided. The existing source of fluid enables a second source of fluid under pressure to be established through the two-fluid pump. Vehicles often require high pressure fluid to operate auxiliary equipment such as traction or anti-skid units, limited-slip differentials, and hydraulic load-leveling systems. More specifically, the two-fluid pump is a linear pump operated by fluid under pressure from the power steering pump of the vehicle. The two-fluid pump can supply a different fluid under higher pressure for the auxiliary equipment, as required. The pump is pulse cycled quickly to provide adequate quantities of both sources of fluids with the use of small capacity accumulators.
