ABSTRACT:
An oil level control system uses an available pressure source to operate a fluid motor which is integrally connected with a reciprocating fluid pump. The pump has an inlet passage disposed at the desired oil level in a primary reservoir. A pair of one-way valves cooperate with the pump to draw oil, above the desired level, from the primary reservoir and deliver the oil to a secondary reservoir. A restricted drain back passage permits the fluid to return to the primary reservoir to ensure that the desired level is maintained. The fluid motor is connected with an accumulator such that the initial portion of the stroke is operated by the pressure source of the pump stroke. The motor is driven by pressurized fluid in the accumulator.
