ABSTRACT:
A lubricating device for use with transmission gearing, particularly in the starting phase of the transmission. A pair of oil reservoirs are provided with one being located higher than the other. The upper reservoir contains the transmission gearing therein. A pair of vertically spaced outlets are provided in the upper reservoir with both outlets being connected in fluid circuit with the lower reservoir. The fluid circuit for the lower outlet includes a valve controlling the flow of oil between the upper and lower reservoirs in response to the fluid pressure produced by a pump. The transmission gearing is immersed in the oil when the lower outlet is blocked by the valve, which will occur when the pump is off. When the pump is activated, the valve is opened in response to the pressure produced by the pump and the oil level in the upper reservoir will drop due to a gravity feed thereof to the lower reservoir through the valve to the level of the lower outlet so that the gearing will no longer be immersed in oil. By this time, however, the pump will be supplying adequate oil to lubricate the transmission gearing through a nozzle arrangement. The volume of oil in the nozzle arrangement is sufficient, when the pump is deactivated, to fill the upper reservoir up to the upper outlet level to again immerse the gearing in oil in readiness for a new start-up operation for the transmission gearing.
