A lubricant reservoir system includes a lubricant reservoir having an interior wall and an inlet for receiving lubricant from a supply. A follower device in the reservoir contacts the interior wall of the reservoir in a sliding and sealing manner, and the follower device is movable up and down in the reservoir from a first position to a second position in response to a changing lubricant level. A valve is in fluid communication with the inlet and is configured to selectively prevent a flow of the lubricant through the inlet. A connector operatively connects the follower device to the valve unit such that the flow of the lubricant through the inlet is prevented when the follower device is in the second position. The connector is configured such that the valve is positionable independently of the reservoir.

An aircraft engine oil filler apparatus includes a filler tube configured to be connected to an oil tank such that a bottom portion of the filler tube is disposed inside the oil tank, a valve received in the bottom portion of the filler tube movable between an open position in which the valve hydraulically connects the filler tube to the oil tank, and a closed position in which the valve hydraulically disconnects the filler tube from the oil tank, and a float disposed above the valve and operatively connected to the valve to move the valve from the open position to the closed position when oil inside the oil tank rises to a threshold level. The valve is movable independently from the float when pressure in the oil tank is greater than pressure in the filler tube. A method of operation of an oil filler apparatus is also described.

An automobile transmission hydraulic oil fill system includes a transmission oil pan and a two-piece standpipe system. The two-piece stand-pipe system includes a clinch nut connected to the oil pan and having a threaded bore opening through the oil pan. A stand-pipe is fixed to the clinch nut. The stand-pipe includes a longitudinal bore in fluid communication with the threaded bore. An end cap defining a free end of the stand-pipe prevents entrance of hydraulic oil into the longitudinal bore of the stand-pipe during hydraulic oil fill of the transmission. Multiple ports created in a side wall of the stand-pipe allow entrance of the hydraulic oil into the longitudinal bore and to flow out of the threaded bore of the clinch nut. Each of the ports include an edge. The edges of the ports define a hydraulic oil fill level of the transmission.

A lubrication pump assembly includes a fill tube and a sensor tube located within the fill tube. The sensor tube has a plurality of sensors disposed within the sensor tube and the sensors are configured to generate signals when triggered by a magnetic indicator, indicating a fill level of lubricant within the lubrication pump assembly. A follower within the lubrication pump assembly travels up and down within the lubrication pump assembly on a top of the lubricant. The fill tube is disposed between the sensor tube and the magnetic indicator.
