Abstract: A distributed system for draining and filling oil reservoirs in engines includes an electrically powered reversible pump, a relocated oil filter, a shutoff valve and a plurality of hoses to direct oil through the pump and valve to drain or fill the engine. The pump, valve and oil filter are located remote from each other preferably adjacent the top of the engine to be readily accessible from above without lifting the vehicle.

Abstract: A distributed system for draining and filling oil reservoirs in engines includes an electrically powered reversible pump, a relocated oil filter, a shutoff valve and a plurality of hoses to direct oil through the pump and valve to drain or fill the engine. The valve and oil filter are located remote from each other preferably adjacent the top of the engine to be readily accessible from above without lifting the vehicle. The fluid and electrical connections to the pump include quick connect fittings that allow for the use of a portable pump to which temporary connections are made.

Abstract: An alarm system to warn those pumping fuel into remote tanks that the fuel level is at the top of the tank, and thus prevent overflowing. This system is particularly useful for filling tanks in boats.

Abstract: A system for draining and filling oil reservoirs in the crankcases and the generators of marine vessels with at least one or two diesel engines, including a motor driven pump, conduits connecting the pump to the reservoirs of the generator and of each engine and with the fuel tanks, an oil sump of fresh oil, and selector valves to connect the conduits to the pump in a variety of combinations; one of which extracts used oil from the reservoirs and forces same through a filter/blender while receiving diesel fuel from a tank on board the vessel and returns the mixed used oil and fuel to the tank for subsequent combustion by the engine; a second of which provides fresh oil to the reservoirs; and a third of which provides diesel fuel to the tanks.

Abstract: A system for draining and filling oil reservoirs in the crankcases and the transmissions of vehicles with two or more engines, including a motor driver pump, conduits connecting the pump to the crankcases and transmissions of each engine, the generator, and an oil sump; and selector valves to connect the conduits to the pump in a variety of combinations.

Abstract: A reversible fluid pump is driven by a reversible electric motor under the control of a three position toggle switch wired for off, forward and reverse. One port of the pump is connected to a four position valve, one position of which is off. A hose to a drain receptacle or to an oil supply connects to the other port of the pump and hoses from engine crankcases connect to the three active ports of the valve. A two position valve adapts the pump for single engine use. The handle for selectively positioning each of the valves extends perpendicularly to the valve stem and when in off position aligns with the toggle. Safety latches of alternate constructions, with or without thumb screw tightening means, are each pivoted to the handle to engage the toggle and retain both the valve and toggle in off position when the system is not in use.
