In a rotary electric machine housing, a first bearing and a second bearing are provided for supporting a rotating shaft. A lubricating oil is supplied to the first bearing and the second bearing. Further, a gas is supplied to the first bearing and the second bearing. The lubricating oil and the gas are recovered by a single recovery device.

An oil distribution system uses an oil storage container to contain an air/oil separation unit, a heat exchanger, and an oil reservoir. The functions of oil storage, air/oil separation, and cooling are integrated in the container. Hot aerated oil enters the container at an air/oil separation unit. The air/oil separator deposits hot de-aerated oil into the oil reservoir. The oil reservoir transfers hot de-aerated oil to conduits in a heat exchanger. The heat exchanger uses fuel to cool the oil and warm the fuel. Cooled de-aerated oil is provided to a mechanical device for lubrication and warmed fuel is provided to power an engine. The container may alternatively receive hot aerated oil into the conduits in the heat exchanger. Cooled aerated oil is delivered to the air/oil separation unit to deposit cooled de-aerated oil into the reservoir. Cooled de-aerated oil is pumped to a mechanical device to provide lubrication.

An oil tank system (100) for a gas turbine engine is provided. The oil tank system (100) includes an oil tank (102) having an upper tank portion (112) and a lower tank portion (114), a waisted section (118) being provided between the upper tank portion (112) and the lower tank portion (114). Oil is received by a de-aerator (104) of the system (100) which supplies de-aerated oil to the upper tank portion (112). The waisted section (118) includes an upper face (119) configured to catch oil drips from above the waisted section (118) and to guide oil to a lower face (121) of the waisted section (118).

A lubrication system for an aerial vehicle, the lubrication system including: a lubrication oil (LO) tank configured to operate at a first internal pressure; and an intake chamber (IC) configured to operate at a second internal pressure greater than the first internal pressure, the IC including an ingress port configured to receive LO from a sump of an equipment of the aerial vehicle; an overflow port in fluid communication with the LO tank; and a supply port in fluid communication with the sump and configured to supply LO to the sump.

A reciprocating internal combustion engine includes at least one piston, which is operatively connected by two connecting rods having two crankshafts rotating in opposite directions and running parallel to each other, which crankshafts are oriented in an upright manner to a horizontal water line of a boat, and an internal combustion engine housing of the internal combustion engine is composed of at least a cylinder crank housing and a cylinder head, having inlet and outlet valves, and is bounded by an upper end face and a bottom end face. To optimize the internal combustion engine, a joint ventilation system has an oil separating device provided with an oil pre-separator and a main oil separator, via which, when operating the internal combustion engine, a mixture of oil and leaking gas, resulting in a crankcase of the cylinder crank housing, reaches, by way of a discharge line extending adjacent to the upper end face, the oil pre-separator, from where the mixture of oil and leaking gas is led into the main oil separator and there is separated into the components of oil and leaking gas. The oil flows into an oil pan connecting at the bottom end face and the leaking gas near the upper end face flows into an intake system of the internal combustion engine.
