An oil tank assembly for a gas turbine engine may include an oil tank having an upper compartment and a lower compartment. A baffle may separate the upper compartment of the oil tank from the lower compartment of the oil tank. A de-aerator may be included, where the de-aerator includes an oil inlet, a de-aerator outlet, and an air vent. The de-aerator may be configured to separate air from oil in an air-oil mixture such that the oil flows through the de-aerator outlet and such that the air flow through the vent. Further, the de-aerator may include a fill port for receiving oil.

A lubrication system for an aircraft engine includes an engine lubricant tank including at least a supply port hydraulically connectable to the aircraft engine, a lubricant makeup port, and an overfill port, an auxiliary lubricant tank, a lubricant makeup conduit hydraulically connecting the auxiliary lubricant tank to the lubricant makeup port. The lubricant makeup conduit includes a pump operable to move lubricant from the auxiliary lubricant tank to the lubricant makeup port, and an overfill conduit hydraulically connecting the overfill port to the auxiliary lubricant tank. A method of operating a lubrication system of an aircraft engine of an aircraft is also disclosed.

The blow-by gas treating device 100 has a main structure portion 101 which separates oil OL from the blow-by gas BG and an outlet portion 40 which supplies gas G having been separated from the blow-by gas BG to an intake system. The main structure portion 101 has a first blow-by gas taking-in portion 111, a second blow-by gas taking-in portion 112, a separating portion 330 which separates the blow-by gas BG into oil OL and gas G, a first oil guiding portion 151 which guides the oil OL to a front side, a second oil guiding portion 152 which guides the oil OL to a rear side, a first oil drain 161 which discharges the oil OL into the engine, and a second oil drain 162 which discharges the oil OL into the engine.

A powertrain arrangement for a transverse mounted motor for an electric powered automotive passenger vehicle including opposing wheel shafts for powering two parallel mounted wheels, the shafts rotating about a first axis, the shafts having at least one end torsionally connected with a differential, an electrical rotor torsionally connected with the wheel shafts via a planetary gear train, an electrical stator surrounding the rotor, a casing supporting the rotor and the wheel shafts, the casing encompassing the stator, the casing having a floor forming a lubricant reservoir, and a baffle located in the lubricant reservoir. The baffle forming a wall with a portal allowing flow through the formed wall, and wherein an increase of fluid pressure throttles flow through the formed wall.

A lubricant pan for a vehicle includes a receiving region in which a lubricant is at least temporarily receivable, a first wall element, and a second wall element. A temperature-control channel is disposed between the first wall element and the second wall element and a temperature-control medium is flowable through the temperature-control channel. A core that is porous and permeable to the temperature-control medium is disposed in the temperature-control channel between the first wall element and the second wall element. The temperature-control medium is introducible into the temperature-control channel via a first connector and the temperature-control medium is dischargable from the temperature-control channel via a second connector.

A storage reservoir for an internal combustion engine is provided that includes a plurality of vents connected to an air compartment that outlets air from the storage reservoir. The storage reservoir can remain vented to supply of lubrication fluid even if the internal combustion engine is inclined due to operation along severe grades.

An electric oil pump includes a motor part having a shaft; a pump part that is positioned on one side of the motor part and is driven by the motor part via the shaft and discharges oil; and a control part configured to control an operation of the motor part, wherein the motor part includes a rotor, a stator disposed to face the rotor, and a motor housing, wherein the pump part includes a pump rotor and a pump housing having a housing part, wherein the control part includes a plurality of electronic components and a board, the plurality of electronic components include a heat generating component, wherein the motor housing has a cylindrical part and a plurality of heat dissipating fins that extend from the cylindrical part, wherein the board has a first surface and a second surface, and the heat generating component is mounted on the second surface.

The present disclosure describes an oil pan structure including a storing portion that stores oil for an internal combustion engine. The storing portion includes a shallow bottom portion, a deep bottom portion deeper than the shallow bottom portion, and a connection surface that connects the shallow bottom portion and the deep bottom portion between the shallow bottom portion and the deep bottom portion. A side wall is formed at a position facing the connection surface with the shallow bottom portion interposed between the side wall and the connection surface. A rib is formed on a back surface of the shallow bottom portion so as to extend from one side or another side of the side wall in a width direction of the shallow bottom portion toward an end portion of the connection surface on an opposite side in the width direction.

A diffuser for an oil drainback system drain tube includes a flow chamber configured for attachment to an open end of a drain tube, wherein the flow chamber has a side wall and an end wall, and openings in at least the side wall.
