An internal combustion engine is provided, including at least one crankcase, at least one oil pump, at least one oil filter, at least one oil circuit, at least one control valve, and at least one device for separating particulate contaminants from a fluid flow, in particular for separating contaminants from the crankcase of the internal combustion engine, this fluid or oil flow to be purified having at least one containment for receiving the contaminants.

An oil tank (100) for a gas turbine engine is provided. The oil tank (100) comprises an oil inlet (102), an oil outlet (104), and a body including a coiled portion (106) interposed between the oil inlet (102) and the oil outlet (104). Oil is received by the coiled portion (106). The coiled portion (106) acts to at least partially de-aerate oil received from the oil inlet (104).

A fluid delivery system for supplying fluid to at least one machine assembly, in particular an engine and/or transmission of a motor vehicle, including: a first pump and a second pump; a drive for driving the first pump and/or the second pump; a reservoir for storing the fluid; and a filter module for filtering the fluid, wherein the first pump delivers fluid from the reservoir to the machine assembly in a supply flow and the second pump is arranged downstream of the machine assembly and delivers at least some of the fluid into the reservoir in a sub-flow downstream of the machine assembly and the filter module is embodied in the sub-flow.

A fluid delivery system for supplying fluid to a machine assembly includes: a pump module; a drive for the pump module; and a housing which includes a reservoir for the fluid. The reservoir includes an aspiration point, and the pump module includes a first inlet, a second inlet, a first outlet and a second outlet. The first inlet is fluidically connected to the reservoir via a first suction conduit, and the first outlet is fluidically connected to the machine assembly via a first pressure conduit. The second inlet is fluidically connected to the housing via a second suction conduit, and the second outlet is fluidically connected to the reservoir via a second pressure conduit.

Lubricant consumer system comprising at least one lubricant consumer, at least one rotating component, wherein fluid lubricant can be conveyed via the rotating component, and a lubricant distributor system, wherein the lubricant distributor system has at least two lubricant tanks, namely a first lubricant tank and at least one second lubricant tank, and a lubricant channel, wherein the two lubricant tanks are fluidically connected to one another and to the lubricant consumer via the lubricant channel, wherein one of the two lubricant tanks is designed and arranged in such a way that, in a horizontal position of the lubricant consumer system, it receives the fluid lubricant of the rotating component and supplies both the other lubricant tank and the lubricant consumer with lubricant via the lubricant channel, and wherein the other lubricant tank is designed and arranged in such a way that, in an inclined position of the lubricant consumer unit, the lubricant consumer is supplied with lubricant from at least the other lubricant tank.

An internal combustion engine includes an engine lubrication fluid storage system with a primary storage volume and a secondary storage volume that is separate from the primary storage volume. The secondary storage volume is linked to the primary storage volume with a fluid flow path that is throttled so that lubrication fluid is stored in the secondary storage volume during engine operation, and drains from the secondary storage volume to the primary storage volume when the engine is not running.

An internal combustion engine is provided with oil intake pipes defining oil inlets on both sides of a tunnel type sump. Each oil intake pipe includes a valve which is operable to close the respective flowpath when the respective sump portion is tilted upwardly about the length axis of the engine. The inlets may be arranged to remain submerged in a minimum quantity of oil which is retained in each sump portion while the engine is tilted through its maximum angular range about both length and width axes.

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 hydraulic control system includes a primary sump and an auxiliary sump. When the transmission fluid is warm, fluid remains in the auxiliary sump reducing the volume of oil in circulation throughout the transmission to reduce parasitic losses. An oil control valve is designed to block flow of oil from the auxiliary sump to the primary sump when the fluid is warm and to allow flow when the fluid is cold. The oil control valve also responds to transmission line pressure. At moderate temperatures, fluid is held in the auxiliary sump when the engine is running but drains back to the primary sump when the engine is off.
