A separating device for separating an undesired fluid from a multi-component liquid has a region flowed through by the multi-component liquid and at least one membrane disposed in the region to separate a first fluid region from a second fluid region. The membrane has a first permeability to the undesired fluid and a second permeability to the multi-component liquid. The first permeability is different from the second permeability. The membrane is equally permeable to all components of the multi-component liquid. The membrane is permeable to the multi-component liquid and impermeable to the undesired fluid, or the membrane is impermeable to the multi-component liquid and is permeable to the undesired fluid, wherein the multi-component liquid is a liquid multi-component operating medium. A filter with such a separating device and a filter element, in particular for diesel fuel, as well as a liquid system with such a separating device are described.

A lubrication system for extending times period between changing engine lubricant may include a tank and a lubricant exchange apparatus. The lubricant exchange apparatus may comprise a first pump in fluid communication with the engine and the tank to transfer lubricant from the lubricant collection element to the tank, a second pump in fluid communication with the tank for transferring lubricant from the tank to the engine, and a control element configured to cause the first pump to operate to remove lubricant from the lubricant collection element. The control element may be configured to cause the second pump to operate to remove a quantity of lubricant from the tank and transfer the quantity to the engine.

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.

A magnetic device for capturing metal wear particles in suspension in a lubrication fluid, the magnetic device being for inserting in a straight-line insertion direction of the magnetic device into a wall of a casing via a through orifice serving to put an inside volume of the casing containing the lubrication fluid into communication with an outside volume outside the casing, the magnetic device presenting a longitudinal axis X, the longitudinal axis X being for putting into coincidence with the direction for inserting the magnetic device into the casing, the magnetic device comprising a permanent magnet suitable for attracting the metal particles and a presence-detector member for detecting the metal particles attracted by the permanent magnet.

A contamination removing device for removing a contamination from oil for lubricating a rolling bearing supporting a rotary shaft of a turbocharger includes a body portion including an oil channel for the oil to flow, and a contamination removing element for removing the contamination from the oil flowing through the oil channel, the contamination removing element being provided in the oil channel. The body portion is configured to be detachable from the housing so that the oil channel and an oil supply channel for the oil to flow communicate with each other, the oil supply channel being formed in a housing of the turbocharger.

An internal combustion engine which can be miniaturized, even where it includes an oil filter between a hydraulic clutch and an oil pump, without significantly increasing the length of an oil passage for the hydraulic clutch, the oil pump and a hydraulic pressure adjustment apparatus. A second oil filter is provided on an oil pan at a lower portion of the internal combustion engine so as to be disposed at a position at which the second oil filter does not overlap with any of a controlling oil pump and a hydraulic pressure adjustment apparatus as viewed in side elevation and which is lower than those of the oil pump and the hydraulic pressure adjustment apparatus.

A contamination removing device for removing a contamination from oil for lubricating a rolling bearing supporting a rotary shaft of a turbocharger includes a body portion including an oil channel for the oil to flow, and a contamination removing element for removing the contamination from the oil flowing through the oil channel, the contamination removing element being provided in the oil channel. The body portion is configured to be detachable from the housing so that the oil channel and an oil supply channel for the oil to flow communicate with each other, the oil supply channel being formed in a housing of the turbocharger.

An oil filter assembly for an integrated drive generator is disclosed, which includes an elongated cylindrical filter element having opposed upper and lower end portions, a longitudinal axis, an outer diameter and an inner diameter, wherein the oil filter assembly that includes the filter element has an axial length that is greater than 4.60 inches.

A filter element assembly comprises a filtration media and an end fitting through which a sealing connection is made between the assembly and a housing so that the end fitting defines a flow path between the housing and the filtration media. The end fitting has first and second parts which can be separated axially, and the filter media extends axially away from the second part in a direction away from the first part. Each of the parts has an outer wall with an external threaded cylindrical surface, and each of the first and second parts has an axially facing edge surface which faces the other of the first and second parts, the facing edge surfaces shaped to define a pre-determined relative rotational alignment of the first and second parts, where the parts fit together so that the threads on the external surfaces of the parts form a continuous thread.
