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 casing (20) housing a filter (10) includes a sealing portion (43) for sealing a gap between an upstream space (R1) and a downstream space (R2). The sealing portion (43) has a bridge shape separated from a wall surface of the oil channel and extending across the channel.

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 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.

In variable displacement engines, a portion of the intake valves have deactivatable valve lifters. When the engine conditions are such that some of the cylinders are to be deactivated, the intake and/or exhaust valve lifters in those cylinders are deactivated. Operation of the mechanism inside the lifter that is actuated to deactivate the valves can be harmed when particles in the engine oil get inside. To prevent small particles entering the valve lifter, a small filter is provided just upstream of the orifice into which oil enters the valve lifter. In other embodiments, a wire mesh formed into a coil is inserted into the recess. In some applications, a cage with snap-fitting connectors is installed over the filter to keep the wire mesh in place and properly coiled. The cage also fits into the recess. Such filter may also be applied to a hydraulic lash adjuster feature in a lifter.

A combined oil filter and restrictor assembly is disclosed having an oil flow restrictor interposed between first and second filters so that, irrespective of the direction of oil flow through the restrictor, debris cannot enter a small diameter bore 32 in a body of the restrictor thereby reducing the likelihood of restrictor blockage. The combined oil filter and restrictor assembly includes a metal threaded member that enables the combined oil filter and restrictor assembly to be easily and quickly assembled to or removed from a component such as a cylinder head of a variable displacement engine. The combined oil filter and restrictor assembly can be used to provide a restricted flow of oil from oil supply passages to signal oil passages used for controlling the operation of deactivatable hydraulic lash adjusters so as to purge the signal oil passages when the deactivatable hydraulic lash adjusters are not deactivated.

Vehicles or machinery equipped with full flow spin-on, canister or reusable filters can benefit by including advanced or bypass grade parallel filtration. Incorporating advanced filtration is generally difficult due to impractical lubrication system access, cramped engine bays, and some installation solutions require engine modifications and hardware. An apparatus of the present invention provides advanced filtration when used inside well-known manufactured forms of spin-on, cartridge, or reusable filters. The unit installs as a complete unit, without modifications, or external hardware to any engine at the spin-on filter point of attachment, inside the canister housing, or inside a reusable filter form. The apparatus uses the structures of the normally provided filter to enable a bolt-on installation. The apparatus increases filtration efficiency, capacity, easier maintenance, while providing environmental benefits.

An engine includes a crank shaft inside a crankcase and an oil pan and penetrates the crankcase and the oil pan in an up-down direction. An oil pump and an oil strainer are provided inside the oil pan. The oil pump is coaxial with the crank shaft and is driven by the crank shaft. The crank shaft includes a first region and a second region respectively supported pivotably by a plate-shaped support and the crankcase. The support is provided in the crankcase such that both surfaces of the support are covered by the crankcase and the oil pan and allows communication between the crankcase and the oil pan.

An oil recirculation system for an engine is disclosed. The oil recirculation system includes a first conduit coupled to the engine to receive an oil and a second conduit coupled to the engine to supply the oil to the engine. The oil recirculation system further includes a filtering device disposed between the first and second conduits. The filtering device includes a first housing member defining a first chamber therein. The first chamber is in fluid communication with the first conduit. The filtering device further includes a second housing member removably coupled to the first housing member and defines a second chamber therein. The second chamber is in fluid communication with the second conduit. The first and second chambers together define a passage to receive the oil therethrough. The filtering device further includes a filter member disposed in the passage to filter the oil flowing therethrough.

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.
