The invention relates to a cleaning device (10) for liquids, in particular for oil based liquids, and comprises a housing (12), which contains liquid or through which liquid flows, and at least one cleaning body (16), which is accommodated within the housing (12) and to which the liquid can be supplied, and the material of the cleaning body (16) is designed such that impurities contained in the liquid can be introduced and absorbed therein. The cleaning body (16) is attached in a cover (13) of the housing (12).

An oil filter arrangement for filtering oil of a vehicle can comprise: at least one filter unit for filtering the oil, and at least one connection unit comprising at least one inlet tube configured to be connected with an outlet tube of a separate oil pump, wherein the oil filter arrangement is configured to be housed in an oil filter arrangement housing of the vehicle.

A power unit including an internal combustion engine has an electric power generator mounted on an end of a crankshaft, a power transmitting member mounted on the other end of the crankshaft, and a lubricant oil filter. The oil filter partly overlaps the electric power generator as viewed in the direction of a crankshaft axis, and is positioned between the electric power generator and a crank weight on the crankshaft with respect to the direction of the crankshaft axis. The oil filter has a filter mount axis forming an acute angle to the crankshaft axis. The engine crankcase is thus prevented from bulging outwardly, and the power unit is reduced in size in its entirety.

A filter configured to replace an original filter disposed in a cavity in a transmission, increases fluid flow rate through the filter. An example filter includes a bottom structure configured to mate with the bottom portion of the cavity, and the bottom structure defines an outlet through which oil passes from the cavity to the outlet of the housing. The filter also includes a filter media having a bottom portion and an opposite top portion, the bottom portion being coupled to the bottom structure of the filter. In the example filter system, the outer diameter of the bottom portion of the filter media is greater than the outer diameter of the top portion of the filter media.
