A device for passing lubricant out of a lubricant collecting container to a lubricant pump, in particular for an oil circuit of an internal combustion engine. The device including a lubricant intake pipe and a sedimentation container, which is connected fluidically to the lubricant intake pipe.

A battery cooling system includes: a circulation circuit configured to circulate common oil to a transaxle, a battery, and an oil cooler; a first electric oil pump that is disposed in a first oil passage; a second electric oil pump that is disposed in a second oil passage; and a controller configured to control the first electric oil pump and the second electric oil pump. The controller is configured to operate the first electric oil pump and stop the second electric oil pump when a temperature of the battery is equal to or lower than a first predetermined value, and stop the first electric oil pump and operate the second electric oil pump when the temperature of the battery is higher than the first predetermined value.

A transmission oil filter is assembled from a filter element, a base, and a cover. Each of the three pieces extends beyond the filtration media to form an inlet channel. The inlet channel is low enough to fit under a valve body. Placing the inlet in this channel ensures that the inlet draws transmission fluid at road gradients and acceleration rates at which an inlet under the filtration media would draw air.

This oil console device (24) is provided with: an oil tank (40) which recovers and stores lubricating oil which has lubricated a bearing portion supporting a rotating body; a pressure reducing fan (71) which is coupled to the oil tank (40) and which reduces the pressure inside the oil tank (40) such that the pressure becomes a negative pressure; an oil mist separator (50) which is provided on the oil tank (40) side of the pressure reducing fan (71) and which captures lubricating oil that has become a mist; and, on the downstream side of the pressure reducing fan (71), a exhaust unit (63s) which vents gas in the oil tank (40) to the outside.

A suction oil filter for a transmission or combustion engine including an oil filter housing made of plastic and having at least one suction channel that can be connected to a suction side of a suction pump and at least one return channel feeding into the suction channel for a pressurized oil flow returned by the suction pump. The return channel is provided with at least one nozzle in the region of the opening thereof into the suction channel, as well as at least one pressurized oil supply pipe which is linked to the return channel and can be connected to a pressure side of the suction pump, and which is connected to the oil filter housing via at least one contour connection.

An engine power unit for a vehicle has a crankcase made up of tow left and right crankcase members, and a lubricant feed pump disposed in one crankcase member in such a fashion that one side surface of pump rotors of the feed pump lies on the mating surface of the crankcase members. The feed pump is mounted on one end of the shaft of the feed pump while a drive gear for rotating the shaft is disposed on the opposite end of the shaft. A lubricant oil filter to which oil is delivered from the feed pump is disposed on the other crankcase member. Thus, the structure for supplying lubricating oil is simplified, and the power unit is reduced in size in its entirety.

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.
