The invention further relates to a method for off-line filtering of contaminated oil from diesel machinery (1).

Provided is an electric oil pump that does not degrade assembly operability and does not require a complicated configuration. The electric oil pump includes a motor portion that has a motor shaft disposed along a center axis extending in an axial direction; a pump portion that is disposed on one side of the motor portion in the axial direction, is driven by the motor portion via the motor shaft, and suctions and ejects an oil, and an inverter portion that is disposed on one side of the pump portion in the axial direction and drives the motor portion, the motor shaft penetrates through the pump portion, and the electric oil pump further includes a rotation angle sensor that is disposed at the inverter portion and detects a rotation angle of the motor shaft.

In one embodiment, there is provided a device for a vehicle, having: a first interface configured to couple to at least one replaceable fluid container for a vehicle comprising a battery, the first interface comprising at least one fluid port configured to couple to at least one fluid port of the replaceable fluid container; a second interface configured to couple to an engine of the vehicle, the second interface comprising at least one fluid port configured to couple to at least one fluid port of a fluid circulation system of the vehicle; a fluid path coupled to at least one fluid port of the first interface and at least one fluid port of the second interface; and at least one electrical pump configured to be powered and/or driven by the battery of the vehicle and to cause fluid flow.

A mobile vehicle lubrication unit for serving power transmission equipment elevated above ground level such as conveyors whereby the lubricant containing gear reducer unit is disposed in an enclosed body mounted on an upper portion of an elevated conveyor. The system includes a manifold system connectable to trailer mounted storage tanks for lubricants, pumps, filters, air supplies and supply lines, and transfer means mounted on a truck or trailer including side access to the control panel and transfer hoses enabling the user to transfer lubricants to elevated equipment such as conveyors by pulling along side of same. The device changes, filters, and replaces the oil in a reducer gearbox or other lubricant containing equipment which is not easily accessed from the ground level. Air presssure is used to evaculate used oil from the conveyor gear motor and/or reducer units and replaces the used oil with filtered or new oil through oil lines and hoses with quick disconnects which may be positioned on a manifold at ground level having oil lines in fluid communication with the gear motor/reducer unit.

An oil separator unit including an upstream member having an opening through which the blowby gas passes, a downstream member having a hit portion hit by the blowby gas, and a porous member trapping the oil mist contained in the blowby gas that has passed through the through hole. The upstream member includes and a spacer projected from an upstream surface facing a first surface of the porous member to support the first surface, the downstream member includes a rib projected from a downstream surface facing a second surface of the porous member to support the second surface, and the spacer is extended along a first direction and the rib is extended along a second direction substantially perpendicular to the first direction.

An oil separator unit including an upstream member having an opening through which the blowby gas passes, a downstream member having a hit portion hit by the blowby gas, and a porous member trapping the oil mist contained in the blowby gas that has passed through the through hole.
