摘要:
A motor control system for a lubricant pump motor comprises a pump system power input, a motor drive, a current sensor, a lubrication controller, and a drive controller. The pump system power input is configured to supply system power. The motor drive is configured to drive the lubricant pump motor using the system power. The current sensor is disposed between the pump system power input and the motor drive to sense an input current of the system power. The lubrication controller configured to provide motor activation signals. The drive controller is disposed to receive the motor activation signals via an isolated digital input, and to control the motor drive as a function of the sensed input current and a user-defined current set-point, in response to the activation signals.

The invention relates to a lubrication oil pump (1) for dosing a pre-settable amount of a cylinder lubrication oil (2) to a lubricating quill-opening of a cylinder of an internal combustion engine, in particular a two stroke large diesel engine. Said lubrication oil pump (1) comprising a housing (3) with a main hydraulic cylinder section (4) having a first axial end surface (5) and a second axial end surface (6), and further comprising a primary piston section (7) within the hydraulic cylinder section (4). According to the invention, the primary piston section (7) includes an injection bore (8) for receiving an injection piston (9) in such a way, that the injection bore (8) and the injection piston (9) arranged therein form a lubricating volume (V) for dosing the pre-settable amount of the cylinder lubrication oil (2) und are relatively movable with respect to each other along a cylinder axis (10). In addition, the invention relates to a cylinder lubricating arrangement and an internal combustion engine with a lubricating arrangement according to the invention.
