Embodiment Construction

[0029] exist figure 1 A cylinder oil metering pump according to the invention is schematically shown in . Cylinder oil dosing pump 1 for dosing a presettable amount of cylinder lubricating oil 2 to the lubricating sleeve of the cylinder of an internal combustion engine, comprising an actuating piston 3, a dosing plunger 4 driven by the actuating piston 3 in the operating state , and a conveying device 5 for conveying the lubricating oil 2 via the dosing space 6 to the lubricating sleeve, the lubricating sleeve is arranged on the cylinder wall of the cylinder of the internal combustion engine. In the dosing space 6 a dose plunger 4 is drivable, which is arranged to be reciprocable on a working stroke along a plunger axis 7 in delivery and return strokes. The conveyor device 5 is a hollow conveyor device 5 having a two-part design. The first part of the transfer device 5 is a switch part 51 which is movably arranged in a transfer part 52 which is the second part of the transfe...

Abstract

The invention relates to a cylinder oil dosage pump (1) for dosing a presettable amount of a cylinder lubricating oil (2) to a lubricating quill of a cylinder of an internal combustion engine, in particular a two stroke large diesel engine. The cylinder oil dosage pump (1) comprises an actuating piston (3), a dosage plunger (4) and a delivery means (5). According to the invention, the delivery means (5) is a hollow delivery means (5) of a two-part design, including a switching member (51) and a delivery member (52). The switching member (51) is movable arranged within the delivery member (52) so as to reciprocate between a filling position (5101) and a delivery position (5102), wherein in the filling position (5101) the dosing space (6) is refillable with lubrication oil (2) via a lubricating oil supply-opening (8) and in the delivery position (5102) the lubricating oil (2) is deliverable by means of the dosage plunger (4) via a quill-opening (9) to the lubricating quill. In addition, the invention relates to a cylinder lubricating arrangement and an internal combustion engine with a lubricating arrangement according to the invention.

Description

technical field [0001] The present invention relates to a cylinder oil dosing pump for dosing cylinder lubricating oil into lubricating quills of cylinders of internal combustion engines, especially two-stroke large diesel engines operating at low speeds, and to a pump comprising oil dosing Cylinder lubricating device of a pump and an internal combustion engine according to the preambles of the respective independent claims. Background technique [0002] Large diesel engines are frequently used as power units for ships or, in stationary operations, for example, to drive large generators that generate electrical power. Here the engine is generally in continuous operation for a relatively long period of time, which places high demands on operational reliability and availability. For this reason, long maintenance intervals, a low degree of wear and especially economical use of fuel and operating materials are central principles for the operation of the machine for the operator...
