Description
DESCRIPTION The invention relates to a device for lubricating the cylinders of a reciprocating piston internal combustion engine, in particular a longitudinally flushed, long-stroke two-stroke diesel engine, with a plurality of lubricant nozzles on each cylinder, distributed over its circumference and connected at the same height and opening into the cylinder running surface, with a piston on each lubricant nozzle. Cylinder system is connected, which draws in lubricant via a suction valve and conveys it to the associated lubricant nozzle via a pressure valve. In a lubricating device of this type, the piston-cylinder systems are driven by a camshaft which has as many cams as there are piston-cylinder systems, a pivotable lever being arranged between each cam and the associated system. The camshaft is coupled synchronously with the crankshaft of the internal combustion engine, which has the disadvantage that the location of the lubrication device is tied to the local position of the crankshaft. The mentioned pivotable lever between the cam and the associated piston-cylinder system serves to vary the delivery rate of the lubricant, which is cheap in itself, but has the disadvantage that at the same time the start of delivery changes unintentionally. Overall, the known lubrication device is also structurally very complex. The invention has for its object to improve the lubrication device of the type mentioned so that it can be arranged regardless of the position of the crankshaft of the reciprocating internal combustion engine on this and the delivery start can be varied in the desired manner with a reduction in the design effort. This object is achieved according to the invention in that the piston-cylinder systems of each cylinder have a common drive which is acted upon by a hydraulic or pneumatic pressure medium and that a control device is present which controls the pressure medium supply to the common drive in such a way that the lubricant is pumped into the associated cylinder at intervals when the piston in the cylinder with its rings comes into the area of the lubricant nozzle during the working stroke. Because the piston-cylinder systems have a common drive acted upon by a pressure medium, there is greater freedom in the spatial arrangement of the lubricating device, since this arrangement is no longer tied to the position of the crankshaft and / or any camshafts. This results in a significant design simplification. In addition, it is possible with the new lubrication device to vary the start of delivery as desired. An embodiment of the invention is explained in more detail in the following description with reference to the drawing. Show it: Fig. 1 shows a schematic representation of a lubrication device according to the invention and Fig. 2 shows schematically the arrangement of the lubricant nozzle on a cylinder. 1, the lubrication device has a high tank 1, in which a lubricating oil supply is stored. A pump 2 is connected to the high tank 1 and conveys lubricating oil from the tank 1 to a distribution line 3, from which as many lines 3 'branch as the reciprocating piston internal combustion engine (not shown) has cylinders. The pressure of the lubricating oil in the distribution line 3 is maintained with the aid of an overflow valve 4, which allows excess lubricating oil to flow back into the high tank 1 via the line 4 ′. In the uppermost line 3 'in FIG. 1, a flow control device 5 is arranged, which contains a piston valve 6 in a transparent housing, which is loaded by a square weight. Lubricating oil can only flow through the flow device 5 if the piston valve has been lifted sufficiently from its valve seat. The lifting is visible from the outside, and a proximity switch 7 above the control device 5 reports the lifted state of the piston valve 6 via a signal line 7 'to a monitoring unit, not shown. The line 3 'leads from the control device 5 to a distribution line 8 in the form of an annular chamber. As many suction valves 9a are connected to this distribution line 8 as each working cylinder 10 of the reciprocating piston internal combustion engine has lubricant nozzle 23. 2, eight lubrication points 23 are provided in this exemplary embodiment. Each suction valve 9a includes a cylinder 20, which is part of a piston-cylinder unit 9, which delivers the lubricant sucked in at high pressure to the associated lubrication point 23. The piston of this unit is designated 21 and is under the load of a compression spring 9b which presses the piston 21 into the starting position for the delivery stroke. A pressure valve 9c is connected to each cylinder 20 and leads to the associated lubrication point 23 in the cylinder 10 via a line 22. A check valve 11 is arranged in each line 22 near the connection to the lubrication point 23. All eight pistons 21 of the piston-cylinder units 9 of a cylinder 10 are supported on a common plate 24, which is connected to a common drive piston 13 via a piston rod. The piston 13 slides in a cylinder 25 and is moved by a compression spring 13a - and supported by the springs 9b - against a stop 15 when the piston 13 executes its return stroke. To drive the piston 13, a pressure medium supply line 26 is connected to the cylinder 25, which has a control valve 14 which controls the pressure medium supply under the piston 13 during its delivery stroke. The stop 15 goes down into a thread, at the lower end of which there is a hexagon 15a, which is used to adjust the height of the stop 15 by hand. For this purpose, the thread of the stop is guided in a threaded sleeve 15c. Below the hexagon 15a, the stop 15 has a drum 15b with longitudinal grooves. The drum 15b is connected to a stepping magnet 16 in a torsionally rigid but axially loose connection, specifically via a corresponding coupling 16a. With the help of the step magnet 16, the height of the stop 15 is normally set. A proximity switch 17 is provided in the peripheral region of the drum 15b and monitors the respective position of the stop 15 with the aid of the longitudinal grooves of the drum 15b. On the plate 24, a rod 12a is attached in the center thereof, which extends upwards between the piston-cylinder units 9 and cooperates with a proximity switch 12, which controls the delivery stroke of the common drive piston 13 and the pistons 21 and via a signal line 12 reports corresponding signals to the monitoring unit already mentioned, not shown. The parts of the lubrication device described so far and framed by a dashed line are available per cylinder of the reciprocating piston internal combustion engine. In order to control the quantity of lubricating oil to be supplied in cycles via the lubrication points 23 of the cylinder running surface, a control device 18 is provided which is constructed electronically and which is common to all cylinders. Operating data of the reciprocating piston internal combustion engine are input to the control device 18, specifically crank angle, rotational speed, load on the reciprocating piston internal combustion engine and temperature on the cylinders 10 etc. The entered data are evaluated in the control device 18 and this then gives corresponding control signals via signal lines 18a and 18b for influencing the cycles amount of lubricating oil to be introduced. As the pressure medium driving the common drive piston 13, e.g. the bearing oil used in the reciprocating internal combustion engine. The quantity of lubricating oil is conveyed in such a way that during the working stroke of the piston 10 ′ in the cylinder 10, the lubricating oil at the lubrication points 23 reaches the cylinder when the uppermost piston ring 10 ″ comes into the area of the lubrication points 23. The lubrication points 23 are arranged at a point on the cylinder 10 at which the piston 10 'is located before it reaches its top dead center. The electronic control device 18 is set up in such a way that it not only issues the commands for triggering the delivery strokes of the piston-cylinder systems 9 of all the cylinders 10, but also adjusts the amounts of lubricating oil, checks these amounts and reports a possible fault in the lubricating device. In this case, the amount of lubricating oil can be adjusted by hand. The control device 18 controls the functions mentioned according to a program which corresponds to the respective operation of the reciprocating piston internal combustion engine, i.e. whether this machine drives a ship whose propeller has fixed or adjustable blades or whether the machine drives an electric generator. The control device also enables increased lubrication in a cylinder whose temperature is starting to rise dangerously. The control device 18 can also be manually entered that an increased amount of lubricating oil is to be used in a cylinder during its running-in phase.
