Definitions
- the invention relates to a ⁇ labstreifring for a piston of an internal combustion engine consisting of at least one blade, each with a shock and from a meandering distance spring with a shock, wherein the blade and the distance spring are in contact.
- Object of the present invention is therefore to avoid this disadvantage of the prior art, that is, to design the oil control ring such that a snagging of the ends of the blade and the distance spring is avoided.
- This object is achieved in that the impact of at least one blade with the radius of the at least one blade includes an acute angle. This causes the ends of the louver joint does not come into contact with the ends of the spring shock over its entire width, so that in this case slide the louver abutment over the spring butt ends, and a snagging of the spring butt ends is avoided in the lamella abutment ends.
- Bestnessistskopiel 1 shows a three-piece ⁇ labstreifring in section with two blades and a distance spring
- Fig. 4 is a side view of the oil control ring under load
- Fig. 5 is a plan view of a blade.
- Fig. 1 shows a ⁇ labstreifring 1, which consists of two blades 2 and 3 and a distance spring 4, and which in a two flanks 7, 8 and a bottom surface 12 existing annular groove 9 of a piston 13 for an internal combustion engine stores.
- the object of the oil scraper ring 1 is to strip off superfluous oil adhering to the running surface 5 of a cylinder liner 6 shown in detail in FIG.
- the distance spring 4 for this purpose on supporting elements 10 and 11, against which the slats 2, 3 and over which the distance spring 4, the slats 2, 3 presses on the running surface 5 of the cylinder liner 6.
- FIG. 2 and 3 show the distance spring 4, wherein in Fig. 2 is a section through the spacer spring 4 along the line AA in Fig. 3 is shown.
- the distance spring 4 is meander-shaped, and that arranged at the crests 14 of the meandering arches 15 supporting elements 10 and 11 extensions of the legs 16 of the meandering arches 15 and 15 abut only loosely at the apexes 14 of the meandering bows.
- Fig. 3 shows that the distance spring 4 has a shock 17, which can move in the direction of the arrow 18 depending on the load during engine operation.
- Fig. 4 is a side view of the oil control ring 1 with the spacer spring. 4 and with the blades 2, 3 with the joints 19, 19 'shows.
- Fig. 4 is a side view of the oil control ring 1 with the spacer spring. 4 and with the blades 2, 3 with the joints 19, 19 'shows.
- the blade 2 relative to the distance spring 4 shifts so far that the shock 17 of the distance spring 4 and the joint 19 of the blade 2 come to lie opposite each other, and that due to a deformation of the annular groove 9 below the load of the combustion gases and the mass forces acting on the piston 13, a contact between the shock 17 of the distance spring 4 and the impact 19 of the lamella 2 results.
- the lamellae 2, 3 of the oil control ring 1 each have a to the radius 20 of the lamella 2, 3 oblique shock 19, which includes an acute angle ⁇ with the radius 20 of the lamella 2, 3 as shown in Fig. 5.
- This has the effect that the ends of the lamellar joint 19 do not come into contact with the ends of the spring joint 17 over their entire width, so that in this case the lamella abutments slide over the spring abutments, and snagging of the spring abutments in the lamellar abutments is avoided.
- the joints 19, 19 'of the blades 2, 3 with the radius 20 of the respective blade 2, 3 include different angles ⁇ , ie, intersect at a certain angle, whereby the stability of the oil control ring 1 is increased when the joints 19th , 19 'of the slats 2, 3 come to lie opposite each other.
- the annular groove 9 facing away from the piston bottom is provided with radially disposed oil return grooves, so that when the lower blade 3 rotates, its joint 19 'hooks into the flanks of the oil return groove. Due to the inclined position of the joint 19 ', which forms an acute angle ⁇ with the radius 20 of the lamella 3, this snagging is avoided. List of angles Angle between the impact of a lamella and the radius of the lamella oil control ring
