Definitions
- the invention relates to a valve stem guide according to the generic term of claim 1.
- a valve stem guide with forced lubrication is known from EP 0526 736 B1, at the oil is fed from a pressure lubrication system through a hole in the cylinder head becomes. This bore opens into a lubrication groove in the guide bush. A part the oil is drained through the gap between the valve stem and guide bushing goes directly into a valve cover and from there via openings for the Push rods into the crankcase. On the other hand, oil gets into the valve migrates into an annular groove and from there along a longitudinal groove of the guide bush with parts of exhaust gas also in the valve cover.
- the invention is based on the task of lubrication design that no hole in the cylinder head is required for the oil supply, and that the contamination of the lubricating oil by exhaust gas components is avoided.
- the oil is supplied via rocker arm and bore in the valve stem without any additional Bore in the cylinder head.
- the separation of leak oil and exhaust gas discharge prevented the oil pollution.
- valve stem guide An embodiment of a valve stem guide according to the invention is based on a Drawing shown.
- a cylinder head 1 with four valves has two exhaust valves 2a, 2b. Since the Exhaust valves 2a, 2b are identical, the invention will only be explained on valve 2a.
- the Oil through a transverse bore 7 and an annular lubricating groove 8 in the gap between Valve stem 4 and guide bushing 5. That supplied by the pressure circulation lubrication Oil now gives way due to the pressure and the linear movement of the valve stem 4 starting from the lubrication groove 8 on both sides.
- the oil which is in the direction the valve spring 9 flows, goes directly into the valve cover 10 and can through openings 11 flow back into the crankcase for the push rods.
- the oil which flows in the direction of the outlet channel 3 is in a relief groove 12 collected and returned from there through bore 13 into the valve cover 10.
- the oil supply to the bore 6 in the valve stem 4 takes place via a central bore 16 in a rocker arm shaft 17. Starting from this central bore 16, the oil passes over Rocker arm bores 18, 19 to a spherically mounted rocker arm 20 which seals is pressed onto a bridge 21, where the oil is distributed through distribution bores 21a, 21b the holes in the valve stem is fed.
- the invention is of course not on cylinder heads with two exhaust valves 2a, 2b limited.
- the rocker arm foot is seated 20 directly on the valve stem 4.
