Abstract
Official abstract text for this publication.
A tappet ( 1 ) for a reciprocating-piston combustion engine, which is situated within a tappet guide of a component fixedly attached to the engine, and having a bearing-mounted roller ( 8 ) guided on a pin ( 3 ), which roller is in active contact with a cam or an eccentric of a shaft of the reciprocating-piston combustion engine. The casing surface of the cam or eccentric is implemented axially parallel to the shaft and the roller ( 8 ) is guided so as to oscillate on the pin ( 3 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A tappet for a reciprocating-piston combustion engine, situated within a tappet guide of a component fixedly attached to the engine, the tappet comprising a bearing-mounted roller guided on a pin, roller bodies, and an inner ring located within the roller that are connected to one another at a fixed angle, wherein the inner ring has a concave inner surface which is in contact with a convex outer surface of an intermediate ring, and wherein said roller is in active contact with a cam or an eccentric of a shaft of the reciprocating-piston combustion engine, a casing surface of the cam or eccentric is implemented axially parallel to the shaft, and the roller is guided so as to oscillate on the pin, and the roller bodies and an inner ring located within the roller are connected to one another at a fixed angle. 2. The tappet according to claim 1 , wherein the inner ring is guided so as to be oscillating relative to the pin. 3. The tappet according to claim 1 , wherein the intermediate ring has a longitudinal slit situated outside of a loading zone of the inner ring in an operating state. 4. The tappet according to claim 1 , wherein the intermediate ring is situated on the pin by an interference fit. 5. The tappet according to claim 1 , wherein the pin is caulked at its ends to the tappet. 6. The tappet according to claim 1 , wherein the roller forms an outer ring of a roller bearing.
