Internal combustion engine comprising at least one camshaft

Abstract

An internal combustion engine, having at least one camshaft, which is mounted in the radial direction via at least one bearing block supplied with bearing fluid, wherein in the region of the bearing block, two sealing rings are provided, which are axially spaced apart from each other and which seal an annular chamber supplied with bearing fluid and located between the camshaft and the associated bearing block at least partially in the axial direction.

1 . An internal combustion engine, comprising;
 at least one camshaft, which is mounted in the radial direction via at least one bearing block supplied with bearing fluid, wherein in the region of the bearing, two sealing rings are provided, which are axially spaced apart from each other and which seal an annular chamber supplied with bearing fluid and located between the camshaft and the associated bearing block at least partially in the axial direction.   
     
     
         2 . The internal combustion engine according to  claim 1 , wherein at least one bearing fluid feed channel extending in the bearing block opens out in the annular chamber. 
     
     
         3 . The internal combustion engine according to  claim 1 , wherein at least one sealing ring is formed as the sealing ring, which is at least one of closed and open in the circumferential direction. 
     
     
         4 . The internal combustion engine according to  claim 1 , wherein at least one sealing ring is formed from at least one of a plastic and a metal. 
     
     
         5 . The internal combustion engine according to  claim 1 , wherein at least one sealing ring has at least one of a friction reducing coating and a wear reducing coating. 
     
     
         6 . The internal combustion engine according to  claim 1 , wherein at least one sealing ring is formed in such a manner that a defined leakage flow is possible. 
     
     
         7 . The internal combustion engine according to  claim 1 , wherein a groove is provided on at least one of the camshaft and the bearing block, with which the associated sealing ring engages. 
     
     
         8 . The internal combustion engine according to  claim 1 , wherein at least one sealing ring is joined to at least one of the camshaft and the bearing block. 
     
     
         9 . The internal combustion engine according to  claim 1 , wherein at least one sealing ring is formed at the same time as the axial bearing. 
     
     
         10 . The internal combustion engine according to  claim 2 , wherein at least one sealing ring is formed as the sealing ring, which is at least one of closed and open in the circumferential direction. 
     
     
         11 . The internal combustion engine according to  claim 4 , wherein at least one sealing ring is formed from at least one of a polytetrafluoroethylene (PTFE) plastic and a cast metal material. 
     
     
         12 . The internal combustion engine according to  claim 2 , wherein at least one sealing ring has at least one of a friction reducing coating and a wear reducing coating. 
     
     
         13 . The internal combustion engine according to  claim 2 , wherein at least one sealing ring is formed in such a manner that a defined leakage flow is possible. 
     
     
         14 . The internal combustion engine according to  claim 2 , wherein a groove is provided on at least one of the camshaft and the bearing block, with which the associated sealing ring engages. 
     
     
         15 . The internal combustion engine according to  claim 2 , wherein at least one sealing ring is thermally joined on at least one of the camshaft and the bearing block. 
     
     
         16 . The internal combustion engine according to  claim 2 , wherein at least one sealing ring is formed at the same time as the axial bearing.
