Gasket

Abstract

The invention relates to a gasket ( 1 ), particularly for a fuel high-pressure pump, comprising a first cutout ( 2 ) for a cylinder head, a second cutout ( 3 ) for a high-pressure channel, and a third cutout ( 4 ) for an induction channel. A first ( 5 ) and second sealing bead ( 6 ) are respectively formed around the cutouts for the high-pressure channel as well as around the cutout for the induction channel. The gasket ( 1 ) comprises a wider third sealing bead ( 7 ) that is formed so that it encircles the other sealing beads.

1 . A gasket comprising: 
 a first cutout for a cylinder head,    a second cutout for a high-pressure channel,    a third cutout for an induction channel,    a first sealing bead around the second cutout for the high-pressure channel,    a second sealing bead around the third cutout for the induction channel,    a third sealing bead which encircles the first and second sealing bead, and    a discharge opening being introduced within the surface encircled by the sealing bead.    
     
     
         2 . A gasket according to  claim 1 , wherein the first sealing bead, which is arranged around the high-pressure channel, has a coaxial profiling.  
     
     
         3 . A gasket according to  claim 2 , wherein the coaxial profiling has a wave-shaped and/or sawtooth-shaped profile.  
     
     
         4 . A gasket according to  claim 1 , wherein the seal has positioning tabs for precise positioning of the seal between the components to be sealed or on one of the components to be sealed.  
     
     
         5 . A gasket according to  claim 1 , wherein the gasket consists of a spring steel or of a metal which can preferably be worked cold.  
     
     
         6 . A gasket according to  claim 1 , wherein the seal is coated at least partially with an elastomer or another suitable plastic, or with metal.  
     
     
         7 . A gasket comprising: 
 a first opening for a cylinder head,    a second opening for a high-pressure channel,    a third opening for an induction channel,    a first sealing bead around the second opening,    a second sealing bead around the third opening,    a third sealing bead which encircles the first and second sealing bead, and    a discharge opening being introduced within the surface encircled by the third sealing bead.    
     
     
         8 . A gasket according to  claim 7 , wherein the first sealing bead, which is arranged around the high-pressure channel, has a coaxial profiling.  
     
     
         9 . A gasket according to  claim 8 , wherein the coaxial profiling has a wave-shaped and/or sawtooth-shaped profile.  
     
     
         10 . A gasket according to  claim 7 , wherein the seal has positioning tabs for precise positioning of the seal between the components to be sealed or on one of the components to be sealed.  
     
     
         11 . A gasket according to  claim 7 , wherein the gasket consists of a spring steel or of a metal which can preferably be worked cold.  
     
     
         12 . A gasket according to  claim 7 , wherein the seal is coated at least partially with an elastomer or another suitable plastic, or with metal.  
     
     
         13 . A gasket comprising: 
 a first opening for a cylinder head,    a second opening for a high-pressure channel,    a third opening for an induction channel,    a first sealing bead around the second opening having a coaxial profiling,    a second sealing bead around the third opening,    a third sealing bead which encircles the first and second sealing bead, and    a discharge opening being introduced within the surface encircled by the third sealing bead.    
     
     
         14 . A gasket according to  claim 13 , wherein the coaxial profiling has a wave-shaped and/or sawtooth-shaped profile.  
     
     
         15 . A gasket according to  claim 13 , wherein the seal has positioning tabs for precise positioning of the seal between the components to be sealed or on one of the components to be sealed.  
     
     
         16 . A gasket according to  claim 13 , wherein the gasket consists of a spring steel or of a metal which can preferably be worked cold.  
     
     
         17 . A gasket according to  claim 13 , wherein the seal is coated at least partially with an elastomer or another suitable plastic, or with metal.
