Compensation reservoir for a cooling circuit of an internal combustion engine

Abstract

A compensating tank for a cooling circuit of an internal combustion engine has at least one inflow connection and one outflow connection, both of which are connected with the cooling circuit, a chamber system formed in the tank to receive the coolant, such that the individual chambers are at least partially interconnected via openings, and a coolant pipe connected with the inflow connection discharging into one of the chambers in which an impact element is provided for the inflowing coolant. The impact element is configured as a curved guiding wall along which the inflowing coolant is specifically guided. This inhibits, among other things, foaming of the coolant flowing into the compensating tank.

       17 . The compensating tank as claimed in  claim 9 , wherein the guiding wall is arranged in a rearmost chamber row relative to the at least one outflow connection.  
   
   
       18 . The compensating tank as claimed in  claim 10 , wherein the guiding wall is arranged in a rearmost chamber row relative to the at least one outflow connection.  
   
   
       19 . The compensating tank as claimed in  claim 11 , wherein the guiding wall is arranged in a rearmost chamber row relative to the at least one outflow connection.  
   
   
       20 . The compensating tank as claimed in  claim 11 , wherein the lower shell is provided with a chamber system such that the chambers are interconnected via openings provided in transverse walls and longitudinal walls.  
   
   
       21 . The compensating tank as claimed in  claim 12 , wherein the lower shell is provided with a chamber system such that the chambers are interconnected via openings provided in transverse walls and longitudinal walls.  
   
   
       22 . The compensating tank as claimed in  claim 9 , wherein the coolant pipe is one of two coolant pipes that discharge into the chamber system, such that a first of the coolant pipes is connected with a radiator and the second of the coolant pipes is connected with a water jacket of a cylinder head of the internal combustion engine.  
   
   
       23 . The compensating tank as claimed in  claim 10 , wherein the coolant pipe is one of two coolant pipes that discharge into the chamber system, such that a first of the coolant pipes is connected with a radiator and the second of the coolant pipes is connected with a water jacket of a cylinder head of the internal combustion engine.
