Soil Compaction Machine with Internal Combustion Engine and Improved Air Supply

Abstract

A hand-guided soil compacting machine, such as a vibration tamper, is provided. The compacting machine includes an internal combustion engine for driving a compacting plate and at least one guide bar for holding and/or guiding the soil compacting machine.

1 . A hand-guided soil compacting machine, comprising:
 an internal combustion engine for driving a compacting plate; and   at least one guide bar, for holding and/or guiding the soil compacting machine, including at least one flow channel through which a supply of combustion air to the internal combustion engine flows at least in sections.   
     
     
         2 . A soil compacting machine according to  claim 1 , wherein the flow channel is integrated in the guide bar. 
     
     
         3 . A soil compacting machine according to  claim 2 , wherein the guide bar is formed at least in sections from a hollow section whose cavity forms the integrated flow channel. 
     
     
         4 . A soil compacting machine according to  claim 2 , wherein at least one air-filter unit is arranged on the guide bar which is in fluid connection with the integrated flow channel. 
     
     
         5 . A soil compacting machine according to  claim 4 , wherein the fluid connection between the integrated flow channel and the air-filter unit is realized by means of a connecting flange. 
     
     
         6 . A soil compacting machine according to  claim 1 , wherein the guide bar is fastened in a vibration-dampened manner to the soil compacting machine. 
     
     
         7 . A soil compacting machine according to  claim 6 , wherein the vibration-dampened fastening of the guide bar comprises at least one elastic damping element which allows conducting the combustion air. 
     
     
         8 . A soil compacting machine according to  claim 7 , wherein the damping element is arranged as a rubber buffer with at least one bore hole for conducting the combustion air. 
     
     
         9 . A soil compacting machine according to  claim 8 , wherein the bore is an axial bore hole. 
     
     
         10 . A soil compacting machine according to  claim 8 , wherein the fluid connection between the integrated flow channel and the bore hole in the rubber buffer is realized by means of a connecting flange. 
     
     
         11 . A soil compacting machine according to  claim 1 , wherein a fuel tank is arranged on the guide bar. 
     
     
         12 . A soil compacting machine according to  claim 11 , wherein the air-filter unit and the fuel tank are arranged in a common housing.
