Compressor Unit

Abstract

A compressor unit has a motor and a reciprocating-piston compressor which is driven via a slider-crank drive. The slider-crank drive includes a crank wheel and a connecting rod, which is connected to the crank wheel and a piston. The piston stroke can be adjusted by a threaded connection that allows an exact spacing between the crank drive and the piston to be set.

1 . A compressor unit, comprising:
 at least one motor;   a reciprocating piston compressor with a piston having a given piston stroke;   a slider crank mechanism connected for driving said reciprocating piston compressor, said slider crank mechanism including a crank wheel, a connecting rod connected between said crank wheel and said piston, and a threaded connection for adjusting the piston stroke within said slider crank mechanism.   
   
   
       2 . The compressor unit according to  claim 1 , wherein said threaded connection is disposed to enable a length adjustment of said connecting rod. 
   
   
       3 . The compressor unit according to  claim 1 , configured in a portable compressor unit. 
   
   
       4 . The compressor unit according to  claim 1 , configured in a mobile and transportable appliance. 
   
   
       5 . The compressor unit according to  claim 1 , which comprises an antitwist device for locking said threaded connection. 
   
   
       6 . The compressor unit according to  claim 5 , wherein said antitwist device is a headless screw engaging into a thread of the threaded connection and having a rear tool catch. 
   
   
       7 . The compressor unit according to  claim 1 , wherein said threaded connection is a fine thread. 
   
   
       8 . The compressor unit according to  claim 1 , which comprises a gear unit connected between said motor and said piston compressor, said gear unit including said slider crank mechanism and at least one gearwheel stage. 
   
   
       9 . The compressor system for sealing and inflating inflatable articles, comprising:
 a compressor unit according to  claim 1 ;   a container for an automatic sealing means for introduction into and sealing the inflatable article;   a valve and distributor unit for the sealing means and compressed gas, and   a valve connecting said distributor unit with said compressor unit; and   an inlet line connecting said valve and distributor unit to said container for the sealing means and an outlet line for connecting said valve and distributor unit to an inflatable article; and   wherein a maximum pressure of said compressor unit is set to approximately 6 to 8 bars by setting said threaded connection.   
   
   
       10 . The compressor system according to  claim 9 , wherein the maximum pressure is set to a value of 7 bar. 
   
   
       11 . The compressor system according to  claim 9 , wherein the inflatable article is a motor vehicle tire.
