Removal device for desiccant

Abstract

A removal device ( 1 ) is provided for the desiccant of the refrigerant of an air conditioner for vehicles, which is arranged in a receiver ( 4 ) connected to one manifold ( 2 ) of an integrated condenser/receiver unit ( 3 ) of the air conditioner and is fastened with one end ( 5 ) to a closure cover ( 6 ) of the receiver ( 4 ), the receiver ( 4 ) being connected via inflow and outflow openings ( 8, 9 ) in its wall ( 12 ) to the manifold ( 2 ). A receiving space for the desiccant is formed between the removal device ( 1 ) and the wall of the receiver ( 4 ) opposite the inflow and outflow openings. The removal device ( 1 ) has an impact wall ( 20 ) in the area of the inflow opening ( 8 ). The removal device ( 1 ) is formed as a rod ( 50 ) from the impact wall ( 20 ) to roughly the closure cover ( 6 ) designed as a plug ( 60 ) so that the wall of the receiver ( 4 ) lying on the side of the inflow and outflow openings is available as a boundary of the receiving space for the desiccant. The plug ( 60 ) has a recess ( 61 ), which cooperates with the wall of the receiver ( 4 ) to align the plug ( 60 ) and the removal device ( 1 ) in the receiver ( 4 ) in a prescribed position when inserted in the receiver ( 4 ).

1 . An improvement in a removal device for the desiccant of a refrigerant in an air conditioner for vehicles, the removal device arranged in a receiver connected to one manifold of a condenser of the air conditioner and is connected at one end to a closure of the receiver, the receiver being connected via inflow and outflow openings in a wall of the receiver to the manifold, with a receiving space for the desiccant being formed between the removal device and the wall of the receiver, the removal device having an impact wall in the area of the inflow opening; the improvement wherein: 
 the removal device further comprises a rod extending between the impact wall and the closure such that the wall of receiver lying on the side of the inflow and outflow openings is available as a boundary of the receiving space for the desiccant, and the closure comprises a recess which cooperates with the wall of the receiver to align the removal device in a prescribed position in the receiver.    
   
   
       2 . The improvement of  claim 1  wherein the rod had a cross-shaped cross section.  
   
   
       3 . The improvement of  claim 1  wherein the removal device further comprises a filter located at an end of the removal device opposite from the closure, and a seal engaged with the receiver between the inflow opening and the outflow opening.  
   
   
       4 . A desiccant removal device for use in an elongated receiver of an integrated condenser/receiver unit, the receiver having an open end and being connected by an inflow opening and an outflow opening to a refrigerant manifold to transfer refrigerant between the receiver and the manifold, the removal device comprising: 
 an impact wall positioned opposite from the inflow opening with the removal device inserted in the receiver;    a plug closing the open end of the receiver with the removal device inserted in the receiver, the plug including a recess that engages a portion of the receiver to properly locate the impact wall with respect to the inflow opening with the removal device located in the receiver;    a rod extending between and connecting the impact wall and the plug.    
   
   
       5 . The removal device of  claim 4  wherein the rod had a cross-shaped cross section.  
   
   
       6 . The removal device of  claim 4  further comprising a filter located at an end of the removal device opposite from the plug, and a seal engaged with the receiver between the inflow opening and the outflow opening.
