Valve control unit

Abstract

Existing valve control devices are set up in housings that feature also the complete yoke in addition to the valve spools. In order to reduce the assembly effort required as well as the play of the valve domes on the inside of the spool, yoke arrangements are mounted externally on the housing. Such valve control devices are suitable for antilock braking systems, anti-slip control systems, electronic brake servos, and electronic stabilizing programs in motor vehicles.

What is claimed is:  
     
         1 . Valve control device for controlling a valve unit with 
 a housing ( 8 ) which comprises the circuit carrier,    at least one spool ( 5 ) which is located in the same housing ( 8 ) and is used to operate the valve domes ( 11 ) of the valve unit ( 12 ), and    at least one yoke arrangement ( 6 ,  15 ,  16 ) located above the spool ( 5 ),    wherein the yoke arrangement ( 6 ,  15 ,  16 ) is mounted externally on the housing.    
     
     
         2 . Valve control device according to patent    claim 1    wherein the yoke arrangement ( 6 ,  15 ,  16 ) is located movably in relation to the embedded spool ( 5 ).  
     
     
         3 . Valve control device according to Patent    claim 2   , with 
 spool ( 5 ) comprising a spool body ( 3 ), and where the spool body features a spool body aperture for entering the valve dome, and    the yoke arrangement featuring a yoke aperture for accepting the valve dome,    wherein the diameter (d s ) of the spool body aperture is larger than the diameter (d j ) of the yoke aperture.    
     
     
         4 . Valve control device according to patent    claim 1    wherein a bell-shaped yoke arrangement ( 15 ) is located above the spool ( 5 ).  
     
     
         5 . Valve control device according to patent    claim 1    wherein a U-shaped yoke arrangement ( 16 ) is located above the spool ( 5 ).  
     
     
         6 . Valve control device according to patent    claim 1    wherein a C-shaped yoke arrangement ( 6 ) is located to one side of the spool ( 5 ).
