Patent ID: 6899123

Claim:
A method for producing a valve assembly ( 1 ) for a hydraulic vehicle brake system with traction control, the system having at least one electromagnetically actuatable valve ( 6 ; 6 a ; 6 b ; 6 c ), which receives valve components in a valve housing ( 12 ; 12 a ; 12 b ; 12 c ) and is retained by nonpositive and/or positive engagement by fastening means in a receiving bore ( 4 ; 4 a ; 4 b ; 4 c ) of a valve block ( 2 ; 2 a ; 2 b ; 2 c ) that at least in the region of this receiving bore ( 4 ; 4 a ; 4 b ; 4 c ) comprises thermoplastic, and the fastening means have at least one retracted, plastic-filled region ( 46 , 48 , 50 ; 46 a , 48 a , 50 a ; 46 b , 48 b , 50 b ; 46 c , 48 c , 50 c ), on the radially outer circumference ( 80 c ) of the valve housing ( 12 c ) or of a valve holder ( 30 ; 30 a ; 30 b ) retaining the valve housing ( 12 ; 12 a ; 12 b ) in the receiving bore ( 4 ; 4 a ; 4 b ), the method comprising heating the valve ( 6 ; 6 a ; 6 b ; 6 c ) or the valve holder ( 30 ; 30 a ; 30 b ) before its insertion into the valve block ( 2 ; 2 a ; 2 b ; 2 c ); inserting the heated valve ( 6 ; 6 a ; 6 b ; 6 c ) or valve holder ( 30 ; 30 a ; 30 b ) into the receiving bore ( 4 ; 4 a ; 4 b ; 4 c ); permitting plastic of the valve block ( 2 ; 2 a ; 2 b ; 2 c ) heated and melted by the heated valve ( 6 ; 6 a ; 6 b ; 6 c ) or the heated valve holder ( 30 ; 30 a ; 30 b ) to flow into the at least one retracted region ( 46 , 48 , 50 ; 46 a , 48 a , 50 a ; 46 b , 48 b , 50 b ; 46 c , 48 c , 50 c ) of the valve housing ( 12 ) or of the valve holder ( 30 ; 30 a ; 30 b ); and permitting cooling and setting of the thermally deformed plastic to thereby attain a positive-engagement connection embodied between the valve block ( 2 ; 2 a ; 2 b ; 2 c ) and the valve housing ( 12 c ) or the valve holder ( 30 ; 30 a ; 30 b ).
