Patent ID: 7266883

Claim:
A method for producing a pressure pipe of a tractive solenoid for a hydraulic valve, which pressure pipe has a pole piece ( 31 ), a nonmagnetic intermediary piece ( 33 ), a tubular piece ( 35 ), and a stroke limiter ( 36 ), and has a receptacle ( 37 ) for an armature ( 38 ) that cooperates with a tappet ( 39 ), characterized in that the nonmagnetic intermediary piece ( 33 ) is thermally joined at its ends to the pole piece ( 31 ) and the tubular piece ( 35 ) in such a way that after the joining, a sliding surface ( 43 ) for the armature ( 38 ) is formed, and in that the armature ( 38 ) is introduced into the receptacle region ( 37 ) before the pole piece ( 31 ), the intermediate piece ( 33 ), and the tubular piece ( 35 ) are joined to one another.
