A method is for closing a solenoid valve in which the solenoid valve is charged with a first current value that results in a first closing of the solenoid valve, and the solenoid valve is subsequently charged with a second current value that results in a renewed partial opening of the solenoid valve, and the solenoid valve is subsequently charged with a third current value that results in a second closing of the solenoid valve, the third current value being selected such that the second closing takes place with a higher closing speed of the solenoid valve than does the first closing.

Method for reliably closing a solenoid valve

A hydraulic part of a magnet valve is received in a bore of a valve block. The hydraulic part is secured to the valve block with a calked heel of a securing bush that is slipped onto a guide sleeve of the hydraulic part. The securing bush rests on an annular shoulder of the guide sleeve and engages a jacket wall of the guide sleeve with a press fit, and one edge of the securing bush is adapted to a rounded-out throat between the jacket wall and an end wall of the annular shoulder by means of plastic deformation. A valve sleeve engages a portion of the bore of the valve block with a press fit. The calked heel, the plastically deformed edge of the securing bush, and the press fit of the valve bush seals that seal off against fluid are achieved without using additional rubber-elastic sealing means.
