  • Patent number: 8424978
    Abstract: 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.
    Type: Grant

  • Publication number: 20040251738
    Abstract: A magnet valve, including a pole core, an armature, a restoring element disposed between the pole core and the armature to restore the armature to its outset position a stop face on the pole core oriented toward the armature having at least one rib extending all the way around in the circumferential direction and protruding toward the armature, and/or a stop face of the armature oriented toward the pole core and having at least one rib extending all the way around in the circumferential direction and protruding toward the pole core.

  • Patent number: 6789779
    Abstract: 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.

  • Publication number: 20040089832
    Abstract: A hydraulic part 13 of a magnet valve 10 is received in a bore 14 of a valve block 11. The securing of the hydraulic part 13 to the valve block 11 is attained with a calked heel 53 of a securing bush 43 that is slipped onto a guide sleeve 21 of the hydraulic part 13. The securing bush 43 resting on an annular shoulder 27 of the guide sleeve 21 engages a jacket wall 28 of the guide sleeve 21 with a press fit. In addition, one edge of the securing bush 43 is adapted to a rounded-out throat between the jacket wall 28 and an end wall 29 of the annular shoulder 27 by means of plastic deformation. In addition, a valve sleeve 33 engages a portion 47 of the bore 14 of the valve block 11 with a press fit.

  • Patent number: 6322049
    Abstract: A tubular valve housing includes a guide body for pressure fluid that is disposed between a valve body having a hollow-conical valve seat and a chamber of the valve housing, in which actuating means of the valve are received in the chamber. The guide body is penetrated by a closing body of the valve which divides the chamber from an annular conduit. The annular conduit carries the pressure fluid and communicates with the valve seat and has circumferential outlet openings of the valve housing. The guide body is braced on the valve body, with a face end contacting the valve body, and has guide conduits, fitting over an outline of the valve seat, which on the outlet side discharge into the annular conduit. The face end of the closing body, which cooperates with the valve seat, is a spherical portion that makes a transition with sharp edges to the cylindrical shaft of the closing body.
