  • 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.
