- the caulking 21a or 21b the magnet assembly 1 is thus forced into the receptacle 3, whereby the valve sleeve 4 is pressed into the hydraulic block 102 by means of the housing part 18 and the stop 19.
- 2 shows two alternatives: on the left half a rolling caulking 21a and on the right half a force-reducing Taumelverstemmung 21b.
- the hydraulic block 102 has at least one first fluid connection 22, which is in fluid communication with the outflow openings 15, so that Hydraulic medium accordingly through the discharge opening in the or
- the hydraulic block 102 has a further fluid connection 23 in the extension of the valve sleeves 4 and 8, which is directly in fluid communication with the flow opening 11 in connection.
- a fluid in the direction of the arrow 24 can then pass from the fluid connection 23, through the throughflow opening 11, into the outflow openings 15, to the fluid connection 22.
- FIG. 2 shows a semitransparent representation of an embodiment of a hydraulic unit 100 according to the invention from two viewing directions.
- the hydraulic unit 100 consists of the component group valve device 101, hydraulic block 102, control unit 103 and pump group 104.
- the hydraulic block 102 is here shown transparent and illustrates that the valve devices
- valve devices 101 lie. It is also clear that all valve devices 101 are integrated into the hydraulic block 101. Furthermore, the right-hand illustration shows four wheel connections 25.
