Definitions

  • the notable protrusion can also constitute a risk in the case of accidental collisions with blunt objects, such as stones.
  • said coupling outline 24 has a hexagonal cross section.
  • said connecting means 26 comprises a connector.
  • Said shape coupling specifically permits mechanical coupling between said control surface 8 and said control counter-surface 20.
  • a bleeding device 1 as described involves the use of a bleeding tool 9 exclusively constructed for operation of said bleeding device 1; in this way the possibility of any tampering using common keys is avoided, increasing the safety of the brake plant and thus also of the motor vehicle's user.
  • said bleeding device 101 comprises at least one sealing surface 110 distinct from said control surface 108 suitable for hydraulic coupling with at least one portion of said bleeding tool 109.
  • said distinct sealing surface 110 is inside said bleeding device 101.
  • said site 125 is aligned with said collection channel 118.
  • the number 201 indicates a further embodiment of said bleeding device 101 whose functioning is essentially analogous to said bleeding device 101, comprising a first end 205, a second end 206 and an intermediate portion 207, all analogous to said first end 105, second end 106 and intermediate portion 107.
