Patent ID: 7368826

Claim:
Electro-hydraulic unit ( 10 ) in particular for an anti-locking device for wheels of an automotive vehicle, said electro-hydraulic unit being of the type comprising two separate parts: an electronic control ( 13 ) within which is located particularly an electronic card ( 14 ), winding ( 17 ) as well as an electric motor ( 15 ) provided with a rotor and a stator, said motor being adapted to drive a pump, and a hydraulic unit ( 11 ), comprising the pump and a plurality of valves ( 12 ), the whole electronically directed by the control ( 13 ), said electro-hydraulic unit comprising moreover: a ferromagnetic circuit ( 22 ) common at least partially to the stator and to the winding ( 17 ), said unit being characterized in that the ferrocircuit ( 22 ) is a separate element from the hydraulic unit and has at its periphery an annular flange ( 23 ) housing the winding ( 17 ), said annular flange ensuring simultaneously a function of mechanical holding of the winding ( 17 ) and a function of magnetic conduction for these winding.
