Patent ID: 8479773

Claim:
A hydraulic unit with a solenoid valve group, comprising: a first solenoid valve having (i) a first valve cartridge defining a longitudinal axis and (ii) a first magnet assembly defining a first axial length and being situated around the first valve cartridge, the first magnet assembly having a first exterior sidewall; a second solenoid valve having (i) a second valve cartridge and (ii) a second magnet assembly defining a second axial length and being situated around the second valve cartridge, the second magnet assembly having a second exterior sidewall; a mounting element on which the first and second solenoid valves are directly mounted and through which the first and second solenoid valves are electrically contacted; and a positioning unit situated between the first and second solenoid valves and configured to exert a force on the first and second solenoid valves so that the first magnet assembly assumes a first definite radial position with respect to the first valve cartridge and the second magnet assembly assumes a second definite radial position with respect to the second valve cartridge, wherein the positioning unit has a guide member for aligning the first and second magnet assemblies, the guide member including (i) a first projection that contacts the first exterior sidewall over a portion of the first axial length that is less than the entire first axial length, (ii) a second projection that contacts the second exterior sidewall over a portion of the second axial length that is less than the entire second axial length, and (iii) a spring element interposed between the first and second projections configured to generate the force acting on the first and second solenoid valves, and wherein the spring element is contained entirely within a space between the first exterior sidewall and the second exterior sidewall.
