Claim 0:
1. A valve assembly for a vehicle brake apparatus, comprising:
a solenoid valve;
a pump housing having a bore configured to accommodate at least a portion of the solenoid valve;
a coil configured to selectively generate a magnetic force to move the solenoid valve;
a circuit board configured to selectively output an electric current;
a circuit board housing configured to accommodate the circuit board;
a bobbin at least partially disposed within and in electrical contact with the coil;
a pin coupled to and in electrical contact with a top portion of the bobbin;
a protrusion extending upwardly from the top portion of the bobbin and through the circuit board housing and configured to be elastically deformed when pressed toward the circuit board housing, wherein the pin and the protrusion are respectively disposed at radially opposite portions of the top portion of the bobbin;
a coil case at least partially covering an outer surface of the coil; and
an elastically deformable compression unit in contact with and extending between the circuit board and the pin and configured to transmit the electric current from the circuit board to the pin and compress the bobbin and the coil case toward the pump housing,
wherein the electrical current output from the circuit board is applied to the coil through the compression unit, pin, and bobbin.
