Claim 12:
13. An electro-hydraulic pedal assembly comprising:
a solenoid including an armature surrounded by a conductive winding, such that energizing the conductive winding causes the armature to travel in a first direction;
a foot pedal including a piston that is mechanically coupled to the solenoid armature, such that depression of the foot pedal causes the armature to travel in the first direction; and
a hydraulic valve including a spool that is responsive to the position of the armature and is contained within a valve body having a pressure port, a work port, and a tank port, such that the solenoid and the foot pedal are first and second valve operators that independently cause the spool to move from a first position in which the work port is closed to the pressure port to a second position in which the work port is open to the pressure port.
