Claim 0:
1. An electro-hydraulic modulating valve pedal assembly comprising:
a foot pedal pivotably mounted to a base;
a push rod operatively coupled to the pedal, such that rotation of the foot pedal relative to the base causes travel of the push rod in a first direction, the push rod including an armature;
a spool valve including a spool contained within a valve body having a pressure port, a work port, and a tank port, wherein the spool is operatively coupled to the push rod; and
a solenoid surrounding at least a portion of the armature for applying a magnetic force to the push rod and driving the push rod in the first direction, wherein the foot pedal and the solenoid are first and second valve operators for the spool valve and independently cause the spool to move in the first direction between a first position in which the work port is closed to the pressure port and a second position in which the work port is open to the pressure port.
