Abstract
A mud pulser includes a connector housing, a motor housing, a ball screw housing, a pressure compensation piston housing, and a filter housing that are tubular in shape and connected serially to form a tubular housing. A pressure compensation piston separates the tubular housing into a proximal portion and a distal portion; a motor resides in the proximal portion; a servo valve resides in the distal portion; a piston shaft is coupled to the motor and extends through the pressure compensation piston into the distal portion. The motor causes the poppet shaft to reciprocate along a longitudinal direction of the tubular housing. The filter housing contains a plurality of slots that extend into an inter cavity of the filter housing.
