Claim 0:
1. A device for generating pressure pulses, the device comprising:
a valve member disposed in a fluid passageway, the fluid passageway including a restriction, the valve member movable by an actuator relative to the restriction to generate a pressure pulse in a fluid in the fluid passageway based on varying a relative position between the valve member and the restriction and creating a differential pressure across the fluid passageway, the differential pressure applying a first force on the valve member; and
a piston member in hydraulic communication with the differential pressure, the differential pressure applying a second force on the piston member, the piston member having a locomotive connection to the valve member, wherein the actuator includes an electric motor and is configured to apply a third force on the valve member to generate the pressure pulse.
