Abstract
A remotely controlled, hydraulically operated cutter apparatus for use within a conduit includes a control for generating a plurality of control signals for controlling the operation of a source of pressurized hydraulic fluid. Valves are provided for receiving both the pressurized fluid and the control signals and for distributing the received fluid in accordance with the received control signals. A hydraulically powered cutter motor located within the conduit and including a cutter tool receives the hydraulic fluid from the valves for driving the cutter tool. The cutter motor is supported within the conduit by supporting members. A first hydraulically actuated cylinder is included for receiving hydraulic fluid from the valves and for holding the supporting members in a fixed axial position within the conduit. Second, third and fourth hydraulically actuated cylinders are provided for adjusting the axial and radial position of the cutter motor and for rotating the cutter motor to position the cutter motor to facilitate cutting by the cutting tool.
