Abstract: A drilling module is for radial drilling in a well and an anchoring module is for use in a well tool. The drilling module has a piston for receiving a drill for the radial drilling, and for displacing the drill in a radial direction towards a wall of the well and a cylinder for receiving and guiding the piston. Both the piston and the cylinder are guide-free and of a non-circular shape, at least in a portion, to prevent relative rotation between them. The anchoring module has an extent in the axial direction of the well. The anchoring module includes a displacement device arranged to push against a portion of the wall of the well to press the anchoring module against an opposite portion of the wall of the well. The displacement device is oblong in the axial direction of the anchoring module.

Abstract: A device for pumping paint includes a pump house adapted to receive paint from a paint source, a pump shaft for driving a pump member to rotate inside the house for pumping paint therethrough. The pump shaft is connected to an output shaft of a motor arranged outside the pump house through an intermediate shaft piece through a wall of the pump house. The motor is arranged to drive the pump shaft and the pump member. A sealing member is arranged to counteract paint leaking out of the pump housing along the pump shaft. The sealing member is arranged to seal by bearing substantially axially against substantially axial surfaces of the pump shaft around the pump shaft, in which the sealing member and/or these axial surfaces are preferably of a ceramic material.

Abstract: A paint supply system for a painting robot, the system includes a paint spraying device mounted on a tool holder at the outer end of a robot arm and having an adapter unit for mounting on the robot arm close to or in direct contact with the paint spraying device, first and second supply lines for supplying first and second painting fluids to the adapter, and a third supply line for supplying a cleansing fluid to the adapter. The adapter includes a first inlet duct connected to the first supply line, a second inlet duct connected to the second supply line, a third inlet duct connected to the third supply line, an outlet duct connected to the paint spraying device, first valve means for connecting the first inlet duct to the outlet duct, second valve means for connecting the second inlet duct to the outlet duct, and third valve means for connecting the third inlet duct to the outlet duct.
