MOTORDRIVEN UTRUSTNING FOR VENTILMANOVRERING

摘要

A portable motor-driven apparatus for manipulating valves of the kind which have screwthreaded valve spindles extending in wells or like conduits. The apparatus comprises an internal combustion motor (1) which is firmly mounted on a carrier frame. The motor drives a rod (15) which carries on one end thereof a tool (15) for turning the valve spindle. For the purpose of preventing relative rotation between the motor unit and respective wells or like conduits, the apparatus includes means (17) for temporarily connecting the motor unit with the well or like conduit. This means suitably has the form of a torsionally rigid tube (17) which surrounds the drive rod (15) and which is provided with a catch device (18) which fits the well opening.
