[0010]
  • With the entire control region of the control valve being within a rotational angle of the actuation member of 180° or 90°, a comfortable control and fixation of the displacement and support device becomes possible, without a need to turn the controlling hand over and over again. [0011]

The invention itself, however, both as to its construction and its mode of operation, together with additional advantages and objects thereof, will be best understood from the following detailed description of preferred embodiment, when read with reference to the accompanying drawings. [0018]
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • In the Drawings: [0019]
  • FIG. 1 shows a schematic view illustrating the use of a displacement and support device according to the present invention; [0020]
  • FIG. 2 shows a cross-sectional view of a displacement and support device according to the present invention along line II-II in FIG. 3; and [0021]
  • FIG. 3 shows a side view of a displacement and support device according to the present invention.[0022]
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • FIG. 1 shows the use of a displacement and support device with a [0023] portable power tool 1 used in underground mining and provided with a rotably and percussion driven, water-flushed, elongate drill 2. The displacement and support device is formed as power cylinder 3 that supports the power tool 1 against a floor and, simultaneously, applies to the drill 2 an acting in the operational direction of the drill 2, controlled displacement force. The power cylinder 3, which is inclined rearwardly, is manually guided and controlled by a user 5. Water is fed to the working or power cylinder 3 through a pressure hose 6, and to the drill 2 through the power tool 1.
  • The [0024] power cylinder 3, which is shown in FIGS. 2-3, is formed as a hydraulically driven, double-action, power cylinder and is provided, at one of its end, with an assembly element 7 easily securable to the power tool 1 and at another of its end, with a support leg 8. The power cylinder 8 is manually controlled by a control valve 10 which is formed as a rotary valve. The operation of the control valve 10 is controlled by a manually rotationally adjustable actuation member 9. The actuation member 9 is formed as a handle extending transverse to the axis A of the power cylinder 3 and rotable about the handle axis B. The actuation member 9 is rotationally adjustable within a rotational angle of 180°.
