Abstract

An elongated housing 10 has a positioning rod 13 located therein, slidable with respect to the housing. A guide rod 14 slides parallel to the positioning rod. The guide rod and the positioning rod are coupled together by end elements 38, 39. The housing 10 is formed with recesses or bores 11, 12 for the positioning rods 13, 14 and additionally is formed with bores to transfer energy at power level for subsequent positioning or operating units, as well as to permit transfer of control signals. The positioning rod can be operated by fluid pressure by coupling a piston, slidable within its operating space and forming a cylinder, or by an electrical rack-and-pinion or worm screw drive. The unit is compact and closed towards the outside, suitable for modular association with similar or other units, and devoid of external flexible hoses or cables interfering with access thereto.
