ABSTRACT:
The invention relates to a cylinder and piston unit with a cylinder tube closed at both its ends by cylinder end caps. An axially moving piston in the cylinder has a piston rod extending sealingly through at least one end cap. On the outer face of the tube there are four longitudinal means such as longitudinal ribs or round tie rods extending in the axial direction of the tube and equally spaced in the circumferential direction about the tube. Furthermore there is a mounting yoke for pivotally carrying the cylinder and piston unit and having at least two, and more especially four, generally diametrally opposite clamping jaws with trunnions on two of them. The mounting means furthermore constitutes an annular structure encircling the tube. At their ends the clamping jaws have gripping faces adapted to engage and grip the longitudinal ribs or rods on opposite sides thereof so that the tube is held firmly by clamping the jaws together.
