Abstract
The invention relates to a ram comprising a piston rod in two parts mounted for relative rotation. A first part extends out of the cylinder, beyond each of the heads, while the second part extends out of the cylinder only beyond one head, namely the upper one, and comprises two axial shoulders directed in opposite directions, located at the two ends of this second part and each cooperating with a shoulder, fast with the first part, corresponding to the maintenance of a fixed relative axial position between the two parts, and two radial bearing surfaces located at the two ends of the second part and cooperating with two radial bearing surfaces fast with the first part, corresponding to the centering of the two parts. The present invention is particularly applied to a rotatable clam-shell bucket.
