Abstract:
A piston/cylinder assembly, comprisinga cylinder;an elongated piston received in the cylinder for axial movement through a piston stroke, the piston having a seal adjacent each end and dividing the cylinder into two working chambers, one adjacent each end of the piston,a first connecting member affixed to the cylinder and adapted to connect the cylinder to one of two elements that are movable relative to each other;at least one second connecting member operatively coupled to the piston,each second connecting member extending through an opening in the cylinder located between the two working chambers and adapted to connect the piston to the other of the two elements,the opening having a length axially of the cylinder that is not less than the length of the piston stroke,the seals being located such that they are spaced apart from the opening in the cylinder in all positions of the piston during the piston stroke, andthe opening having portions that are offset in the circumferential direction from each other and form a guideway frame for the second connecting member on the piston so as to impart rotation of the piston in the circumferential direction.
