A cylinder actuator has a cylinder barrel, a piston running axially therein, a piston rod running through a first end plate and a stop for limiting motion of the plunger (made up of the piston and its piston rod) by cooperation with an abutment on the plunger. The maximum extent to which the piston rod may be moved out of the barrel is adjustable. The stop mounted within the cylinder is in the form of a radial projection mounted on a stop rod and able to be adjusted in the axial direction. The stop rod extends from the second cylinder and plate along a coaxial hole in the stop rod. This hole has a part of small diameter adjacent to said second end plate and a part of large diameter remote therefrom, said large and small diameters joining at a radial shoulder in said stop rod, said shoulder forming said abutment. The radial projection is located in the hole part with the large diameter. |
