Abstract
A compensator device includes a hydraulic cylinder with a first end, a second end and an inner cylinder rod extending axially from the second end; and a piston rod with a piston movable axially within the cylinder. The inner cylinder rod has an end with a blocking diameter. The piston rod is generally hollow and includes a cavity to receive the blocking diameter of the inner cylinder rod.
Claims15
A compensator device comprising:
- a hydraulic cylinder with a first end, a second end and an inner cylinder rod extending axially from the second end, the inner cylinder rod with an end with a blocking diameter;
- and
- a piston rod with a piston movable axially within the cylinder, the piston rod being generally hollow and with a cavity to receive the blocking diameter of the inner cylinder rod.
A method of forming a compensator device, the method comprising:
- forming a hydraulic cylinder with a first end and a second end;
- forming an inner cylinder rod with an end with a blocking area, the inner cylinder rod being formed to extend axially within the hydraulic cylinder from the second end;
- forming a piston rod and piston, the piston rod with a generally hollow interior and with a cavity to receive the blocking area of the inner cylinder rod;
- and
- connecting the piston rod and piston through the first end of the hydraulic cylinder so that it can move axially in the hydraulic cylinder.
