DEFINITION

Classification: 188/303

(under subclass 302) Device provided with two thrust members facing in generally the same direction and moving to-and-fro within two chambers that lie in the same plane but not in the same line, wherein said arm is connected to said thrust members so as to cause movement of one member toward an end of its chamber and simultaneously cause movement of the other member away from an end of its chamber.

(1) Note. Usually the cylinders are hydraulically connected

at their ends so that fluid forced out of one cylinder by movement of its piston toward its end is caused to flow into the other cylinder as its piston is moved away from its end.
