Abstract
A device for testing a hydraulic circuit including the actuating cylinder and piston therefor. The testing device comprises a unitary assembly which is adapted to be clamped to the cylinder to be tested and which actuates the piston for pressurizing the associated hydraulic circuit. Sensing elements are incorporated for sensing the pressure applied to the hydraulic circuit and for sensing the amount of travel of the piston of the actuator during a given time period. In this way leaks or flaws in the hydraulic system may be readily detected.
