Abstract:
A system for detecting leaks in a hydraulic supply system for a double-acting hydraulic actuator is disclosed. The system may include a first conduit in fluid communication with a first chamber of the actuator, and with a second chamber of the actuator, and a directional control valve coupled with the first conduit and the second conduit. A directional control valve may be in fluid communication with a hydraulic oil supply line and may switch between the hydraulic oil being sent and received via the first conduit and second conduit. A valve can be associated with the oil supply line. A first and second flow meter can generate a first signal and a second signal, respectively, indicating flow rate within the first conduit and the second conduit. A controller may receive the first signal and the second signal, calculate their ratio, and cause the valve to inhibit flow within the oil supply line upon the ratio differing from a given ratio by more than a predetermined threshold.

Claim (Index 3):
The system according to  claim 1  for detecting leaks in a hydraulic supply system for a double-acting hydraulic actuator, wherein the first flow meter comprises:\n a first flow meter chamber in fluid communication with the first conduit; \n a first flow meter piston disposed within the first flow meter chamber, movable in two directions responsive to a direction of drag force exerted by hydraulic oil flow through the first flow meter chamber; and \n a first flow meter linear displacement sensor, configured to detect a relative position of the first flow meter piston within the first flow meter chamber, and to generate the first signal based on the detected relative position of the first flow meter piston.
