摘要： A hydraulic system includes a pump, a reservoir, and an actuator system. A hydraulic circuit breaker is arranged to compare fluid flow to and from the actuator system and to shut off this flow in the event the flow to the actuator system is greater than the flow returning from the actuator system by more than a predetermined differential, thereby indicating a leakage condition. A hydraulic circuit breaker reset device is hydraulically connected to the actuator system and to the circuit breaker. When the circuit breaker is in a shut-off condition, the reset device continuously pressure tests the actuator system. If the pressure in the actuator system increases to indicate the absence of fluid leakage, the reset device responds to the pressure increase in the actuator system to provide a reset signal to the circuit breaker. After the circuit breaker is reset to its normal operating position, a timing piston returns the reset device to its normal operating condition.

摘要： The present invention is directed to an improved fail-safe actuator and hydraulic system incorporating the same. The actuator includes energy storage means in the form of a spring adapted to set a control device in a predetermined condition, illustratively in the closed condition, responsive to a failure situation, illustratively, a power failure. The actuator includes a coupling which permits normal operation of the control device without cycling the spring energy storage means, thus increasing the life of the spring and eliminating energy wastage inherent in cocking the spring during each operative cycle.

摘要： A shutoff valve mechanism is placed in a hydraulic system line extending between a source of hydraulic fluid under pressure and a utilizing apparatus such as a subsystem or a hydraulic actuator. Variable orifices disposed in the source and return flow paths produce pressure drops which vary linearly proportional with flow rate. The pressure drops are compared and in the event of a predetermined difference therebetween, the shutoff valve is actuated to isolate system pressure.

摘要： 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.
