Abstract
A valve and a hydraulic controller are provider. The valve may combine a rotary-to-linear converter with the hydraulic controller to provide for at least two mechanisms for actuating the valve. Additionally, the valve may include a mechanical lock mechanism suitable for securing the valve at a desired flow position. The mechanical lock mechanism may also provide overload protection. That is, the mechanical lock mechanism may “slip” or disengage if torque forces reach undesired levels. The hydraulic controller may enable a “stepping” mode of control and “fast actuation” mode of control. The “stepping” mode may deliver a discrete quantity of a fluid, while the “fast actuation” mode may deliver a continuous quantity of the fluid.
Claims21
A system comprising:
- a hydraulic control system comprising:
- a first valve configured to deliver a fluid through a first fluid path to actuate a device;
- a first piston disposed in a cylinder and configured to deliver a discrete quantity of the fluid to the first valve through a second fluid path;
- a second valve configured to provide the fluid to the first piston through a third fluid path;
- and
- a third valve configured to provide a continuous quantity of the fluid through the second fluid path to the first valve.
A system comprising:
- a hydraulic control system comprising:
- a discrete hydraulic supply system configured to supply a plurality of discrete quantities of a hydraulic fluid to drive a hydraulic system in a stepwise manner;
- and
- a continuous hydraulic supply system configured to supply a continuous flow of the hydraulic fluid to drive the hydraulic system in a continuous manner, wherein the hydraulic control system is configured to operate the discrete hydraulic supply system and the continuous hydraulic supply system independently from one another.
A system comprising:
- a controller configured to control a hydraulic system;
- wherein the controller is configured to control a plurality of discrete quantities of a hydraulic fluid provided to the hydraulic system and a continuous flow of the hydraulic fluid provided to the hydraulic system.
