Rotary actuator with piston and pressure chamber assembly
The patent US12012976B2 describes a rotary piston actuator assembly designed for efficient rotary actuation. The assembly includes a first rotary actuator featuring a pressure chamber assembly that defines a central bore and an arcuate chamber. This chamber contains an arcuate-shaped piston that moves reciprocally, with a connector arm affixed to the piston and extending to an outer housing. The actuator is equipped with a fluid delivery shaft that facilitates the flow of pressurized fluid through various ports, enabling the piston to generate rotary motion. The design allows for the creation of multiple pressure chambers, enhancing the actuator's functionality and responsiveness.
Additionally, the patent outlines methods for rotary actuation, including the provision of pressurized fluid to the actuator, which urges the piston outward to rotate the outer housing. The assembly can be reconfigured for different operational setups, allowing for flexibility in application. The actuator can also be integrated into a machine apparatus, where it serves as a joint connecting two arm portions. The detailed claims emphasize the structural components, such as seals and fluid transmission paths, which are critical for maintaining pressure and ensuring efficient operation. Overall, the invention presents a sophisticated solution for rotary actuation in various mechanical applications.
