Rotor unit assembly with improved pressure port configuration
A rotor unit assembly has been granted a patent (Publication Number: US11994031B2) with a unique design that includes a housing with a chamber, a rotor, and a rotatable hub. The rotor features a main body with a piston and a valve flange, while the hub has a cavity to receive the piston. The housing's end plate includes low pressure, first high pressure, and second high pressure ports strategically positioned to create seals and control fluid flow within the assembly. The rotor and hub are configured to rotate in opposite directions, ensuring precise timing of port openings and closures for efficient operation.
Furthermore, the rotor unit assembly includes multiple rotors spaced around the hub axis, each interacting with the hub to maintain sealing contact and engage the cavity during rotation. The design allows for the isolation of an expansion region within the clearance volume, enhancing performance and efficiency. The assembly's ports are connected to a manifold, with the low pressure port leading to a low pressure chamber and the high pressure ports leading to a high pressure chamber. These chambers are separated to prevent fluid mixing, and the first high pressure port is equipped with a variable valve for flow control. Overall, the patented rotor unit assembly offers a sophisticated and innovative solution for fluid dynamics and pressure management in a compact and efficient design.
