Abstract
Disclosed herein is a rotary vane actuator device with sealing assembly. The device includes a housing and a sealing assembly. The housing has a center opening defining a chamber. The housing includes opposing end plates for surrounding a stator. The stator having an aligned center opening and a rotor within the chamber. Within the chamber there are two openings, one serving as an inlet, the other serving as an outlet for rotational fluid. The rotor includes a vane assembly fixedly connected thereto. When the fluid enters the chamber, the fluid contacts the vane and moves the rotationally in the same direction. Each of the stator and the vane include seal packs. The end plates include sealing members which contact the stator and vane seal packs whether in the static or dynamic condition of the rotor. The combination of the seal packs and the end plate seal form the sealing assembly.
