Abstract
A rotary vane type actuator includes a vane assembly for converting pressure from a pressurized medium within the actuator into rotational movement. The vane assembly has a rotatable vane and a vane seal for preventing leakage of pressurized medium through or around the vane assembly. A side-plate is attached to the rotatable vane and the side-plate has a limiting protrusion that abuts the vane to maintain a gap between the vane and the side-plate so that the seal in the gap is not extruded from between the vane and side-plate.
