| 摘要 |
The subject matter of this specification can be embodied in, among other things, a rotary vane actuator (1100) that includes a stator having at least one stator vane (470) and a rotor (410) having at least one rotor vane (420) projecting from a central shaft. The rotor vane (420) is adapted to contact the stator vane (470), and a high pressure chamber (460a/460b) is defined by the stator and a first side of the rotor vane and a low pressure chamber (460b/460a) on a second side of the rotor vane (420). The actuator further includes at least a first aperture (462a/462b) connected to the high pressure chamber (460a/460b) a second aperture (462b/462a) connected to the low pressure chamber (460b/460a). A fluid flow passage connects the first aperture (462a/462b) in the high pressure chamber (460a/460b) to the second aperture (462b/462a) in the low pressure chamber (460b/460a). |
