Abstract
A speed limiter for an elevator installation includes a stand, a wheel rotatably mounted on the stand and a non-circularly extending guide surface rotatable with the wheel. A pendulum, which is pivotable relative to the stand, with a pendulum wheel bearing against the guide surface is provided. In addition, a restraining device is provided, which loads the pendulum wheel at least indirectly with a restraining force against the guide surface. A switching vane connected with the pendulum comes into engagement with a blocking dog, which dog is connected at least indirectly with the wheel, when the pendulum is pivoted out to a certain extent in which the pendulum wheel lifts off the guide surface. In addition, an actuating device that triggers the engagement between the switching vane and the blocking dog is provided.
