Abstract: A centrifugal force sensing device is disclosed, which includes a first rotating shaft, two first movable and two first fixing sleeves, a first and a second weight, two first and two second linkages, a restoration element, a first sensing unit for sensing centrifugal force, and two fixers. The two first movable sleeves are disposed through the first rotating shaft. The two first linkages are connected to the first weight and the two first movable sleeves. The restoration element having a fixing block and two first damping elements is disposed at the first rotating shaft. The two second linkages are connected to the second weight and the two first movable sleeves. The two first fixing sleeves are fixed at the first rotating shaft and respectively located between each of the two first movable sleeves and one of the two fixers.

Abstract: An electric centrifugal switch is proposed, in particular for the purpose of safety shutoff upon attainment of a shutoff rpm for fuel injection systems, electrically controlled in an open- or closed-loop manner, of internal combustion engines, which is not vulnerable to rotary oscillations and which effects a rapid shutoff. The centrifugal switch comprises a centrifugal pendulum secured by means of a metal band bearing on a revolving carrier element and a switch attached to the housing and provided with a switching distance from an actuation pin. The centrifugal pendulum carries a flyweight mass on the end of a first lever arm extending substantially in the direction of the rotary axis, and its second lever arm extending at least approximately rectangularly to the rotary axis, is held together with a metal band of the band bearing in constant contact on a roll-off surface located on the carrier element by a restoring spring and, in a preferred embodiment, by means of a supplementary spring element.

Abstract: The flyweights of a governor of the general kind having magnetised flyweights and a field coil for modifying the bias of the flyweights, are magnetised by applying a voltage pulse to the coil when the governor is stationary.
