Centrifugal switch for electrically controlled fuel injection system - comprises centrifugal pendulum secured to rotating carrier member by metal strip support and switch securing relative to housing

摘要

A switch (23') is secured relative to the housing and has a switching clearance (A) relative to an actuating pin (25). The pendulum (13') carries a mass (14) on an arm (13a') which extends in the direction of the axis of rotation (D), and its second lever arm (13b') extends approx. at right angles to the axis of rotation (D) and, together with the metal strip support (16), is held in abutment against a rolling surface on the carrier member (12') by a return spring (18), and pref. by an additional spring clip (39). The spring constant of the return spring (18) is such that the increase in the force of the spring is less than the corresp. increase in centrifugal force when the pendulum (13') swings outwardly.
