Abstract

A regulator apparatus controlled by spring tension, such as a centrifugal governor for internal combustion engines wherein the spring characteristic of the regulator spring remains unchanged during operation and a regulator effectiveness which remains the same over a long period of time is attainable and which includes at least one compression spring acting as the regulator spring and inserted between two supports as well as an actuation member to transfer those regulator motions which tend to cause a change in length of the spring over onto the first spring end, which actuation member can tilt about a transverse shaft disposed perpendicularly to the longitudinal axis of the spring, the compression spring intentionally inserted into an installed position such that a point on the front face of the appropriate spring end, which point transfers the largest spring force component onto the spring support associated with the tiltable actuation member lies in a plane extending parallel to the longitudinal shaft of the spring and penetrating the transverse axis of the actuation member so that undesired tilting movements of the actuation member caused by the spring force exerted eccentrical…
