Abstract
A mechanical governor of the so-called 'idling and maximum speed governor' type for injection pumps, comprising a governing lever to which is connected the control member for the rate of flow, or metering member, and which is pivotally mounted under the action of a force which is a function of the engine rotation speed, an idling speed spring bearing, on the one hand, on the governing lever and, on the other hand, on an idling speed abutment member, a control lever the position of which determines the engine speed at idling speed and the maximum speed and the load, or rate of flow delivered to the engine, at the intermediate speeds, and a main spring connected, through one of its ends, to the control lever, and through its other end to a rigid piece located at a certain distance of the governing lever, and in such manner as to be engaged with said lever and then to pivot when the control lever is moved from its idling speed position towards its maximum speed position, a regulator wherein the idling speed abutment member and the rigid piece to which is connected the main spring are two distinct parts, so that the idling speed spring is independent of the control lever.
