Abstract
An idling speed adjusting mechanism for injection pumps in which a pivotal connection for raising the idling rotational speed is adjustable against a spring force by way of an adjusting mechanism arranged externally at the pump housing and adjustable against the spring force. The adjusting mechanism includes an adjusting motor formed in particular by an expansion element which is extensible with a temperature increase in the spring prestress direction. The adjusting motor is connected with the pivotal spring connection by way of an intermediate member displaceable between abutments fixed at the housing. The intermediate member, in turn, is spring-loaded with a temperature increase opposite the extension direction of the adjusting piston of the adjusting motor.
