Abstract
An improved r.p.m. regulator of a fuel injection pump for internal combustion engines includes an improved control spring mechanism. The control spring mechanism is connected to one end of a control lever which in turn is connected at its other end to a fuel supply quantity setting member. The control lever serves to actuate the fuel supply quantity setting member in accordance with the forces applied to the control lever by the control spring mechanism and an r.p.m.-dependent force applying structure which applies a force to the control lever in opposition to the force applied by the control spring mechanism. The control spring mechanism includes a compression spring mounted between the control lever and a setting lever, a first connecting member and a second connecting member. The first connecting member is connected to that end of the control spring furthest from the setting lever, while the second connecting member is connected to that end of the control spring furthest from the control lever.
