ABSTRACT:
A reciprocable plunger fuel injection pump includes a plunger mounted in a pump barrel. A spring abutment is secured to the plunger and is engaged by one end of a spring the other end of which engages a further spring abutment slidable about the barrel. The barrel is provided with transverse apertures which locate balls which are held in an operative position by the abutment. The balls can be engaged by a step on the plunger to limit the outward movement of the plunger.
