Abstract
A fuel injection pumping apparatus includes an axially movable member which at one end is acted upon by governor weights and at its other end is acted upon by a spring, the governor weights moving the member in opposition to the spring, the reaction member for the weights comprising a dash-pot containing a further spring and the member being provided with a groove which can register with a port to control the flow of fuel delivered by the pumping apparatus to the associated engine. Also provided on the member is a further groove which is in restricted communication with the groove and which during certain conditions of rapid deceleration of the engine, is brought into communication with the port so as to ensure that under such conditions a restricted flow of fuel takes place to the engine.
