Title: Fuel injection pumps

A fuel injection pump of the rotary distributor type includes a cam actuated plunger housing in a bore and an adjustable fuel control member which varies the amount of fuel supplied to the bore. The pump also includes a timing piston connected to the cam, the piston being biased by a spring against the action of fuel under pressure. In order to vary the timing under certain conditions a control piston serves as an abutment for the spring and the application of pressure to the control piston is controlled by a valve which has a valve element coupled to a throttle member of the pump the valve having a housing which is secured on the exterior of the pump.
