In a multi-cylinder fuelinjection pump, the pistons 12 are actuated by cams 18 through the medium of cam followers 11 guided in bores in the pump housing. To prevent rotation of the cam followers, flats 20 are provided on adjacent surfaces which engage a pin 21 mounted transversely in the pump housing; the pin may be fixed or rotatably mounted. The flats may penetrate the material of the cam follower to form an opening to vent the space 24.
