The floating tappet guide plate(60) is provided for an I.C. engine having three tappets (40, 42, 44) per cylinder. The guide plate is mounted for movement on the central tappet(40) and is shaped to co-operate with mating surfaces on the remaining tappets to prevent rotation of all three tappets. The tappet guide plate is secured to the circumference of the injector tappet(40) so as to form an integral part of it, and includes opposed squared projections (64, 66) which extend toward corresp. flat guide surfaces (50, 51) of the outer two valve tappets (42, 44). This permits the valve tappets to move freely in a vertical direction while simultaneously preventing their rotation.
