A rocker arm for fuel injector operation in a combustion engine wherein the rocker arm transmits driving power from an overhead camshaft to a fuel injector of unit type. The rocker arm has at least one non-metallic spring element which is incorporated as a resilient link in the power transmission between the camshaft and the fuel injector. The spring element prevents too great forces being transmitted to the fuel injector and the pump piston of the injector. The spring element may take the form of a cylindrical bushing about the rocker arm bearing at the engine to be between the rocker arm and its shaft on the engine and/or about a cam follower shaft on the rocker arm and between the cam follower shaft and a cam follower supported on that shaft. |
