A mechanical valve lifter for an internal combustion engine comprises a head section having a recessed portion on an upper face thereof, a skirt section formed integral with the head section and adapted to be in sliding-contact with a lifter guiding bore in an engine cylinder head, a mechanical valve-clearance adjusting shim put in the recessed portion, an annular groove formed in an upper face of a bottom wall of the recessed portion of the lifter body, a first through-opening formed in the shim to communicate with the annular groove, and a second through-opening formed in the head section to communicate with the annular groove and to penetrate the head section. The annular groove and the second through-opening are formed in an essentially zero bending moment area midway between a central axis of the head section and a peripheral wall of the recessed portion.

A fuel filter is disposed in a fuel supply line connecting a fuel tank to a fuel injection pump of a diesel engine, and provided with a fuel passage through which a warmed overflown fuel from the fuel injection pump is supplied to the upstream side of a filter element of the fuel filter. A check valve is disposed in the fuel passage of the fuel filter and adapted to be openable to allow the warmed fuel to flow through the fuel passage. Additionally, a bimetal element is disposed to be operatively connectable with the check valve to cause the check valve to open in response to the temperature of the fuel within the fuel filter.
