Abstract: An engine is formed with a valve lifter bore with a lubricant supply opening, positioned at an axially intermediate point therealong, to which is communicated a passageway to which lubricating oil is supplied under pressure. This lubricant supply opening could be used together with a hydraulic type valve lifter. The engine also has a means (such as a cam shaft) for reciprocating a valve lifter in the valve lifter bore along a determinate stroke. The mechanical valve lifter construction of this invention includes a generally cup shaped valve lifter, with an outer cylindrical surface slidably inserted in the valve lifter bore and with an internal hollow, formed with a generally radially extending lubricant escape hole through its side from its internal hollow to its outer cylindrical surface. The lubricant escape hole opens to the outer cylindrical surface of the valve lifter at such a position that, when the valve lifter is slidably inserted in the valve lifter bore and is reciprocated therein by the reciprocating means, the lubricant escape hole does not come into register with the lubricant supply opening at any time during the movement of the valve lifter along its determinate stroke. Thereby, spurting out of the pressurized lubricating oil through the lubricant escape hole is positively prevented. This mechanical valve lifter construction thus can be applied to an engine cylinder block to which, alternatively, a hydraulic valve lifter construction can also be applied, and thus an economy in the number of parts required is effected.
