Valve mechanism lubrication system for an overhead valve engine
In an internal combustion engine, including a crankcase, an oil sump, push rods for operating the valves of the engine, a rocker box for housing the valve actuating mechanism, a lubrication system for lubricating the valve actuating mechanism is described which consists of: a first hollow tube for housing a first of the push rods, and first tube having one end open to the crankcase, and an opposite end open to the rocker box, for conducting oil mist from the crankcase to the rocker box to lubricate the valve rocker mechanism; a second hollow tube for housing a second push rod, the second tube having one end open to the rocker box and an opposite end open to a breather chamber for conducting liquid oil and oil mist from the rocker box to the breather chamber, the breather chamber being vented to the atmosphere; an oil drain passage for conducting liquid oil from the breather chamber to the oil sump; and baffle means in the rocker box for causing the oil mist entering the rocker box from the first tube to flow past the valve actuating mechanism for lubrication thereof before flowing from the rocker box into the second tube.
