Valve mechanism lubricator of engine

摘要

A rotary disc of a speed-regulating centrifugal governor (19) driven by a crank shaft (2) is rotatably fitted to a crank case of an engine. While part of the rotary disc (21) is immersed in lubricating oil stored in the crank case, the rotary disc (21) is disposed adjacent to a timing gear and impeller blades (25a) project from the outer peripheral face of the rotary disc (21) so as to form an impeller (25). Further, guide walls (291 and 292) for guiding oil splashed by the rotation of the impeller (25) to the timing gear (12) are integrally formed with the inside wall of the crank case, so that the timing gear of a valve mechanism can be effectively lubricated with the splashed oil. <IMAGE>
