Abstract
A rotary disc of a speed-regulating centrifugal governor driven by a crank shaft is rotatably fitted to a crank case of an engine. While part of the rotary disc is immersed in lubricating oil stored in the crank case, the rotary disc is disposed adjacent to a timing gear and impeller blades project from the outer peripheral face of the rotary disc so as to form an impeller. Further, guide walls for guiding oil splashed by the rotation of the impeller to the timing gear 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.
Claims3
In an engine having a valve mechanism including at least one valve, and a crank shaft supported by a crank case is coupled via a timing gear to a valve cam shaft supported by a cylinder head, a valve mechanism lubricator for such an engine, comprising:
- a lower portion of the crank case defining an oil storage chamber;
- an impeller driven by the crank shaft to splash lubricating oil stored in the oil storage chamber disposed adjacent the timing gear;
- and guide walls formed along the inside wall of the crank case and operative to guide the oil splashed by the impeller to the timing gear.
