Abstract
An oil reservoir chamber 22 in an engine E is formed into a tubular shape having annular corner portions 22a and 22b at opposite ends, and an oil slinger 25 is secured to a crankshaft 13 and has two splashing blades 25a and 25b with their tip ends being in proximity to the corner portions 22a and 22b, so that a lubricating oil in the oil reservoir chamber 22 is splashed by at least one of the two splashing blades 25a and 25b during rotation of the oil slinger 25 with any operative position of the engine E. Thus, a lubricating oil mist can be produced with any operative position of the engine E by the oil slinger of a simple structure including the two blades.
Claims5
A system for producing a lubricating oil mist in an engine, comprising an oil reservoir chamber (22) provided in an engine body (1), an oil slinger (25) secured to a crankshaft (13) or a rotary shaft operatively associated with the crankshaft (13) for splashing a lubricating oil (O) stored in the oil reservoir chamber (22) to produce an oil mist, wherein
- said oil reservoir chamber (22) is defined into a tubular shape having, at opposite ends thereof, annular corner portions (22a and 22b) with a center thereof being provided by a rotational axis of the oil slinger (25), and said oil slinger (25) is comprised of a boss (25c) fitted over the crankshaft (13) or the rotary shaft operatively associated with the crankshaft (13), two splashing blades (25a and 25b) extending from said boss (220) with tip ends thereof being positioned in proximity to one of the corner portion (22a) of the oil reservoir chamber (22) and the other corner portion (22b), wherein with any operative position of the engine (E), the lubricating oil (O) within the oil reservoir chamber (22) is splashed by at least one of said splashing blades (25a and 25b).
