ABSTRACT:
A splash lubricating device for a horizontal or inclined engine comprises an oil-spoon which is fixed to the connecting-rod of an engine having a cylinder installed on a crank case thereof horizontally or obliquely protrusively therefrom and which is provided with an oil-splash portion formed by bending laterally the lower end portion of the oil-spoon. And the oil-splash portion is turned forward by the connecting-rod along an elliptical orbit inclined forward and downward. The posture of the oil-splash portion is settled nearly parallel with an inrush angle thereof relative to the oil near an oil upper limit level in an oil pan in order to lessen the resistance put thereupon and also inclined forward and downward at a smaller angle than an outrush angle thereof relative to the oil near an oil lower limit level in order to attain good lubricating performance as well as lessen the resistance put thereupon. Hence, the splash lubricating device of the present invention accomplished not only the good lubricating performance but also the lessening of the engine power loss.
