    Abstract: A lubricating system for a two cycle internal combustion engine as applied to an outboard motor wherein small amounts of lubricant can be pumped by a diaphragm type pump through the use of an air bleed that mixes air with the lubricant being pumped. Pulsation variations are minimized by supplying the pump with lubricant with a constant volume delivery chamber.

    Abstract: A piston for internal combustion engines, which has inclined surface portions in the skirt area to allow formation of hydrodynamic wedges of lubricant, these surface portions being constructed as skirt recesses (13 or 14) which are open either towards the upper or towards the lower end of the piston skirt. The transition zone from these skirt recesses to the bearing surface of the working surface of the piston is constituted by oblique surfaces which are inclined inwardly from the surface of the skirt. The oblique surfaces terminate in a circumferential direction within the bearing surfaces of the piston. The oblique surfaces constitute ramps on which a hydrodynamic wedge of lubricacting oil can form. The particular advantage of disposing the oblique surfaces in skirt depressions which are only open at one end lies in that when the hydrodynamic wedge of lubricating oil builds up as a result of the translatory motion of the piston, the oil which forms the wedge of lubricant cannot escape in a peripheral direction which thereby increases the frictional quality (or aqua-planing effect) between the working surfaces of the piston and cylinder.

    Abstract translation: 一种用于内燃机的活塞,其在裙部区域中具有倾斜的表面部分以允许形成润滑剂的流体动力楔,这些表面部分被构造为裙部凹口(13或14),其朝向上部或下部开口 的活塞裙。 从这些裙部凹部到活塞的工作面的支承面的过渡区域由从裙部的表面向内倾斜的倾斜面构成。 倾斜表面在活塞的支承表面内沿圆周方向终止。 倾斜表面构成其上可形成润滑油的流体动力楔的斜面。 将倾斜表面设置在仅在一端开口的裙部凹陷中的特别优点在于当润滑油的流体动力楔由于活塞的平移运动而积聚时,形成润滑剂楔的油不能 在圆周方向上逸出,从而增加活塞和气缸的工作表面之间的摩擦质量(或水平面效应)。
