内燃机的润滑油供给装置
摘要：
本发明提供一种内燃机的润滑油供给装置，该内燃机的润滑油供给装置在平衡轴的一端具有润滑油泵，并且无需在平衡轴设置油路。润滑油泵（25）与平衡轴（13）的一端连接。润滑油泵（25）具有内转子（56）和外转子（58），内转子（56）具有多个齿，外转子（58）的齿数比内转子（56）的齿数多，所述平衡轴（13）的一端以旋转自如的方式支承于轴承（18），在该轴承（18）与所述内转子（56）及所述外转子（58）之间设有密封板（65）。吸入油路（48）设于曲轴箱（11）的壁厚内，该吸入油路（48）将润滑油引导到润滑油泵（25）。排出油路（49）设于曲轴箱（11）的壁厚内，该排出油路（49）将利用润滑油泵（25）进行加压后的润滑油引导到轴内油路（53）。
摘要（英）：

The invention provides a lubricating oil supply device for an internal combustion engine, wherein one end of a balancer shaft of the lubricating oil supply device for an internal combustion engine is provided with a lubricating oil pump, while no oil conduit is required to be provided within the balancer shaft. The lubricating oil pump (25) is connected with one end of the balancer shaft (13). The lubricating oil pump (25) comprises an inner rotor (56) and an outer rotor (58). The inner rotor (56) is provided with a plurality of teeth, and the number of the teeth of the outer rotor (58) is greater than the number of the teeth of the inner rotor (56). One end of the balancer shaft (13) capable of rotating freely is supported by a bearing (18). Sealing plates (65) are arranged among the bearing (18), the inner rotor (56) and the outer rotor (58). An intake oil conduit (48) for directing lubricating oil into the lubricating oil pump (25) is disposed inside the wall thickness of a crankcase (11). A discharge oil conduit (49) for directing lubricating oil pressurized in the lubricating oil pump (25) to the in-shaft oil conduit (53) is disposed within the wall thickness of the crankcase.
