【考案の詳細な説明】
この考案は内燃機関におけるエンジンの冷却水循環装置
に係るものである。[Detailed Description of the Invention] This invention relates to an engine cooling water circulation system for an internal combustion engine.
一般に内燃機関のエンジン冷却水循環装置において、該
エンジンによって駆動される遠心式ウォータポンプに設
けた羽根車の回転板は、エンジンスペースの関係から、
そのウォータジャケット部内においてシリンダライナの
外壁面に極めて近接して設置されている。Generally, in an engine cooling water circulation system for an internal combustion engine, the rotary plate of the impeller provided in the centrifugal water pump driven by the engine is
It is installed in the water jacket portion extremely close to the outer wall surface of the cylinder liner.
その為、このウォータポンプによってウォータジャケッ

の原因となる等の不都合があった。Therefore, when the water pump sends cooling water into the water jacket section, the cooling water stagnates near the gap between the cylinder block and the rotary plate of the impeller facing it and does not circulate. However, there were disadvantages such as the cylinder liner becoming partially heated and causing distortion, and the lubricating oil film within the cylinder liner breaking resulting in seizing and engine failure.
本考案はこのような不都合を解消するため、羽根車回転
板のシリンダライナと対向する側面に複数の突条を突設

ものである。In order to solve this problem, the present invention eliminates the stagnation of cooling water between this surface and the cylinder liner by providing a plurality of protrusions on the side of the impeller rotating plate facing the cylinder liner. It has been improved to promote its circulation.
次に本考案の一実施例を図面によって説明する。Next, one embodiment of the present invention will be described with reference to the drawings.

ジャケット３内で回転する羽根車８を装着する。In the figure, 1 is the cylinder block of the engine, 2 is the cylinder liner, 3 is the water jacket formed between the cylinder block 1 and the cylinder liner 2, and 4 is the cooling water circulation part fixed to one side of the cylinder block 1. In this centrifugal water pump, the outer end of a pump shaft 6 provided in the center of the case 5 is connected to a rotating mechanism such as a pulley via a shaft coupling 7, and the inner end of the pump shaft 6 is connected to a rotating mechanism such as a pulley. An impeller 8 rotating inside the water jacket 3 is attached.

る。A plurality of blades 9 are provided on one side of the rotary plate 8' of this impeller 8, and a plurality of protrusions 10 are provided on the other side that protrude toward the cylinder liner 2 side and extend in the radial direction of the rotary plate 8'. The rotary plate 8' is located close to the outer wall surface of the cylinder liner 2 with a gap 11 in between.
１２はポンプ軸６の軸受、１３は冷却水のシール材であ

となる。According to the present invention configured in this manner, when the impeller 8 rotates due to the rotation of the pump shaft 6, the cooling water flows into the water jacket 3 along the outer periphery of the cylinder liner 2 by the impeller 9 as shown by the arrow. , the cooling water near the gap 11 between the cylinder liner 2 and the rotary plate 8' of the impeller 8 adjacent thereto flows through the protrusion 1 provided on the rotary plate 8'.
Since the water is forced to circulate while being stirred by the water, the water near the gap 11 does not stagnate and constantly circulates.

止するものである。As explained above, the present invention provides a protrusion on the side of the cylinder liner side of the impeller rotation plate of the cooling water circulation pump, so that the cooling water near this surface is always circulated together with other cooling water without stagnation. Since the cylinder liner is cooled uniformly, this prevents local temperature rises and distortions, and the lubricating oil film inside the cylinder liner is always maintained accurately, reliably preventing engine failures due to piston seizure, etc. It is.
