一种发动机链条润滑装置
摘要：
本实用新型涉及一种发动机链条润滑装置。主要解决了一般的链条润滑装置对润滑油流量控制不准确，润滑油容易泄漏的问题，其包括阀体，在阀体内设有活塞，其特征在于：在阀体上套有喷嘴壳体，所述喷嘴壳体与阀体间留有空隙形成一密封的高压油腔，在喷嘴壳体上设有喷油孔，所述喷油孔与高压油腔相连通，在阀体上设有阀体油孔，高压油腔通过阀体油孔与阀体内油缸相连通。本实用新型的优点是：通过在缸盖油道孔上安装一个链条喷嘴壳体对链传动系统进行润滑，该链条喷嘴壳体采用单向阀结构，通过油压控制润滑油的流量，对润滑油流量控制准确，同时也使得润滑油不易泄漏。
摘要（英）：

The utility model relates to a device for lubricating chains of engines and mainly solves the problems in the common devices for lubricating chains that flow of lubricating oil can not be controlled accurately and the lubricating oil is easy to leak. The device comprises a valve and a piston arranged inside the valve and is characterized in that a nozzle shell is sleeved on the valve; a gap is reserved between the nozzle shell and the valve to form a sealed high pressure oil chamber; an oil spray hole is formed on the nozzle shell and communicated with the high pressure oil chamber; an oil hole is formed on the valve; and the high pressure oil chamber is communicated with an oil cylinder inside the valve via the oil hole formed on the valve. The device for lubricating the chains of the motors has the advantages that the nozzle shell is arranged above a hole formed on an oil passage of a cylinder cover for performing lubrication to transmission system of the chains and the nozzle shell adopts the structure of a one-way valve for controlling flow rate of the lubricating oil by using oil pressure, so as to achieve accurate control to the flow rate of the lubricating oil and ensure low probability of leakage of the lubricating oil.
