Abstract

The utility model discloses a check valve in an engine lubrication system. The check valve which only can convey oil to an engine oil pump is arranged in the middle of an oil conveying pipe between an engine oil tank and the engine oil pump of an engine, an oil inlet pipe of the check valve is connected with the engine oil tank, and an oil outlet pipe is connected with the engine oil pump. The check valve has the advantages that: engine oil can be effectively prevented from returning to the engine oil tank, the oil conveying pipe above the check valve always has the engine oil, when the engine is started again, the engine oil pump can quickly convey the engine oil to all parts, a piston, a turbocharger and other engine parts can be prevented from being abraded, and the service life of a machine can be prolonged; and only one check valve is arranged in the conventional engine oil pump, and the check valve has a simple structure, is convenient to refit, and is low in cost.
本实用新型公开了一种发动机润滑系统中的单向阀。这种发动机润滑系统中的单向阀,在发动机的机油箱与机轴泵之间的输油管中间,接设一个只能向机油泵方向输油的单向阀,单向阀的进油管与机油箱相接,出油管与机油泵相接。优点:一是可有效阻止机油回流入机油箱,保证单向阀上面的输油管中始终有机油,当再次启动发动机后,机油泵可迅速把机油输送到各零部件,避免活塞、涡轮增压器等发动机零部件空磨,延长机器的使用寿命。二是只需在现有机油泵中加设一单向阀即可,结构简单,改装方便,成本低廉。
