产品描述

限压阀与机油泵油路并联，其作用是调节、控制主油道的机油压力。为了保证发动机正常工作，主油道的油压必须适当，通过机油泵限压阀能调节主油道的机油压力。当发动机转速增高或机油稠度变大时，机油压力就会增高。此时限压阀自动开启，通过机油泵回油(即机油泵出油口的机油经限压阀流向进油口)，能控制主油道的油压。旁通阀并联在机油粗滤器上，其作用是当滤清器使用的时间超过了更换期之后，纸滤芯被污垢或异物严重堵塞，循环油不能通过滤芯时，为了防止出现润滑系统供油中断，机油粗滤器上旁通阀自动开启，机油经旁通阀直接流入主油道，这样发动机压力润滑部分不会出现断油的现象。

The pressure limiting valve is connected in parallel with the oil circuit of the oil pump, and its function is to regulate and control the oil pressure in the main oil passage. In order to ensure the normal operation of the engine, the oil pressure in the main oil passage must be appropriate, and the oil pressure in the main oil passage can be adjusted through the oil pump pressure limiting valve. When the engine speed increases or the oil viscosity increases, the oil pressure will increase. At this time, the pressure limiting valve automatically opens, and the oil pressure in the main oil passage can be controlled through the oil pump return (i.e., the oil from the oil pump outlet flows through the pressure limiting valve to the oil inlet). The bypass valve is connected in parallel to the oil coarse filter. Its function is to prevent the interruption of lubrication system oil supply when the paper filter element is severely blocked by dirt or foreign objects after the filter has been used for more than the replacement period. In order to prevent the interruption of lubrication system oil supply, the bypass valve on the oil coarse filter automatically opens, and the oil flows directly into the main oil passage through the bypass valve. This way, the pressure lubrication part of the engine will not experience oil interruption.
