Description

Novel durable automobile engine delivery valve

Technical Field

The utility model relates to the field of power equipment monitoring, in particular to a novel durable oil outlet valve of an automobile engine.

Background

At present, the oil outlet valve is a one-way valve, under the action of the pressure of a spring, the conical surface on the upper part of the valve is tightly matched with a valve seat, and the function of the oil outlet valve is to isolate a high-pressure oil pipe from a cavity at the upper end of a plunger when the oil supply is stopped, so that the oil in the high-pressure oil pipe is prevented from flowing back into an oil injection pump. The lower part of the oil outlet valve is a cross section, so that the diesel oil can be guided and can pass through the diesel oil. A small cylindrical surface is arranged under the conical surface of the oil outlet valve, and is called a pressure reducing ring belt, and the function of the pressure reducing ring belt is to enable the oil pressure in the high-pressure oil pipe to be rapidly reduced when oil supply is finished, so that the oil dripping phenomenon at a spray hole is avoided. When the ring belt falls into the valve seat, the volume above the valve seat is quickly increased, the pressure is quickly reduced, and the spray is quickly stopped. When the oil pump works, the plunger is forced to do up-and-down reciprocating motion under the action of the cam on the camshaft of the oil injection pump and the plunger spring, so that an oil pumping task is completed, and the oil pumping process can be divided into three stages of oil inlet, oil supply and oil return. But the steel ball in the current delivery valve wearing and tearing are great when using, and life is short, and the easy not hard up connection of internals is unstable after current delivery valve uses for a long time, influences the result of use of delivery valve. Therefore, we propose a structure of the oil outlet valve.
