Abstract

The invention discloses an automatic emptying device for fuel oil. The automatic emptying device for the fuel oil comprises a housing, an installation support, a water collection cup, a filter elementassembly, an electric oil delivery pump assembly and at least one check valve assembly. The housing, the installation support and the water collection cup define a chamber. The installation support is provided with an oil inlet port of the emptying device, and the water collection cup is provided with an oil outlet port of the emptying device and a heating device. The filter element assembly is arranged in the chamber, and provided with an inner cavity. The upper part of the electric oil delivery pump assembly is inserted into the inner cavity of the filter element assembly, and the lower endof the electric oil delivery pump assembly stretches into the inner cavity of the water collection cup. The electric oil delivery pump assembly comprises an electric oil delivery pump and an electricconnector; and the electric connector is provided with a fuel oil channel and bypass holes which are as many as the check valve assemblies. An air inlet port of the fuel channel communicates with anoil outlet port of the electric oil delivery pump, and an oil outlet port of the fuel channel communicates with the oil outlet port of the emptying device. The at least one check valve assembly is arranged in the at least one bypass hole separately in the manner of one-to-one correspondence. The automatic emptying device for the fuel oil is compact in structure, easy to machine and manufacture, and good in heating effect on the fuel oil in the water collection cup.

Description

technical field

[0001] The invention relates to a fuel automatic emptying device. Background technique

[0002] When the automobile fuel engine is started at low temperature and low speed, the low-pressure oil circuit often cannot automatically empty the air in the oil circuit, which causes the fuel engine to start unstable, difficult to start, or even unable to start, which affects the use of customers experience. Therefore, it is usually necessary to increase the automatic emptying device of automatic emptying and fast oil supply on the fuel engine.

[0003] The existing automatic fuel emptying device includes a filter element assembly, a filter element assembly base, an electric fuel delivery pump assembly, a one-way valve assembly, and a water collection cup. On the base, it not only takes up a lot of space, but also needs to process the electric fuel pump assembly cavity, check valve assembly cavity, fuel discharge channel, bypass oil circuit, etc. on the filter eleme...
