Technical field

The present invention relates to fuel pump fields, and in particular to a kind of fuel pump of integrated siphon and fluidic architecture.

Background technique

With advances in technology, jet pump is commonly used on electric fuel pump assembly, which can make automobile in low oil Auxiliary fuel tank inner fluid remains full oil condition when position, and can guarantee in this way can be quick in the insufficient situation of liquid level of fuel oil in fuel tank Starting.Jet pump formation negative pressure rear fuel tank internal combustion oil stream, which enters auxiliary fuel tank, simultaneously can play the role of cooling electric fuel punp, mention High oil pump service life, at present in automobile fuel pump industry, generally use single fluidic architecture realize oil storage barrel it is full by Function, for the fuel tank of the shape of a saddle, assembly has auxiliary fuel tank connecting pipeline, it is necessary to separately design two groups of fluidic architectures to meet Oil storage barrel is full by the intake function with auxiliary fuel tank fuel oil, and such design separates two groups and separately designs, and space occupancy rate is higher, design Difficulty is very big, and higher cost.

Summary of the invention

Technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art,

The fuel pump of a kind of integrated siphon and fluidic architecture is provided.

To achieve the above object, the present invention provides the following technical scheme that a kind of fuel oil of integrated siphon and fluidic architecture Pump, includes shell, it is characterised in that: housing bottom surface is provided with tee of jet current body, and the enclosure interior is in tee of jet current body one End is provided with the main oil inlet pipe being connected to tee of jet current body, and the other end of the opposite connection tee of jet current body of the main oil inlet pipe is tool Have a primary input end of oil inlet, the tee of jet current body be oppositely arranged main oil inlet pipe it is ipsilateral be provided with tee of jet current body Connection and spaced first jet nozzle and the second jet nozzle, be provided in the shell respectively with the first jet nozzle And second jet nozzle connection siphon jet structural tube.

By adopting the above technical scheme, by the way that the first jet nozzle and the second jet nozzle, In are arranged on tee of jet current body Jet pipe is connected at second jet nozzle, connection and the integrally formed siphon jet pipe of main oil inlet pipe at the first jet nozzle will Fluidic architecture is divided into two-way jet stream, is connected to oil storage barrel fluidic architecture all the way, is connected to auxiliary fuel tank syphon structure all the way, while realizing storage The siphon function of oily jet stream and auxiliary fuel tank, not only structure is simple and function is reliable.

The fuel pump of a kind of above-mentioned integrated siphon and fluidic architecture can be further arranged to: the siphon jet structural tube It include the siphon jet pipe being connect with the first jet nozzle, the jet pipe being connect with the second jet nozzle, siphon jet pipe one Side and main oil inlet pipe, which offset, has gap between the other side and jet pipe, the siphon jet pipe is close to the one of the first jet nozzle End side wall offers siphon import.

By adopting the above technical scheme, the fuel oil entered at the primary input end of main oil inlet pipe passes through tee of jet current body rear portion Flow into siphon jet pipe another part from the first jet nozzle and then pass through the second jet nozzle and enter jet pipe, siphon jet pipe with Jet pipe between the two there is gap to be separated independently of each other, be provided with rainbow at the first jet nozzle in siphon jet pipe Suction inlet, when fuel oil passes through siphon jet pipe, siphon inlet generates negative pressure, and the fuel oil of auxiliary fuel tank sucks siphon from there and penetrates It is compact-sized and practical in flow tube.

The invention has the benefit that fluidic architecture is divided into two-way jet stream by tee of jet current body, it is connected to oil storage all the way Bucket fluidic architecture, is connected to auxiliary fuel tank syphon structure, while realizing the siphon function of oil storage barrel jet stream and auxiliary fuel tank all the way, not only ties Structure is simple and function is reliable.

Invention is further described in detail with reference to the accompanying drawings and examples.
