Abstract
The invention provides a supercharged engine vacuum boosting system in order to overcome the defects of existing supercharged engine vacuum boosting and solve the problem that an intake manifold of a supercharged engine is insufficient in vacuum degree. The supercharged engine vacuum boosting system comprises an engine, a mechanical vacuum pump, a tee joint, a vacuum booster, a first one-way valve, a second one-way valve and a third one-way valve. An intake manifold on the engine is communicated with an air outlet of the first one-way valve through a hose. An air inlet of the first one-way valve is communicated with a first air outlet of the tee joint through a hose. An extraction opening of the mechanical vacuum pump is communicated with an air outlet of the second one-way valve through a hose. An air inlet of the second one-way valve is communicated with a second air outlet of the tee joint through a hose. An air inlet of the tee joint is communicated with an air outlet of the third one-way valve through a hose. An air inlet of the third one-way valve is communicated with an air outlet of the vacuum booster through a hose. The supercharged engine vacuum boosting system is simple in structure and reliable in operation, and the vacuumizing capacity is far higher than that of a vacuum system of a common mechanical vacuum pump.
Description
Technical field
Patent of the present invention belongs to the technical field of automobile turbo engine vacuum system, is for various passenger cars, minicar design
A kind of engine with supercharger vacuum boost system.
Background technology
Brakes vacuum boost system vacuum is all to be produced by motor intake manifold, and is connected to vacuum by vacuum line
Booster.Along with the development of current engine technology, the employing of engine with supercharger technology, motor intake manifold is interior in major part
Being malleation (more than atmospheric pressure) under operating mode, although remaining in inlet manifold produce vacuum, but not reaching far away vacuum booster
Needs, make the braking of automobile bring difficulty, also make partial vacuum control valve normally to work.Therefore, design a kind of new
It is particularly important that vacuum system has ensured that brakes normally works.
Summary of the invention
The present invention, in order to overcome the vacuum-assisted weak point of existing engine with supercharger, solves supercharged engine inlet manifold vacuum
Not enough problem.There is provided for the normally work such as car load brakes, vacuum control valve a kind of simple in construction, the one of reliable operation
Plant engine with supercharger vacuum boost system.
The present invention solves that above-mentioned technical problem adopts the following technical scheme that:
A kind of engine with supercharger vacuum boost system, including engine, oil-sealed rotary pump, it is characterised in that also include three-way connection,
Vacuum booster, the first check valve, the second check valve and the 3rd check valve, it is characterised in that: the inlet manifold on engine is led to
Crossing the gas outlet connection of flexible pipe and the first check valve, the air inlet of the first check valve is by the first gas outlet of flexible pipe with three-way connection
Connection；The bleeding point of oil-sealed rotary pump is connected by the gas outlet of flexible pipe and the second check valve, and the air inlet of the second check valve passes through
Flexible pipe connects with the second gas outlet of three-way connection；The air inlet of three-way connection is connected by the gas outlet of flexible pipe and the 3rd check valve,
The air inlet of the 3rd check valve is connected with the gas outlet of vacuum booster by flexible pipe.
Compared with prior art it is an advantage of the current invention that:
Owing to remaining this function of air started in inlet manifold extracting vacuum booster, when engine idle or the slow-speed of revolution
Time, motor intake manifold vacuumizes with oil-sealed rotary pump simultaneously, and engine has the feature that the big rotating speed of discharge capacity is high so that take out
Vacuum capacity is far longer than the vacuum system vacuumized only with oil-sealed rotary pump, this guarantees the sound of vacuum booster vacuum
Between Ying Shi, the vacuum system of ratio simple use oil-sealed rotary pump is short.
Accompanying drawing explanation
Fig. 1 is a kind of engine with supercharger vacuum boost system schematic diagram of the present invention.
In figure: 1. engine, 2. oil-sealed rotary pump, 3. three-way connection, 4. vacuum booster, 5. the first check valve, 6. second
Check valve, 7. the 3rd check valve.
Specific embodiments
Below in conjunction with the accompanying drawings patent of the present invention is further described:
In FIG, the inlet manifold on engine 1 is connected by the gas outlet of flexible pipe and the first check valve 5, the first check valve 5
Air inlet connected with the first gas outlet of three-way connection 3 by flexible pipe, it is unidirectional that control air is led to motor intake manifold by three
Flowing.Oil-sealed rotary pump 2 is driven by engine, and the inlet manifold on engine 1 is given vent to anger by flexible pipe and the first check valve 5
Mouth connection, the air inlet of the first check valve 5 is connected with the first gas outlet of three-way connection 3 by flexible pipe, controls gas by threeway
To vavuum pump one-way flow.The air inlet of three-way connection 3 is connected by the gas outlet of flexible pipe and the 3rd check valve 7, and the 3rd is unidirectional
The air inlet of valve 7 is connected with the gas outlet of vacuum booster 4 by flexible pipe, controls air by vacuum booster to threeway way flow
Dynamic.The direction that in Fig. 1, arrow points to is air-flow direction.
The operation principle of a kind of engine with supercharger vacuum boost system of the present invention is: before starting booster work, start
Being negative pressure at the inlet manifold of machine 1, the air in vacuum booster 4 flows to three-way connection 3 through the 3rd check valve 7, then by
Three-way connection 3 flows to the inlet manifold of air inlet engine 1, and oil-sealed rotary pump 2 is by driven by engine simultaneously, also can produce negative pressure,
Also some flows to oil-sealed rotary pump 2 to air in vacuum booster 4；When the booster of engine 1 works, engine 1
Inlet manifold at be changed into malleation by negative pressure, the first check valve 5 between inlet manifold and the three-way connection 3 of engine 1 closes
Closing, the air in vacuum booster 4 flows to oil-sealed rotary pump 2 through three-way connection 3.
