Abstract
The utility model relates to an air inlet manifold for a one-way valve of a ventilation system of an integrated crank box. A membrane type one-way valve is directly fixed in the inlet manifold. According to the air inlet manifold provided by the utility model, the membrane type one-way valve is directly fixed in the air inlet manifold, so that the membrane type one-way valve is far from a high-temperature position of an engine. Therefore, not only can pipelines outside the engine be concise, but also the leakage risk of the external pipelines can be reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of arrangement of crankcase ventilation system one-way valve, especially relates to a kind of intake manifold of integrated crankcase ventilation system one-way valve.
Background technique
At present, the crankcase ventilation system one-way valve of motor generally has two kinds of arrangements:
A kind of is externally connected type, and one-way valve is arranged in the middle of the pipeline, and two ends connect with flexible pipe and fix with clip, and this form makes line arrangement complicated, and has increased the risk that pipeline is revealed;
A kind of in addition is one-way valve to be integrated in cyclinder head cover cover, though this kind mode makes line arrangement simple, one-way valve is in the environment work of high temperature all the time, and life problems is affected by environment bigger.
Summary of the invention
The utility model has designed a kind of intake manifold of integrated crankcase ventilation system one-way valve, and the technical problem of its solution is that the crankcase ventilation system one-way valve arrangement of available engine exists complicated layout and increases the risk of leakage or be integrated in cyclinder head cover and covers the environment that makes one-way valve be in high temperature all the time easily and have influence on working life.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of intake manifold of integrated crankcase ventilation system one-way valve, diaphragm type one-way valve directly is fixed in the intake manifold.
Further; Said diaphragm type one-way valve comprises one-way valve base (2), check valve sheet (3) and one-way valve cover plate (4); One-way valve base (2) is fixedly connected with one-way valve cover plate (4); One-way valve base (2) and one-way valve cover plate (4) are fixed on the intake manifold body (1) simultaneously; Triton system suction tude joint merchandiser forms an integral body to valve cover (4); Crankcase ventilation system suction port (5) is positioned on the one-way valve cover plate (4), and the running shaft Spielpassung of the groove of unidirectional valve seat (2) and check valve sheet (3), check valve sheet (3) are cut off or conducting around the running shaft rotation and to intake manifold and triton system between one-way valve base (2) and one-way valve cover plate (4).
Further, check valve sheet (3) different at different position and different is used material different, said check valve sheet (3) near the material density at running shaft position greater than the material density of said check valve sheet (3) away from the running shaft position.
Further, one-way valve cover plate (4) is fixed through the mode and the intake manifold body (1) of welding.
The intake manifold of this integrated crankcase ventilation system one-way valve has following beneficial effect:
The utility model is owing to directly be fixed on diaphragm type one-way valve in the intake manifold; Make diaphragm type one-way valve away from the engine high-temperature position; Thereby make the external engine pipeline more succinct on the one hand, and reduced the risk that exterior line is revealed simultaneously again, prolong its working life.
Description of drawings
Fig. 1: the check valve sheet of the intake manifold of the integrated crankcase ventilation system one-way valve of the utility model is descended structural representation in off position;
Fig. 2: the check valve sheet of the intake manifold of the integrated crankcase ventilation system one-way valve of the utility model structural representation under opening state.
Description of reference numerals:
1-intake manifold body; 2-one-way valve base; 3-check valve sheet; 4-one-way valve cover plate; 5-crankcase ventilation system suction port.
Embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is further specified:
One-way valve fixed base 2 is directly injection-moulded on the intake manifold body 1; Triton system suction tude joint merchandiser forms an integral body to valve cover 4; Crankcase ventilation system suction port 5 is on the cover plate 4 of one-way valve, and one-way valve cover plate 4 follow-up gas manifold body 1 adopt the method for welding to be fixed together.Before welding, earlier check valve sheet 3 is placed on the one-way valve base 2, welds then.Because unidirectional valve seat 2 groove merchandisers are Spielpassung to valve block 3 running shafts; When one-way valve cover plate 4 is welded on the one-way valve base 2; Check valve sheet 3 still can rotate freely around running shaft; So just guaranteed that one-way valve can carry out work under intake manifold and triton inlet two ends produce the effect of pressure reduction, played the effect of resistance ventilation body individual event circulation, guaranteed that gas in the intake manifold can not flow backwards to get into the triton system.
The check valve sheet different at different position and different is used material different, and resistance reduced when valve block was rotated, and sealing reliability improves.
Special construction on the intake manifold makes motor when shutting down, and valve block is in closed condition, avoids the interior gas leakage of engine crankcase in atmosphere, and environment is polluted.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
