Abstract
The utility model relates to the technical field of a fuel injection pump of a diesel, in particular to an efficient fuel injector. The efficient fuel injector comprises a valve body, a needle valve, a mixing chamber, a fuel passage and an air passage, wherein the needle valve is located at the top of the valve body, the mixing chamber is located in an internal cavity of the valve body, both the fuel passage and the air passage are located at the bottom of the valve body and are communicated with the mixing chamber, and two turbulators are respectively arranged at the outlets of the fuel passage and the air passage. The rotary impeller-type turbulators are arranged at the outlets of the fuel passage and the air passage, fuel and air entering the mixing chamber can be scattered and disturbed, intensively mixed, evenly stirred, and then, ejected for combustion from the needle valve in an optimal atomization state, so that the combustion effect is greatly improved, the energy utilization ratio is increased, the energy sources are saved, and the environment is protected.
Description
Technical field
The utility model relates to the diesel injection pump technical field, especially a kind of efficient oil sprayer.
Background technique
Existing oil sprayer is that fuel oil and air are sprayed into a small-sized seal container simultaneously; Rely on ambient pressure with air with spray into liquid nitrogen vaporization device firing chamber after fuel oil mixes; This structure makes fuel oil and air mixing inhomogeneous; Can not fully burn after getting into the firing chamber, firing effect is poor, and causes a series of problems such as energy waste and environmental pollution.
The model utility content
Inhomogeneous in order to overcome existing oil sprayer oil gas mixing, influence firing effect, the deficiency that wastes energy, the utility model provides a kind of efficient oil sprayer.
The utility model solves the technological scheme that its technical problem adopted: a kind of efficient oil sprayer; Comprise valve body, needle-valve, mixing chamber, oil duct and air flue; Needle-valve is positioned at the top of valve body, and mixing chamber is positioned at body cavity, and oil duct and air flue are positioned at the valve body bottom; All be communicated with mixing chamber, the outlet port of oil duct and air flue respectively is provided with a turbulator.
According to another embodiment of the utility model, comprise that further turbulator is the rotary blade structure, the turbulator sense of rotation in oil duct outlet port is opposite with the turbulator sense of rotation in air flue outlet port.
According to another embodiment of the utility model, comprise that further mixing chamber resembles a pear in shape, lower space is big than upper space.
According to another embodiment of the utility model, comprise that further oil duct and air flue all are arc.
The beneficial effect of the utility model is, the wheeled turbulator of pivoting leaf is set in the outlet port of oil duct and air flue, can break up and confuses entering into fuel oil and air in the mixing chamber; Fully mix again; Spray pattern with the best after stirring is burnt by the ejection of needle-valve place, thereby improves firing effect greatly, improves energy utilization rate; Energy saving, the protection environment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. valve bodies among the figure, 2. needle-valve, 3. mixing chamber, 4. oil duct, 5. air flue, 6. turbulator.
Embodiment
Like Fig. 1 is the structural representation of the utility model; A kind of efficient oil sprayer comprises valve body 1, needle-valve 2, mixing chamber 3, oil duct 4 and air flue 5, and needle-valve 2 is positioned at the top of valve body 1; Mixing chamber 3 is positioned at valve body 1 inner chamber; Oil duct 4 is positioned at valve body 1 bottom with air flue 5, all is communicated with mixing chamber 3, and the outlet port of oil duct 4 and air flue 5 respectively is provided with a turbulator 6.Turbulator 6 is the rotary blade structure, and turbulator 6 sense of rotation in oil duct 4 outlet ports are opposite with turbulator 6 sense of rotation in air flue 5 outlet ports.Mixing chamber 3 resembles a pear in shape, and lower space is big than upper space.Oil duct 4 all is an arc with air flue 5.
