Mode for the Invention

[17] As shown in Figs. 1 to 3, an apparatus for reducing fuel consumption for cars according to the present invention comprises a first housing 10 formed with a fuel inlet 10a and having a hollow portion 10b, a second housing 12 formed with a fuel outlet 12a and having a hollow portion 12b, a connector 14 for connecting the first and second housings to each other and having an injection hole 14a formed at the center thereof, a first rotary fuel breaker 16 having helical grooves 16a formed longitudinally in an outer peripheral surface thereof, an accelerator 18 having an injection hole 18a formed at the center thereof, a second rotary fuel breaker 20 having helical grooves 20a formed longitudinally in an outer peripheral surface of the second rotary breaker, a rotary breaking tube 22 arranged in the hollow portion 12b of the second housing 12 and having helical protrusions 22a formed on an outer peripheral surface of the rotary breaking tube, and a stationary breaking tube 24 having linear protrusions 24a formed on an outer peripheral surface of the stationary breaking tube.

[18] The first housing 10 takes the shape of a pipe that is formed with the fuel inlet 10a of a smaller diameter facing downward and has the hollow portion 10b of a larger diameter. Threads for connection to the connector 14 are formed at a portion of an outer peripheral surface of the first housing opposite to the fuel inlet 10a.

[19] The second housing 12 takes the shape of a pipe that is formed with the fuel outlet

12a of a smaller diameter facing upward and has the hollow portion 12b of a larger diameter. Threads for connection to the connector 14 are formed at a portion of an inner peripheral surface of the second housing opposite to the fuel inlet 12a.

[20] The connector 14 takes the shape of a disk that connects the first and second housings 10 and 12 to each other and has the injection hole 14a for fuel injection formed at the center of the connector. A concave surface 14b is formed at a side of the connector corresponding to the second housing 12, so that a dispersing projection 22b of an innermost rotary breaking tube 22 among rotary breaking tubes 22, 26 and 30 and stationary breaking tubes 24, 28 and 32 arranged in a multilayered structure can be brought into close contact with the concave surface 14b so as to open and close the injection hole 14a.

[21] Here, O-rings 34 are installed at connecting portions between the first housing 10 and the connector 14 and between the second housing 12 and the connector 14.

[22] The first rotary breaker 16 is arranged within the hollow portion 10b in the vicinity of the fuel inlet 10a of the first housing 10 and has the shape of a cylinder that has the helical grooves 16a formed longitudinally in the outer peripheral surface thereof. A concave recess portion 16b is formed in a side surface of the first rotary breaker 16 facing the fuel inlet 10a, so that the introduced fuel can flow out into the helical grooves 16a. A groove 16c is formed entirely at the center of an outer peripheral surface of the first rotary breaker in a direction crossing the fuel moving direction, so that the fuel can be broken and its flow speed can be accelerated, while the fuel flowing along the helical grooves 16a produces a swirl.

[23] The accelerator 18 has the shape of a mortar-like cylinder with the injection hole

18a formed at the center thereof and is arranged in close contact between the first and second rotary breakers 16 and 20 so that the fuel broken through the first rotary breaker 16 is guided to the second rotary breaker 20 with an accelerated flow speed. Concave surfaces 18b are formed at both sides of the accelerator 18 so as to facilitate collection of the fuel directed to the injection hole 18a and injection of the fuel through the injection hole 18a.

[24] The second rotary breaker 20 takes the shape of a cylinder that is arranged within the hollow portion 10b of the first housing 10 at a side of the accelerator 18 and has the helical grooves 20a formed longitudinally in the outer peripheral surface of the second rotary breaker. A concave recess portion 20b is formed in a side surface of the second rotary breaker 20 facing the connector 14 so that the fuel, which has passed through the accelerator 18, can flow out into the injection hole 14a of the connector 14 through the helical grooves 20a. A groove 20c is formed entirely at the center of the outer peripheral surface of the second rotary breaker in a direction crossing the fuel moving direction, so that the fuel can be broken and its flow speed can be accelerated while the fuel flowing along the helical grooves 20a produces a swirl.

[25] Further, a washer 21 is arranged between the second rotary breaker 20 and the connector 14.

[26] Meanwhile, it is preferred that the helical grooves 16a and 20a of the first and second rotary breakers 16 and 20 be formed in opposite directions.

[27] In addition, it is preferred that the concave recess portions 16b and 20b of the first and second rotary breakers 16 and 20 be connected respectively to the helical grooves 16a and 20a formed in the outer peripheral surfaces of the first and second rotary breakers 16 and 20, so that the fuel can smoothly flow along the helical grooves 16a and 20a even in a state where the concave recess portions 16b and 20b are in close contact with wall surfaces of the fuel inlet 10a and the connector 4, respectively.

[28] In other words, it is preferred that the concave recess portions 16b and 20b communicate respectively with the helical grooves 16a and 20a even in a state where the first and second rotary breakers 16 and 20 are in close contact with an inner peripheral surface of the first housing 10 or a wall surface of the washer 21.

[29] The rotary breaking tube 22 takes the shape of a cylindrical tube that is arranged within the hollow portion 12b of the second housing 12, has the helical protrusions 22a formed continuously in a rotational direction on the outer peripheral surface of the rotary breaking tube, and covers the outer peripheral surface of the stationary breaking tube 24 or is covered with the stationary breaking tube 24. The rotary breaking tube 22 functions to break the fuel, while rotating about an axis due to the flow of the fuel introduced through the injection hole 14a of the connector 14.

[30] The stationary breaking tube 24 takes the shape of a cylindrical tube that is arranged within the hollow portion 12b of the second housing 12, has the plurality of linear protrusions 24a formed in a rotational direction on the outer peripheral surface of the stationary breaking tube, and covers the outer peripheral surface of the rotary breaking tube 22 or is covered with the rotary breaking tube 22. The stationary breaking tube 24 functions to cause the fuel injected through the injection hole 14a of the connector 14 to be broken, while repeatedly colliding with the linear protrusions 24a of the outer peripheral surface of the stationary breaking tube 24.

[31] Here, it is preferred that the plurality of rotary and stationary breaking tubes 22 and

24 be arranged alternately in the form of a multilayered structure to fill the hollow portion 12b of the second housing 12 therewith. In the present invention, three rotary breaking tubes 22, 26 and 30 and three stationary breaking tubes 24, 28 and 32 are arranged alternately in the form of the multilayered structure.

[32] In addition, the rotary breaking tube 22, which is the innermost rotary breaking tube among the breaking tubes with the multilayered structure and corresponds to the injection hole 14a of the connector 14, is formed with the dispersing projection 22b. The dispersing projection 22b opens or closes the injection hole 14a of the connector 14 and simultaneously disperses the injected fuel in all directions so that the fuel can be uniformly spread to the rotary breaking tubes 22, 26 and 30 and the stationary breaking tubes 24, 28 and 32.

[33] Here, it is preferred that the dispersing projection 22b of the rotary breaking tube 22 be convexly formed to disperse the fuel and the side surface of the connector 14 corresponding thereto be concavely formed.

[34] Further, a plurality of fuel vents 22c and 24b for allowing the fuel to escape toward the fuel outlet 12a are formed at portions of the outer peripheral surfaces of the rotary and stationary breaking tubes 22 and 24 in the vicinity of the fuel outlet 12a, respectively.

[35] In the apparatus for reducing fuel consumption for cars according to the present invention constructed as above, the fuel is introduced into the fuel inlet 10a of the first housing 10 and flows along the helical grooves 16a via the concave recess portion 16b of the first rotary breaker 16. Then, the fuel produces a swirl in the groove 16c of the first rotary breaker 16 and is accelerated and flows again along the helical grooves 16a. At this time, in the process where the fuel flows along the helical grooves 16a, the first rotary breaker 16 rotates and minutely breaks the fuel.

[36] In addition, the fuel that has passed through the first rotary breaker 16 is accelerated and injected to the second rotary breaker 20 through the injection hole 18a of the accelerator 18. The fuel continues to flow along the helical grooves 20a. Here, the fuel produces a swirl in the groove 20c and is then accelerated and flows again along the helical grooves 20a. Then, the fuel is guided to the injection hole 14a of the connector 14 through the concave recess portion 20b.

[37] The fuel that has reached the injection hole 14a of the connector 14 begins to be injected again to the hollow portion 12b of the second housing 12 through the injection hole 14a. Then, the fuel is dispersed in all directions while colliding with the dispersing projection 22b of the rotary breaking tube 22 arranged within the hollow portion 12b.

[38] Then, the fuel passes through the rotary breaking tubes 22, 26 and 30 and the stationary breaking tubes 24, 28 and 32 arranged in the multilayered structure. Here, the fuel flows along the rotary breaking tubes 22, 26 and 30 and the stationary breaking tubes 24, 28 and 32, thereby rotating the rotary breaking tubes 22, 26 and 30. Meanwhile, while the fuel passes through the linear protrusions 24a, 28a and 32a of the stationary breaking tubes 24, 28 and 32, the fuel pushes them upwardly. Here, the rotation of the rotary breaking tubes 22, 26 and 30 and the collision of the fuel with the linear protrusions 24a, 28a and 32a of the stationary breaking tubes 24, 28 and 32 cause the fuel to be broken again and then discharged through the fuel outlet 12a of the second housing 12 via the fuel vents 22c, 24b, 26b, 28b, 30b and 32b. Thus, the fuel that has been broken into fine particles is supplied to an engine.

[39] Further, a change in pressure occurs according to consumption of the fuel discharged through the fuel outlet 12a. When there is a change in pressure, for example, when pressure at the fuel outlet 12a is increased due to reduced consumption of the fuel, the rotary breaking tubes 22, 26 and 30 and the stationary breaking tubes 24, 28 and 32 arranged in the multilayered structure are pushed toward the connector 14 and then hermetically close the injection hole 14a of the connector 14 to shut off the inflow of the fuel. When the pressure at the fuel outlet 12a is lowered, the pressure of the injected fuel causes the breaking tubes 22, 26 and 30 and the stationary breaking tubes 24, 28 and 32 to be pushed back from the injection hole 14a of the connector 14, thereby opening the injection hole 14a and making the fuel to be supplied again.
