Description

[Detailed description of the invention] capreta Background of the invention This invention relates to a carburetor for an internal combustion engine, and particularly to a carburetor for controlling an air-fuel mixture within the carburetor. The present invention relates to a fuel metering device and a fuel distribution device.

A carburetor metering device maintains a constant air-fuel ratio over a wide range of throttle positions. It is adopted to hold the For example, Monosmith et al., U.S. Pat. No. 1,974,286, an air valve is connected to a fuel flow valve. Since the air flow rate increases, the total amount of fuel injected increases proportionally. will be added. However, this carburetor has no fuel in the mixing chamber of the carburetor. Since no spool valve is used to regulate fuel injection, this carburetor Unable to measure fuel accurately. In addition, the patent of Monosmith et al. is the part of the maximum air flow velocity, i.e. the narrowest part or the outlet of the mixture passage. No structure is provided to inject into the flow. Monosmith, etc., when accelerating suddenly or Incorporates a device similar to a Dalasi pot to increase the air-fuel ratio during a cold start. It is.

U.S. Pat. No. 2,236.595 to Fish discloses a fixed Throttle plate pivotally connected to the venturi area and the mixture passage of the carburetor There is a However, the fuel discharge port is located in the throttle member of the axis. Therefore, in all positions of the throttle like this invention, the most of the air-fuel mixture passage Narrow sections make it impossible for fuel to be dispersed. Furthermore, it extends to the fuel chamber. There is no fuel metering by the pivot arm attached to the throttle plate. has been done.

The diameter of the throttle plate is changed so that the passage from the throttle plate is spaced apart on the capretor wall. Since one end of the pivot arm is connected in the direction, as this pivot arm is rotated, The orifice area has been increased to allow for greater fuel flow. This way In a carburetor, the rate of fuel delivery matches the position of the throttle plate. ing. However, in this capretor, the pentine part is not fixed. (at a given throttle setting), so the airflow is responsive to engine demand. There is a drawback that there is no

Also, an adjustable fuel gauge similar to the carburetor disclosed in the Conofici patent. Capreta equipped with quantitative means, ha’? - Schmidt (Hamme r a c Disclosed in U.S. Pat. No. 3,291,464 by hm i d t) et al. There is.

Other fuel metering devices include Obermeyer, Genia (Obermeyer, Jr.) U.S. Patent No. 3,284,062 by Mick and U.S. Patent No. 3,284,062 by Mick. No. 3,342,462. Each of these fuel metering devices has an air valve. Since a link is formed between the air valve and the fuel flow control mechanism, the opening of the air valve is greatly reduced. The amount of fuel injected into the air-fuel mixture passage increases as the pressure increases.

Although each of these fuel metering devices has some advantages, each The fuel metering device provides optimal air-fuel mixture over a wide range of operating conditions. The precise fuel metering required for Unnecessary pollution and somewhat below optimal fuel efficiency. In addition, fuel injection The injection is the portion of the maximum air flow velocity over the entire throttle opening range as in this invention, i.e. It does not occur at the narrowest part or at the exit of the mixture passage.

Before attempting to solve the above-mentioned problems and providing a more precise fuel metering device, The inventor of this invention is the author of the Capt. Invents letter. This capretor is connected to the upstream portion of the mixing passage of this capretor. a pair of pliers in the rib plate and a pair of throttles in the downstream portion of this mixing passage. It has a fuel injection rod in the mixing passage between it and the plate. Axis pitch for fuel distribution The fuel is supplied to the fuel injection rod in the mixing passage by the four-wheel arm, and the fuel is supplied to the fuel injection rod in the mixing passage. Shaped to change the fuel metering interval with the metering lamp on the pivot pickup arm is moved across the fuel chamber calibrating metering lamp. rotatable venturi The plate and pickup arm are connected so that both rotate at the same time. has been done. The fuel chamber lamp is variable apart from the opening of the hinge arm. Also, the lamp in the fuel chamber allows the fuel metering interval to be varied instead of in a straight line F. The air-fuel ratio in the mixing chamber is maintained constant as it works in conjunction with the pickup arm. It is. However, it is also important to note that the fuel is It is sprayed above the Preta's throat (between the throttle plates).

This generator, unlike any of the carburetor and fuel metering devices described above, The fuel dispersion orifice chair crosses opposite the edges of a pair of throttle plates. This throttle plate is positioned like this & mixed among all throttle positions. This is the narrowest point along the Aiki Mixing Path. offers such a capreta .

This causes the fuel to always flow through the capretor at the point of maximum airflow velocity. It is ensured that the fuel is injected at the same time.

Further, the invention has a variable metering arm whose radius can be changed; The metering arm opens or closes the child valve according to the opening of the pair of pliers rib plates. , which allows fuel to pass from the fuel reservoir to the fuel distribution device. . The contour of the cam surface of the variable radius metering cam that the Dotan device contacts and presses is of the fuel metered into the fuel distribution device. The amount is obtained at each of a number of positions of the throttle where the contour of the variable radius metering cam is obtained. Optimized. Furthermore, by incorporating a valve adjustment sleeve, the The normally closed position is adjusted. This valve adjustment sleeve moves up according to the rotation of the valve closing adjustment shaft. The stationary child valve opening is thereby increased or decreased. It will be done. Such devices do not require many precision parts and can be virtually Accurate precision can be achieved.

Further, in this invention, the fuel burns only according to the initial rotation of one side of the bench rib plate. It has a unique on-off controlled flow valve that drains into the distillate. Venturi A slight initial rotation of the plate in one direction moves the on-off fuel flow control valve to the fully open position. This allows fuel to flow into the fuel reservoir.

Furthermore, according to another advantage of the invention, float valves and the like are not required. It is. This is because this device takes the advantage of fuel pressure and further improves the air-fuel mixture passage. This is because it incorporates control to disperse fuel. Even more special, for the first time The fuel that flows into the carburetor during the period enters through the pressure regulator, and this pressure regulator Maintain the feed pressure at a constant pressure of approximately 94 pounds per square inch (0.28 to 9/cm2). ing. Therefore, the fuel in this device, especially in the fuel reservoir, will be under pressure. next The fuel is metered by a fuel distribution device. This fuel dispersion device covers the carburetor chamber. It has a fuel outlet in a laterally extending flow passage. This fuel is godly has a cylindrical flow passage that determines how the air flows through the carburetor. extending radially outwardly from a flow passage extending into the air-fuel mixture passage in a direction transverse to the It has a large number of fuel distribution slits. The spool valves are distributed in this Watai passage. The amount of fuel used can be changed.

This fuel flow diaphragm responds to the volume and pressure of fuel passing through the carburetor. It's moving.

The throttle plate is placed on the side of the fuel pump, that is, at the apex facing each other on the side. The air flow rate passing through the carburetor is controlled by the air-fuel mixture passage. The maximum value is reached at the fuel injection point within the area.

Fuel distribution may be provided by a rectangular orifice, and a fuel pressure control device controls this fuel distribution. The fuel discharged from the fuel dispersion is discharged to a constant pressure. Specifically, passing through the fuel metering rod The fuel is applied to one side of the diaphragm. the other side of this diaphragm The surface has a compression spring that is applied with a predetermined force so that the flow of fuel into the distribution rod is As the volume increases, the diaphragm is forced to open the spool valve. Ru. Also, this allows more fuel to be discharged through the fuel distribution slit. Therefore, the fuel pressure will be maintained at a constant value. On the other hand, if the fuel flow is reduced , the diaphragm is biased in the opposite direction, thereby closing the fuel distribution slit. It will be done. Therefore, depending on the spool valve, the carburetor according to the present invention This makes it possible to discharge fuel more accurately.

Tests using carburetors made in accordance with this invention have shown substantially higher air-fuel ratios that can achieve performance similar to that provided by conventional carburetors. This means that fuel efficiency is greatly increased and unnecessary pollution is greatly reduced. It has been revealed.

Summary of the invention A carburetor according to the invention mixes air with fuel from a storage tank and is used in an internal combustion engine. controlled by the driver to inject a mixture of air and fuel into the intake manifold of the It responds to the throttle being controlled. This carburetor is a carburetor. and this carburetor housing has a mixture passing through the carburetor housing. air-fuel mixture passage and the air-fuel mixture that is attached to the carburetor housing within this air-fuel mixture passage. the fuel mixture extending transversely to the direction of air flow through this mixture passage. It has godliness. This fuel fraction crosses the direction of air flow where many fuel fractions discharged in the direction. In addition, a susol valve rod is installed in this fuel distribution rod to open the fuel distribution. Provided to regulate the flow of fuel through the port. Spool valve is fuel Actuated in response to changes in the metered fuel volume within the scattering rod, the fuel pressure is substantially is maintained constant. A pair of pentele plates are installed at the intake port in the air-fuel mixture passage. It is placed upstream of the nearby fuel dispenser and opens in response to the vacuum upstream of the car's throttle. The fuel discharge is regulated within the air flow. Ru. Also, the throttle valve is immediately laterally adjacent to the fuel dispenser in the air-fuel mixture passage. is pivoted to open and close, thereby allowing the fuel distribution aperture to The distance between the twin throttle valve surfaces is varied. Furthermore, this carburetor The fuel reservoir has an inlet and an outlet, and a venturi plate that is open or closed. variable the amount of outflow from the fuel reservoir to the fuel reservoir depending on the amount of opening and closing. It has a metering valve device for adjusting.

Further, according to the invention, the carburetor has an on-off flow control valve; An on-off flow control valve is connected between the fuel storage tank and the fuel reservoir and is connected between the fuel storage tank and the fuel reservoir. The opening is opened in response to the rotation of the chain rib plate. Furthermore, the fuel pressure regulator To regulate the pressure of fuel entering the capretor via an on-off flow control valve The fuel storage tank is connected between the fuel storage tank and the on-off flow control valve.

Additionally, the anticipator link can be used to reduce the air-fuel mixture when rapid acceleration is desired. A venturi plate is installed between the venturi plate and the throttle valve to make things thicker. Ru. In particular, the antisive link is connected to the throttle valve trunk plate. Because they are interconnected, sudden movement of the throttle valve will cause the venturi plate to open. This means that the opening will be performed with a much larger amount of movement. However, the slot If the torque valve is opened slowly, the anti-slip link will close to the penta-rib. No rate movement occurs. If anything, the movement of the pliers rib plate is slow. It will be subject to upstream control of the vacuum airflow of the vacuum valve.

detailed description Referring first to FIGS. 1 and 2, a carburetor 10 according to the present invention has a number of mounting options. It has a capretor housing 12 with mounting flanges 14, and these mounting flanges 14, this capretor 1o is a suction manifold (not shown) of an internal combustion engine. It is attached to.

The carburetor housing 12 has a mixing passage 16 within the carburetor housing 12. , this mixing passage 12 is first connected to the air inlet 18 at the top of the capretor 1o. , an air-fuel mixing region (throat) 20 in the center of the mixing passage 16 and a mounting flange 1 a mixture outlet 22 at the bottom of the capretor housing 12 adjacent to 4; There is.

During operation, air enters through the air inlet 18 and the air is mixed into the air-fuel mixture region. It flows into the mixing channel slag where it is atomized and vaporized in 20. This resulting air-fuel mixture The mixture is discharged from the air-fuel outlet 22, passes through the intake manifold, and then enters the interior. Leads to the cylinders of a combustion engine.

Mata, here a pair of air valves referred to as venturi plates 24.26 are empty. It is pivotally mounted within the mixing passage 16 adjacent to the air intake 018. Figures 1 and 2 Referring to related FIGS. 3A and 3B, the pentacle plate 24 is a rigid plate. The rigid plate 28 has a plurality of holes passing through the rigid plate 28. It is provided with several orifices or grooves 3o. The backfire flag 32 is a rigid plate 28 It is attached to the top side of and covers a large number of grooves 3θ. This backfire flap 32 and The rigid plate 28 is secured to the air valve shaft 34 using suitable screws or the like. It is attached to. This air valve shaft 34 is connected to the key as shown in FIG. facing the side of the carburetor housing 12 and the carburetor housing 12 It extends therethrough into the upper portion of the mixing passage 16. The air valve shaft 34 is the third A They are interlocked to rotate counterclockwise as shown in Figures and Figure 3B. Therefore, the rigid plate 28 pivots downward, thereby causing the venturi plate 24 is variably opened to allow air to flow into and pass through the mixing passage 16. similar structure A structure is formed on the pliers rib plate 26, and the venturi plate 26 is made of a rigid plate. It has a rate 38 and a flashback flash f4o attached to this rigid plate 38. , the rigid plate 38 is connected to the pair of mixing passages 16 opposite the position of the air valve shaft 34. It is attached to the air valve shaft 36 on the opposite side.

In operation, the air valve shafts 34, 36 are interlocked to rotate in opposite directions. Therefore, when one air valve shaft 34 rotates counterclockwise, the other air valve shaft 34 rotates counterclockwise. Valve shaft 36 rotates clockwise.

When a flashback occurs through the carburetor 10, the resilient flashback flap 32.4 0 causes loss to the rigid plate 28° edge plate 26 or 26 Escaped through the groove.

In addition to the venturi plates 24, 26, the capretor 10 is also pivotally mounted. A pair of throttle valves 42 and 44 are provided, and these throttle valves 42 and 44 Since they are linked to rotate with each other, the throttle valve 42 rotates counterclockwise. In this case, the throttle valve 44 rotates clockwise. These throttle valves 42.4 4 is directly interconnected to the car's throttle and is in a narrow space where the air flow rate is common. , i.e. between the ends of the throttle plate along the mixture path. Mention the location.

Referring to FIG. 4, a suitable fuel pump (not shown) pumps fuel into the storage tank. from the fuel pressure regulator 70 to the on-off operating valve 72.

This on-off operating valve 72 is activated when the venturi plate 24.26 is closed, i.e. engine is closed when stopped. However, if the throttle valve is suddenly opened or Due to the negative air pressure upstream of the throttle valve due to the operation of the internal combustion engine, the venturi plate 26. If 24 is rotated even slightly, the on-off operating valve 72 is opened. Inhabited by fuel flow.

The fuel flowing out through this 17-17 operating valve 72 flows into the fuel intake passage 74, The fuel is discharged to the fuel reservoir 76. This fuel is dispensed by the fuel distribution device 78 and becomes a fuel. from the sump 76 to a fuel distribution device 82 which provides an air-fuel mixture. Fuel is distributed at the throat of the passage 16. Extending through this fuel distribution device 82 The flow rate of fuel exiting the fuel distribution device 82 is controlled by the spool valve. .

To explain in more detail with reference to FIG. 5, one feature utilized in accordance with the present invention is The on-off operated valve 72 has a valve housing 500. 0 is a mat, that is, a spiral hole 13 in the capretor housing 12 spiraled inward. an outwardly spiraled helical first end inserted and an inwardly spiraled fuel inlet disk 50; 4. A passageway 506 extends through the valve housing 500.

When the on-off actuated valve 72 is opened, a plurality of radially extending outlets 508 are opened. Additionally, fuel is drained through passage 506 into fuel intake passage 74 .

A constriction 510 is formed in the passage 506 between the fuel inlet boss 504 and the outlet 508. A suitable ring valve 512 is provided within the passageway 506. Ru. This ring valve 512 was located in the passage 506! J, :y Kushi-#51 4, the ring seal 514 is seated against the constriction 51iy. This closes the passage 506 and blocks the outflow of fuel. This ring valve 512 is activated The actuating rod 515 is connected to one end of the rod 515, and the actuating rod 515 is connected to the carburetor housing. This actuating rod 515 is preferably This O-ring seal 516 is attached to the actuating rod. 515, so this O-ring seal 5zeVc Yes, fuel leaks into the area between the actuating rod 515 and the carburetor housing 12. I want to prevent you from doing that.

A mail bearing 51 is attached to the other end of the operating rod 515 facing the ring valve 512. 8 is attached, and this ball bearing 518 is attached to the cover of the air valve shaft 36. 520. According to a preferred embodiment, venturi plate 24 The ring valve 512 can be opened from the closed position with only a slight rotation of the ring valve 512. In other words, the cam region 520 is a half-moon having a flat cam surface 521 and a circular cam surface 522. shape, that is, a semicircular cross section. When the venturi plate is rotated to the fully closed position, ? - The bearing 518 is positioned so as to abut against one end of the flat cam surface 52. has been done. In this position, the spring 524 is against the surface of the constriction 510. to maintain ring seal 514 in the seal closed position.

When the pliers rib plate is rotated to the open position, the air valve shaft 36 is rotated as shown in FIG. By rotating the flat cam surface 521 counterclockwise as shown in FIG. The end 523 is pressed against the ball bearing 518, thereby pushing the actuating rod 5 15 is moved in the longitudinal direction of the spiral hole 13. The longitudinal direction of this operating lot 15 During the movement, the ring seal 514 is moved away from the constriction 510 and The on-off operating valve 72 is opened. Air valve shaft 36 continues to rotate when the goal bearing 518 contacts and pushes against the circular cam surface 522. However, the ring valve 512 remains in the open position without being moved. above spring 524 is compressed, so when the air valve shaft 36 is rotated clockwise. , the spring 524 causes the Cole bearing 518 to be first pressed against the circular cam surface 522. After that, the goal bearing 518 reaches the one end and this The actuating rod 515 snaps inwardly when reaching one end, and the rear The ring seal 514 does not come into contact with the surface of the constriction 510 again, and Therefore, the on-off operating valve 72 is closed. The rubber against the end of the flat cam surface 520 Due to the initial orientation of the ball bearing 520, a slight deviation of the air valve shaft 34 occurs. The actual longitudinal movement of the actuating rod 514 is limited to the rotational movement of the ring valve. 512 will be fully opened.

Referring to FIGS. 2 and 4, fuel is introduced via an on-off valve 72. It flows out into the passage 74.

This fuel intake passage 74 has an outlet within a fuel reservoir 76 . This fuel reservoir 76 is This is a chamber inside the volume valve housing 400. Furthermore, the fuel metering device 28 includes a metering cam. 402, and this metering cam 402 is fixed to a bidet shaft 404. , this pi? The cut shaft 4θ4 utilizes a suitable breath fit bearing 4θ6. It is rotatably attached to one end of the capretor housing 12. air valve shaft The upper gear attached to 34 meshes with the lower gear 410, and this lower gear 4 10 is rotatable around a fixed mounting shaft 412. One of the lower gears 410 A connecting link 414 is rotatably attached to a mounting flange 416 extending from the end. It will be done. This connecting link 414 extends from one side of the disc of metering cam 402. and are rotatably interconnected to a connecting flange 418 at a suitable location. Therefore When the air valve shaft 34 rotates counterclockwise, the upper gear 40B rotates; The lower gear 410 is rotated counterclockwise, and as a result, the connecting link 414 is rotated. is moved in the upper longitudinal direction, and the metering cam 402 is rotated clockwise as shown in FIG. It will be moved to Shi.

Due to the mutual connection between the air valve shaft 34 and the air valve shaft 36, a pliers rib 24.26 are moved relative to each other (one clockwise and the other counterclockwise) In addition, the additional connecting link 42 is connected to the preferred position of the metering cam 402 and the air valve shaft 36. and one end of a second connecting link 422 that is fixed to and rotates. Ru. Therefore, the metering cam 402 is rotated by clockwise rotation of the air valve shaft 34. When rotated counterclockwise, the additional connecting link 420 is moved to the right. As a result, the second connecting link 422 is rotated counterclockwise, and The air valve shaft 36 is thus rotated counterclockwise. upper gear 408 and the size of the lower gear 41θ, the connecting link 414, and the additional connecting link 4 The direction and size of the venturi plate 20 and the second connecting link 422 are ．． 26 rotate in opposite directions to create an opening where air flows out to the capretor. selected to allow

Metering cam 402 has a fuel metering surface 422 along its peripheral edge. This flame The metering surface 422 is a variable radius surface, which allows the metering surface 422 to have a variable radius surface. 404 The distance between the one-bit axis and any point along fuel metering surface 422 can be varied. . As will be discussed in more detail later, the fuel metering surface 422 is a cam surface, and the cam surface The metering valve is opened or closed, and the fuel is dispersed from the fuel reservoir 76. leaked into the device.

6A and 6B, the metering valve housing 400 extends through the metering valve housing 400. The metering rod 424 has a sol bearing 425, and this gall bearing 4 25 is in abutting and supporting position at one end against fuel metering surface 422. ring Seals 428 are located within one or several annular groups 429 of metering rod 424. located to form a seal between the metering valve 400 and the metering rod 424. However, this seal prevents excess fuel from leaking from the fuel reservoir 76.

The end 430 of the metering rod 424 that extends into the fuel reservoir 76 is generally concave in shape. It is. Dotan 432 has a suitable doton compression band between doton 432 and metering passage 438. The end portion 430 is fitted into a concave recess. The metering passage 438 is An outlet for fuel from the fuel reservoir 76 is provided.

According to a preferred embodiment of the invention, sleeve insertion cavity 439 includes a valve adjustment sleeve. 440 is slidably inserted. The valve adjustment sleeve 440 is inserted into the sleeve. It is a cylindrical member having an outer diameter slightly smaller than the inner diameter of the cavity 439. and is slidable between the valve adjustment sleeve 440 and the sleeve insertion cavity 439.

Additionally, the metering passage 438 extends through the valve adjustment sleeve 440 and extends through the valve adjustment sleeve 440. This sheet is tapered with a large diameter opening extending along the solid axis. The upper slope culminates inside the bottom 436 of the metering passage 438.

The spring 446 connects the bottom 436 of the metering passage and the lower surface 447 of the valve regulating sleeve 440. It is located between.

Referring to FIG. 4 in conjunction with FIGS. 6A and 6B, the valve closure adjustment arm 448 A bottle 450 passing through one end of the valve closure adjustment arm controls the metering valve housing of the fuel reservoir 76. It is pivotally mounted within the ring 4θθ. This valve closing adjustment arm 448 is a valve closing adjustment arm. has a central orifice 45 through the beam; a pair of contact protrusions 452 extending down each side of central orifice 451 such that ．． 454.

The other end of the valve closing adjustment arm has a pair of top contact protrusions 458. The protrusion 458 corresponds to a contact disc 460 fixed to the center of the valve closing adjustment shaft 462. It is supported by touching it. The valve closing adjustment shaft 462 rotates the metering valve housing 400. an adjustment end 4 extending through and through the top of the metering valve housing 400; 64 and a lower helical end 466. This lower helical end 466 is connected to the fuel portion 76. It is threaded into a helical hole 467 extending into the metering valve housing 400 at the bottom.

Since the valve closing adjustment arm 448 having the upper surface contact protrusion 458 is pushed up, The helical end 466 passes over the protruding end of the valve closure adjustment arm 448 and connects to the metering valve housing. 400.

In operation, fuel is transferred from the fuel section 76 to a plurality of metering passages 438 and valve regulating sleeves 440. through a sleeve outlet 470 into an outlet passageway 472. This exit passage 47 2 is connected to a fuel distribution device 82 as described later. This metering passage 438 The flow rate of fuel that can pass is determined by the internal surface of slave valve 1.32 and metering passage 438. 444. Therefore, the metering rod 424 is When placed in the raised position, as shown in FIG. 6B, the child valve 432 and the inner surface 4 44, the flow rate of fuel is increased from the fuel section 76 to the metering passage. 438 and is discharged through fuel outlet 472. Don't compare, When the metering rod 424 is moved downward, the child valve 432 is cylindrical and This is often moved downwardly to a position proximate to the slanted interior surface 444. This allows for flow into metering passage 438 and discharge via outlet passage 472. Fuel flow is limited.

As can be seen from FIG. 4, the vertical position of the metering rod 424 is at the fuel metering surface 4. 22, and the radius of the fuel metering surface 422 is variable. At the above point, the ball bearing 425 is in contact. Therefore, the metering cam 40 2 is in the position where it is rotated clockwise to the maximum flame of the metering cam 4θ2, the metering To prevent the rod 424 from being pushed toward the fuel section 76, the child valve 432 is connected to the child valve 432. The area of the opening between the inner surface 444 will be limited. This position is id It corresponds to ring condition or engine stop condition, which reduces fuel consumption. Only a limited flow is allowed to flow into the fuel distribution device 82. The metering cam 402 When the metering rod 424 is rotated clockwise to the maximum extreme angular position, the metering rod 424 2. Furthermore, the force of the child valve compression spring 433 acting on the metering rod 424 is In response, it will be moved upward. The position of this child valve 432 is shown in Figure 6B. It is shown.

In a specific embodiment of the invention, fuel metering surface 422 has a radius of 1 inch. The measuring rod 424 can be changed up to 2710 inches (0.5 cm), so the measuring rod 424 It will move within a range of 2/10 inches. Naturally, the identification of the fuel metering surface 422 The contour and the amount of longitudinal movement of the metering rod 424 are suitable for special vehicles. It will be understood that this may vary according to the shape of the carburetor. Various slots Engine efficiency test results obtained from a variant that changes the position of the child valve when the throttle is opened. , the specific shape of the fuel metering surface 422 is set quite optimally.

In addition to changing the shape of the fuel metering surface 422, the valve closing shaft 4 at the adjustment end 464 62, the valve adjustment sleeve 440 is inserted into the sleeve insertion cavity 439. adjusted for. Due to such rotation, the valve closing adjustment shaft 462 is connected to the metering valve housing. The valve is moved inward or outward with respect to the valve ring 400, and this movement also causes the valve to The closing adjustment arm 448 can be rotated clockwise or counterclockwise around the bin 450 as a pivot. Rotated clockwise. Referring to FIG. 6A, for example, valve closure adjustment arm 448 As the contact protrusion is rotated counterclockwise about the pin 450 that serves as a pivot, the contact protrusion Valve closure adjustment arm 448 having protrusions 452, 454 is spaced apart from annular surface 456. It will move upward. However, due to the spring 446, the valve adjusting sleeve 4 Due to the force exerted against the bottom of the valve adjustment sleeve 440, the valve adjustment sleeve 440 also It will move upwardly relative to the tube insertion cavity 439. Naturally, this is the inner surface 444 It is necessary to bring the valve close to the surface of the child valve 432, and this makes it possible to connect the child valve and the inside. The fuel flowing from the fuel section 76 into the metering passage 438 is relatively close to the surface. restricting the flow of fees.

Therefore, by rotating the valve closing adjustment shaft 462 in one direction or the other direction, the fuel A steady flow of fuel exiting the fuel section 76 into the metering passage 438 is regulated.

Referring to FIG. 4 in conjunction with FIG. 10, one embodiment of the invention includes a cold start mechanism 47. 3 is included. When the engine is cooled, this cold air starting mechanism 4 73 rotates the valve closing adjustment arm 448 about the pivot pin 450 to adjust the slave valve. 432 and the interior surface 444 to increase the opening between the fuel metering passage 438 and the interior surface 444. (Fig. 6A). Also, the engine becomes warmer after that. If the cold air start mechanism 473 It is rotated so that it returns to its normal position.

In order to incorporate such a cold start mechanism 473, a flange or other Upper projection 472 is integral with valve closure adjustment arm 448 proximate pivot pin 450 Forces formed and connected. Next, in order to expropriate this cooling start mechanism 473, An internally spiraled orifice 470 is provided through the metering valve housing 400. It is.

Referring to FIG. 10, the cold air starting mechanism 473 includes a cylinder body or housing 47 4, and (D'/!J:y) The body 474 expands when heated and contracts when cooled. Made of heat-sensitive plastic material like Delrin (trade name). . This cylinder body 474 is spirally wound outwardly at one of both ends of this cylinder body. a central passageway 4 extending through the cylindrical body 474; 78. One end of the central passageway 478 spaced from the outer helical gel is It has an inner helix 479 into which a set screw 480 is inserted. Next, rod 482 One end is attached so as to come into contact with the set screw 480 and push the set screw 480, Also, one end of this rod 482 extends into the central passageway 478 and has an outer spiral. It passes through the boss. Preferably, the rod 482 controls the expansion feature of the cylinder body 474. Tungsten rod 482 is said to not expand as much when compared to the steel. It consists of This rod 482 made of tungsten is made of plastic. spaced apart along the entire length of the cylinder body 474 from the inner surface of the cylinder body 474. Ru. Further, at a distance 484, a rod 4 made of tungsten is placed adjacent to the goth 476. 82 and a cylinder body 474 made of plastic. .

Furthermore, a heating wire is provided around the cylinder body 474 made of plastic. 486 is wound. This heating wire can be made of any of a number of well-known materials. Good too. One end of this heating wire 486 is connected to the ignition switch. Electricity flows between the heating wires whenever the ignition switch is turned on. Due to the flow, the plastic cylinder body 474 is heated.

The other end of this heating wire is grounded to the capretor body.

Referring again to FIG. 4, the outer helical boss 476 of the cold start mechanism 473 is helical. The end 4 of the rod 482 made of tungsten is inserted into the orifice 470. 85 is pressed against the flange 472.

During operation, the set screw 480 is adjusted while the engine is cooled. Therefore, the end 485 of the rod 482 made of tungsten is against the flange 422. By pressing, the valve closing adjustment arm 448 is rotated clockwise 450 times. , thereby creating an opening between the child valve 432 and the interior surface 444 of the metering passage 438. will be increased. Therefore, when the engine is cooled, fuel is drawn from the fuel reservoir 76. A large amount of fuel flows out through the dispersion device, and the fuel flows into the air-fuel mixture passage 16. A larger amount of fuel is injected, which makes the air-fuel mixture more concentrated. It turns out. However, when the ignition switch is turned on, the heating wire Starting to warm up the plastic cylinder body 474 of the cold-air starting mechanism 473 Otherwise, the plastic cylinder body 474 is expanded. this cylinder As body 474 expands, set screw 480 moves away from the body of the capretor. The end 485 of the tungsten rod 482 is moved outwardly so that the end 485 of the tungsten rod 482 is moved outwardly. 472, and the valve closing adjustment arm 448 rotates counterclockwise. is rotated in the direction of The inner surface 4 of the valve 432 and the metering passage 438 is 44 is reduced. Next, fuel is injected into the air-fuel mixture passage 16 somewhat. As a result, the air-fuel mixture will be somewhat reduced. However, at this time By now the engine has warmed up and the cold start mechanism 473 is no longer needed.

Further, referring to FIG. 8, the above-mentioned cold air starting mechanism 473 operates when the engine is cooled. automatically increases the idle ratio while the engine is warming up. It is used in place of the idling screw 724, which gradually reduces the idling speed as the speed increases. can be done. In such embodiments, the cold start mechanism 473 The rod 482 made of a tensile force is in contact with and supports the stop flange 720. It is attached to the side of the capretor.

Referring again to FIG. 2, the fuel that has passed through the metering valve device 78 enters the outlet passage 8Q. , this outlet passage 80 communicates with a fuel distribution device 82 . This fuel dispersion device 82 has a splitter 200 that controls the flow of air passing through the mixing chamber 16. It lies across the throat 20 of the mixing chamber 16 transversely to the direction of. Figure 2 Referring to FIGS. 3A and 3B together with FIG. The width across the direction of the air flow passing through the mixing chamber 16 also increases the width of the air flow passing through the mixing chamber 16. It generally has a diamond-shaped cross section with a large vertical width. Bunkeishin 200 is located in the air flow passage, so the portion of the portion 200 facing the intake air 018 is Air hitting the front surface will have an accelerated flow velocity. Because air can pass through This is because the area of the opening that passes through the opening becomes narrower.

Flow control passage 204 extends through the center of portion 200. This flow system The control passage 204 has both ends open, one end of which is connected to the outlet passage 80, and the connecting part A suitable liquid-tight seal such as an O-ring 208 is utilized. flow control circuit The other end of 204 is opened to a fuel pressure control device 84 as described below, and is connected to a suitable O-ring. The seal 208 prevents liquid leakage. This minute-keishin 200 is the minute-keishin 20. A plurality of fuel dispersion slits located at spaced apart positions along the lateral vertices 66 and 68 of It has a port 210. These fuel distribution slits 210 pass through the mixing passage 16. to discharge fuel into the throat of the air-fuel mixing passage laterally across the flow of air. It is oriented towards the sea urchin. This slit 2-0 passes through the dispersion frame 200 to control the flow. It is formed to extend until it reaches the control passage 204.

By controlling the flow of fuel through the rectangular fuel distribution slit 21o, The preferred stool is such that the fuel pressure within the control passage 204 is maintained substantially constant. A valve body is incorporated into flow control passage 204.

In particular, the stool valve body has a spool shaft 212, and the spool shaft 212 is a stool valve body. The fuel transfer passageway 214 has a central fuel transfer passageway 214 extending through the fuel shaft 212 . This suit Both ends of the roll shaft 212 are open to allow fuel to flow out. Spool shaft 21 The first end 216 of 2 is connected to the end of the outlet passage 8o for expropriating fuel from the outlet passage 80. Located adjacent. The fuel flowing out into this fuel transfer passage 214 is dispersed in a suitable manner. is transferred to the flow control circuit 204 portion of the dispersion frame 200 via the Oriswiss 21B. Ru. The dispersion orifice 218 is located at spaced apart locations along the dispersion orifice. It extends through the stool shaft 212.

Additionally, the spool shaft 212 has a number of increasing diameter regions spaced apart from each other and increasing in diameter. , these areas of increased diameter are very slightly smaller than the inner diameter of the flow control passageway 204. diameter, so that the increased diameter region 220 allows the passage through the dispersion orifice 218. Preventing fuel from flowing in the longitudinal direction along the flow control passage 204. are doing. Since the length of these cylindrical diameter-increasing regions 220 is sufficiently long, The cylindrical diameter increasing region 220 extends in the longitudinal direction so as to cover the fuel distribution slit 21o. is moved, thereby preventing the flow of fuel through the fuel distribution slit 21o. It has stopped. Furthermore, the movement of the cylindrical increased diameter region along the stool axis 212 The fuel dispersion slit is placed on the same straight line as the fuel dispersion slit. All are opened, closed, or partially opened to the same degree at the same time.

As mentioned above, the stool shaft 212 moves longitudinally within the flow control passageway 204. It is located so that

To effectuate such longitudinal movement, a suitable sleeve 222 is provided in the flow control passageway. 204 in which the sleeve 222 is abrasive. It has a polished inner surface, on which the cylindrical increasing diameter area is slanted. It will slide smoothly.

The connecting rod 224 extends into the fuel transfer passage 214. 24 is connected to the second end 202 of the fuel metering rod 21-2 using a pin 226. It is pivoted. The outer diameter of this connecting rod 224 is similar to the inner diameter of the fuel transfer passage 214. Since the fuel transfer passage 214 is also set small, the fuel in the fuel transfer passage 214 is Flow can occur between the interior surface and the connecting rod 224.

The other end of the connecting rod 22d, g) is the same as the conventional one. It is connected to the surface F of the dive flamm 23θ. Sachi, ni, this Fuel pressure: The control device '84 is connected to the housing 2. 2), this housing 2 32 is a diaphragm 230 defined in the pressure adjustment chamber 234 and the pressure adjustment chamber 236. Therefore, it is divided.

The setting screw 238 is rotated clockwise or counterclockwise to compress the spring 237. can be adjusted.

The front part of the housing 230 facing the adjustment screw 238 has an outward spiral. The disk 224 has a spiral hole under the cabbage housing 12. It is screwed together. This spiral screw 244 has an internal passage, so the fuel can be burned. The fuel can flow from the fuel transfer passage 214 into the internal passage of the helical death 244, thereby pressure is applied to the diaphragm 230.

Therefore, due to the above-mentioned spool valve body, the fuel pressure in the fuel transfer passage 214 is kept at a constant value. Maintained. By rotating the adjusting screw 238 clockwise or counterclockwise, An increase or decrease occurs in the compression of the spring against the back surface of the diaphragm 23θ. That will happen.

When in operation, an increase in the flow of fuel entering the fuel transfer passageway 214 occurs. , the diaphragm 230 is biased in the direction toward the adjustment screw 238, thus biasing the cylinder. When the diameter-increasing area is moved to the right, the fuel passes through the fuel distribution slit 2Io. It will be leaked through.

Referring to Figures 7 and 8, the relationship between the vehicle throttle and throttle valve 42.43 is shown. The connections between are shown. In particular, the vehicle throttle can be connected to suitable coupling means, e.g. The throttle link 700 is connected to This throttle link 7oθ is attached to the shaft 7θ2. , this shaft is connected to the carburetor housing 12 to which the fuel quantity device 78 is fixed. It is pivotally attached to the outside of the other end of the carburetor housing opposite to the one end. Also, this A first fan-shaped gear 704 is rotatably fixed to the shaft 702 .

This first sector gear 704 meshes with a second sector gear 706, and this second sector gear 704 meshes with a second sector gear 706. The fan-shaped gear 706 is a slot extending through the other end of the carburetor housing 2. is fixed to one end of the mounting shaft.

This antenna The other end of the anticipator 716 is connected to one end of the anticipator link 718. 9. The other end of this anti-wave link 718 is the capretor housing 12. It is secured to one end of an air valve shaft 36 which extends through the other end.

To enable quick opening of the throttle plate and the cylinder plate. (in an operating state where rapid acceleration is desired), the length b of the connecting link 714 is an anticipe. The length a of the data link 718 is also selected to be longer. In this invention, a The inticipator link 718 is set to approximately twice the length b of the connecting link 714. has been done. This will prevent the bench-lib from opening if the system throttle valve is suddenly opened. The valve is opened approximately twice as fast as the throttle valve. Naturally linked link The ratio between the length of anticipator link 214 and the length of anticipator link 218 is determined according to the spirit of the invention. It may be changed without departing from the .

Referring to FIG. 9, the anticipator 716 is connected to the silane as shown in FIG. The anticipator 716 may have a mechanism similar to that of the housing 750. A plunger 752 extends in contact with the housing 750. this The plunger 752 has a connecting shaft 754 that connects the housing 750. A seal 756 extends through one end and connects with the housing 750. The fluid 758 within the housing 750 is positioned between the shaft 754 and the shaft 754. This prevents leakage from the housing 750. The other end of this connecting shaft 754 is cylindrical. The cylindrical band 760 has a cylindrical band 760 that extends inside the housing 750 to the first part 7. 66 and a second portion 768 substantially between the two interior chambers of the housing 750. Blocking fluid flow. A one-way child valve 762 is then provided within the passageway 764. , this passageway 764 extends through the plunger 752 . this one direction Daughter valve 762 stops fluid 762 from flowing from first section 766 to second section 768. However, this one-way child valve allows the fluid 762 to flow from the second portion 768 to the housing 75θ. can flow out into a first portion 766 of the interior chamber of the cell. Therefore, plunger 752 and -Using 750 and Siranjar 752 than when pressing together with Uzing 750. 0, substantially greater tensile resistance occurs. Therefore the throttle By being moved suddenly, the Venturi plate becomes even more rapid as described above. If the venturi plate is not opened, the venturi plate will be opened and the engine will It will move in response to the vacuum created.

As shown in FIG. 8, the first sector gear 704 has a stop flag on a part of the 72o. The throttle stop bin 722 is located in the housing of the carburetor 1o. An idle screw, that is, a stop adjustment screw 7 24 is adjusted to extend through the spiral hole in this throttle stop bin 722. Possibly inserted. This throttle stop bin 722 is the capuretor housing. 12 so that the end of the stop adjustment screw 724 is located at one end of the first sector gear 70 It abuts against the stop flange 720 of No. 4.

The stop adjustment screw 724, the throttle stop bin 722 and the stop flange 720 Additionally, the closing position of the throttle valves 42 and 44 can be adjusted. So stop flange 720 and screwing the stop adjustment screw 724 into the throttle stop bin 722. The first sector gear 704 is rotated counterclockwise, which causes the slot The throttle valves 42, 44 are opened, i.e. the throttle valves 42, 44 are respectively turned clockwise. and rotated counterclockwise.

One end of the throttle spring 726 extends from one side of the second sector gear 706. It is fixed to the connecting pin 728 on the flange 730, and other than this throttle spring 726, The end is fixed to a connecting pin 732 between throttle link 708 and pivot link 710 has been done. This throttle spring 726 is in tension, so the car's throttle When the throttle force is released, the throttle valves 42, 44 return to the closed position. It turns out. Therefore, it is determined that the car's throttle is not lowered or vice versa. When not actuated, the throttle valves 42, 44 are rotated to a normally closed position. become.

operation The operation of the capretor described above is as follows.

The vehicle's throttle is first pressed to activate or increase the operating speed of the internal combustion engine. When moving the throttle so as to increase the throttle link 7 shown in FIG. 00 is rotated in the counterclockwise direction, the first sector gear 704 is rotated counterclockwise. The second sector gear 706 is rotated counterclockwise, and the second sector gear 706 is rotated counterclockwise. , the throttle valve 42 is rotated clockwise. Throttle link 708 rotates By pushing against the link 71o, the rotation link ylo and the throttle valve 42 are Rotated counterclockwise. In such a movement, the tension of the throttle spring 726 is It will be increased.

As the rotation link 710 is rotated in the counterclockwise direction, the connecting franchise 14 is 716 and the throttle is moved quite suddenly. , the antimbeta is pulled against the antimbeta link 718. This causes the anti-beta link 718 to rotate clockwise and this In particular, the venturi plate 24 is rotated downward in a clockwise direction. Fuel begins to be injected into the mixture passage and the internal combustion engine starts. On the other hand, venturi Plate 26 is powered only in response to the vacuum in the mixture passage.

Referring to FIG. 4, a number of sector gears and coupling means 408, 410, 414, 4 02, 402, 420° 422 are interconnected, so that the pliers-libre 26 is simultaneously rotated counterclockwise.

Therefore, when the throttle link 700 is rotated counterclockwise, the throttle valve 42 and 44 are each rotated from a closed position to an increasing open position, thus FIG. 3B. The throat of the air-fuel mixture passage is opened as shown in FIG. caused by an internal combustion engine The lily plate is opened in the same way by means of a partial vacuum. Therefore, the pliers rib As the rate 26 is rotated counterclockwise, the pliers rate becomes firmer. By rotating the air valve shaft 36, the cam area, that is, the flat cam surface Surface 521 (FIG. 5) pushes flat cam surface 521 against sol bearing 518. This causes the O-ring valve 512 to open.

Therefore, fuel flows out through O-ring valve 512 into passageway 506 and into the fuel intake. The fuel flows out into the passage and fills the fuel mass 76 (FIG. 4). At the same time, the air valve Depending on the amount by which the foot 34, 36 is rotated, a metering cam 402 (Fig. 4) controls the amount of fuel. The metering surface 422 is moved relative to the beer bearing 426, which causes The metering rod 424 (Fig. 6A) is gradually opened from the fully inserted position. be moved to a new position.

Therefore, the flow of fuel past the fuel metering device 78 is reduced to the point where the throttle is actuated. will be increased according to the increase in The fuel then passes through outlet passage 472 to the fuel distribution device. 82 (FIGS. 2 and 3A), and in this fuel distribution device 82, the fuel is The narrowest part of the air-fuel mixture passage through the fuel distribution slit 210 of the fuel mixture 200 It flows out into the throat. Therefore, the degree of rotation of the venturi plate 24, 26 is It is recognized that the larger the fuel will be transferred to the fuel distribution device 82.

Furthermore, the fuel that has passed through the fuel distribution slit 210 by the above-mentioned susol valve body is Provisions are made so that the amount can be precisely controlled. Therefore, the fuel distribution slit 210 is opened or closed in response to changes in the volume of fuel available to the fuel pressure control device 84. can be changed to closure.

Therefore, the fuel discharged from this fuel distribution slit 21o is always discharged at a constant pressure. It will be done. In one embodiment, the compression force of the fuel pressure control spring is between 1 and 1-lb. The preferred fuel pressure for this range is 4 pounds per square inch.

Referring again to FIG. 7, this invention utilizing anti-beta 716 An enrichment of the air-fuel mixture is obtained. Especially for short periods of time when rapid acceleration is desired. It is preferred to increase the ratio of fuel to air. Such fuel-air Mixing is performed by venturi plate 24°26 with respect to opening of throttle valve 42.44. This will be achieved by accelerating the development of Therefore, a sudden force is generated, and this force is One end of the tin beta 716 is used to pull the anti beta 716 downward. Ru. One end of the throttle dan-4716 must be attached to the yρ5 link 718. Anti-shift 1 was immediately subsequently attached to the connecting flange 714. One end of the preparatory device attached to 8 is moved upward, and this causes the pliers to be removed. The plates 24,26 are stabilized in the appropriate operating position. However, this Anne So that the timbeta 716 accelerates the rotation of the venturi plate 24°26. Since it is provided, the perpendicular air between henna z ref and f 24 + 26 A large amount of fuel can be ejected into the mixture passage without any flow. .

While variations and features of this invention have been described above, many variations and modifications can be made to this invention. Without departing from the spirit of this invention in its broadest aspects, special internal combustion engines and It will be appreciated that this can be accomplished in accordance with the Success Criteria. Therefore, the following The purpose of the following claims is to cover such modifications and variations as are within the true spirit and scope of the invention.
