INTRODUCTION TO THE INVENTION Field of the Invention The present invention relates to an intake device for an engine, and in particular, relates to an intake passage on which a throttle valve reads a throttle valve, and is connected to a bypass passage bypassing a throttle valve. In addition, the opening and closing of the bypass valve on the side passage will connect the improvement of the actuator that opens and closes the actuator that drives it. BACKGROUND OF THE INVENTION The suction device of such an engine has already been known, for example, in Japan's real fair 6-45654. Known in the bulletin. Such an engine gas device is familiar with the fact that the throttle body forms the entire bypass passage, and because the bypass body and the actuator are installed in the throttle body, the throttle is complicated since it needs to be complicated. It is necessary to assemble all parts into the throttle body itself, and it has disadvantages such as poor combination. SUMMARY OF THE INVENTION The present invention has been achieved in view of such facts, and its purpose is to provide a good additive and assemblability, and can be miniaturized. In order to achieve the above-mentioned object, the intake device of the aforementioned engine is constructed in the present invention. The intake passage of the throttle body is connected to a bypass passage bypassing the throttle valve, and the bypass is opened and closed. The valve is connected to the actuator that drives it to open and close. In the suction device of the engine, the mounting surface of the throttle valve body parallel to each suction channel axis is connected to the mounting surface of a component and is provided on the throttle valve body. The throttle valve body communicates with the bypass inlet hole between the upstream suction channel and the aforementioned mounting surface, and the throttle valve provided through the throttle valve body communicates with the bypass outlet hole between the downstream suction channel and the aforementioned mounting surface. At the same time as connecting the aforementioned bypass inlet hole formed on the other joint surface, the upstream groove portion of the front mounting surface that locks the open surface and the original paper size standard GX297 mm formed on the aforementioned joint surface are connected. Read the precautions on the back before filling in this page)-, π-V. Description of the invention (2): At the same time that the square passes through the exit hole, the opening IW 幵 'of the opening on the installation surface is locked on the upstream side. The valve chamber outlet hole at the bottom of the groove at the downstream end of the groove part and the valve chamber groove provided in the aforementioned device component must communicate with the valve chamber inlet hole and the valve chamber outlet hole to form a bypass path, and will face the bypass valve of the valve chamber. " Actuator for opening and closing A first feature is arranged in parallel with the joint surface on the device member, and the device member is provided with a detector for detecting the opening degree of the throttle. According to the first feature, processing of the throttle body can be reduced, and The device component assembly consisting of device components, bypass valves, actuators, and flu-saving detectors can be manufactured in parallel with the throttle valve body, which helps to improve productivity. In particular, it constitutes the upstream of the main part of the bypass channel The groove part and the lower S groove: the valve chamber inlet hole and the valve chamber outlet hole can be formed at one time on the joint surface of the device component, which is extremely easy to manufacture, and because the bypass valve and the actuator become parallel to the joint surface of the split structure The upstream groove portion and the downstream groove portion, the bypass valve, and the actuator can be arranged near each other, and can be installed on a relatively thin device member. Therefore, the device member can be reduced from protruding the throttle body, and the overall size of the suction device can be reduced. In addition, the components of the device are removed by the throttle body, and the bypass passage, the bypass valve, and the flu meter can be easily rotated and maintained. Furthermore, by changing the specifications of the bypass valve and the actuator in the device components, while using the same throttle body, it is possible to simply provide suction devices for engines of different specifications, which can improve the performance of the throttle body. Mass production. Furthermore, the first feature of the present invention is that a valve duct hole parallel to the joint surface is formed in the device member, and the valve duct hole is slidably lacking a live A4 size (210X297 public copy). The paper size is applicable to Chinese national standards (CNS) 575712 A7 -------- -B7_ V. Description of the invention (3) Tusheng Zhitong valve is divided into the aforementioned valve chamber on the top side of the valve. The installation state of the flow valve body is such that the bypass valve has a slightly upward slope on the side of the actuation of the axis of the bypass valve as a second feature. According to this second feature, the installation state of the throttle body toward the engine is close to the level by the / square L valve and the actuator line, with only a slight inclination. Even when the vehicle is subjected to up and down vibration, the bypass valve and the The coupling part of the actuator does not add vertical vibration sharply, avoiding the friction caused by the vibration of the coupling part, and can stabilize the measurement performance of the bypass valve. In addition, the gradient of the bypass valve and the actuator, because the actuator is running on the upper side of the engine, even if foreign substances such as oil and water in the blow-by gas or exhaust gas recirculation (EGR) enter the intake duct, In the valve chamber of the bypass passage, such foreign matter does not enter the stepping motor side, so it can prevent the foreign matter from stagnation or the actuator from malfunctioning due to accumulation. In addition, the present invention adds a second feature. When the bypass valve is formed with an opening at the = end face to form a concave portion of the valve chamber and the bypass valve has a low degree of opening, the concave portion must communicate with the valve. A third feature is that the chamber outlet hole has a measuring notch groove extending in the axial direction of the valve. According to this third feature, in the low-opening area of the bypass valve, the bypass air intake amount can be finely adjusted by opening the area of the opening of the valve chamber toward the notch groove. Furthermore, according to the present invention, a second or third feature is added, an actuator is constituted by a stepping motor, and a bypass valve that is not rotatable in the valve duct hole is connected to its rotor through a screw mechanism as a fourth feature. μ According to the 4th special micro 'by the screw mechanism, the rotation speed of the output shaft of the stepping motor is decelerated, and the-side is transmitted to the piston-type bypass valve as the axial displacement. ^ (210X297 male J7 6

Description of the invention A central part of the invention cannot be rotatably fitted with an actuating member 32 having a threaded hole 31, and the threaded hole 31 of the actuating member 32, The screwing is integrally coupled to the threaded shaft 30 of the rotor 28a. The stator of the stepping motor 28 surveys the second accommodation hole 38 of the valve conduit hole 19 of the accommodation fixture η. The inflated portion 32a of the aforementioned recessed ceiling surface that forms abutment with the bypass valve 25 is formed at the -end of the actuating member 32, and the other end portion can lock the clip%. Between the clip 35 and the bypass valve 25, it is contracted. The coil spring 45 that imparts potential energy to move in the direction abutting on the shoulder a as described above. In this way, the bypass member 25 can be integrally connected to the operating member µ. In addition, in FIGS. 4 to 6, seal grooves surrounding the upstream groove portion 16 and the downstream groove portion 17 are formed on the joint surfaces of the device member u. When ㈣46, when the joint surface 11a overlaps the mounting center of the throttle body i, a sealing member 47 is mounted to closely contact the mounting surface 1a. In this way, the open surfaces of the groove portions M and 17 can be air-tightly closed by the mounting surface la. ^ In addition to the above-mentioned joint surface 11a and the opposite side of the device structure, there are openings of the third and fourth receiving holes 39, 40. The fourth receiving hole is a communication groove 5G and a throttle body i that pass through the device member 11. The hole σ49 communicates with the downstream side of the air intake duct 2. In addition, in the third receiving hole 39, an air temperature sensor 34 facing the sensing portion 34a is installed in the upstream groove, and in the fourth receiving hole 4 (), the rising negative pressure is formed so that the sensing portion 33a faces the communicating groove 50. Sensor%. «Through the above-mentioned flu-saving sensor 8, raise the openings of the throttle valves detected by the negative pressure sensor 33 and the air temperature sensor 34, respectively, and increase the negative pressure and air temperature Ta or by the unillustrated Information on engine operating conditions such as engine temperature Te detected by the engine cooling water temperature sensor is in-line connected to the aforementioned stepper motor. This paper size applies to China National Standard (CNS) A4 specifications (210X297 public love) (please read the back first) For the matters needing attention, please fill out this page again). 10 | Electronic control device 36 of invention description (8) 28. Therefore, the bypass valve 25 and the bumin ^ negative dust sensor and the temperature sensor 34 are installed at ::::::, = to form a device component assembly 43. Niu 1 'can be constructed Next, the function of this embodiment will be described. When the throttle valve 5 is fully closed, the opening degree of the throttle valve published by the electronic control device is 0th, which increases the negative pressure p " 刖 '[the input negative pressure Pb, the suction temperature Ta, and other related engine operating conditions. Information difference benchmark, when the engine is started: 2 = when idling, 'engine braking, etc.' must obtain the most appropriate opening degree of the bypass 阙 25 corresponding to the second turning condition, calculate the amount of power to the stepper motor 28, and implement its The rotor 28a is energized, forward or reversed. It is assumed that the forward or reverse rotation of the rotor core is transmitted to the piston-type bypass 阙 25 by the screw mechanism 27—while decelerating and deflection—as an axial direction displacement, so that the opening degree of the bypass valve 25 can be adjusted very finely. However, when the bypass valve 25 occupies a high opening position close to the stepping motor 28, the end face of the bypass valve 25 faces the valve chamber outlet hole 24 and flows through the bypass passage. The intake air intake control is larger than the opening area of the valve chamber 22 toward the valve chamber outlet hole 24, which can correspond to the engine start or first-speed idle operation. When the bypass valve 25 occupies a low opening position close to the valve to 22, since the cut groove 26 of the bypass valve 25 is wide to the outlet hole 24, the suction volume control flow through the bypass passage 1 $ is greater than that toward the cut groove 26. The opening area of the valve chamber outlet hole 24 is small and fine, which can correspond to the normal idle running or engine braking of the engine. As long as the throttle valve 5 is opened, the amount of intake air that matches the opening degree is supplied to the engine through the intake passage 2 and the engine moves to the output operation area. 11 This paper size is suitable for wealth and family (CNS) A4 specifications (⑽297). 5. Description of the invention (9) The suction suit is placed in it, and it can be detachably installed in the casing integral with the throttle body. The device component n is provided with a bypass valve 25, a stepping motor M, a coupling coil 8b, a negative pressure sensor 33 and an intake temperature sensor 34. Since the device component assembly 43 can be constituted, the number of components can be reduced. At the same time as the processing of the throttle body 丨, the throttle body 丨 and the device component combination 43 can be produced in parallel, which can improve productivity. In addition, by removing the device member U from the throttle body, maintenance of the bypass passage 15 or the on-off valve 25, the flu saver 8 and the like can be easily performed. In addition, by changing the specifications of the bypass valve 25, the stepping motor 28, and various sensor cries 8, 33, and 34 in the device member 11, it is possible to simply provide engines of different specifications while using the same throttle body i. The suction device can improve the mass productivity of the throttle body i. Because of the versatility of such a suction device, it not only expands the freedom of its layout, but also improves mass productivity and reduces costs. Furthermore, the upstream groove portion 16, the downstream groove portion 17, the valve chamber inlet hole 23 and the valve chamber outlet hole 24 of the main part of the component bypass passage 15 are formed on the joint surface 11a of the device member η in one stroke, which is extremely easy to manufacture. Communication valve: The valve duct hole 19 between the inlet hole 23 and the valve chamber outlet hole 24 is arranged in parallel with the joint surface 11a of the device member. The upstream groove portion 16 and the downstream groove portion 17 and the valve guide hole 19 are arranged close to each other. Since it is formed in a relatively thin device member, it is possible to reduce the device member 11 from protruding out of the throttle body 丨, and it is possible to miniaturize the entire suction device. Furthermore, in the state where the throttle body 丨 is installed on the engine E of the motorcycle, the bypass valve 25 and the stepper motor 28 connected by the screw mechanism 27 have only a slight inclination Θ close to the level. The connection part of the vibration, the bypass valve 25 and the stepping motor 28, that is, there is no sharp up and down vibration 575712, the description of the invention (10) acts on the screw mechanism 27 to avoid the friction caused by the vibration of the mechanism 27, and can be bypassed The metering performance of the valve 25 is stabilized. In addition, the inclination of the bypass valve 25 and the stepping motor 28 is 0. Since the stepping motor 28 is located on the upper side, even when the engine is running, fluid foreign objects such as oil and water in blow-by gas or exhaust gas recirculation (EGR) The suction chamber 2 penetrates into the valve chamber 22 of the bypass passage b, and such foreign matter does not enter the stepping motor paste. Therefore, it can prevent the stepping motor 28 from malfunctioning due to freezing or accumulation of the foreign matter. The invention is not limited to the above. Various designs can be changed in the embodiments without departing from the scope of the gist.
