An elliptic plate-shaped valve attached to a portion located in the fluid passage by a screw or the like, and a stud bolt provided on an outer surface of the body.

Then, it is attached between the intake manifold and the cylinder block via stud bolts, one end of the shaft is connected to the actuator, and when the actuator is actuated, the valve rotates through the shaft and the peripheral portion of the valve becomes fluid. The fluid passage is closed by contacting the inner wall of the passage, or the valve is opened in parallel with the flow direction of the fluid passage.

However, in the conventional intake control valve configured as described above, since the whole is formed of a rigid body such as an aluminum casting, vibration and heat from the cylinder block side of the engine are transferred from the stud bolt to the body. Or the abnormal noise generated when the valve is operated is transmitted to the intake manifold side. For this reason, these vibrations, abnormal noise, heat, and the like are transmitted to the inside of the vehicle through the intique manifold, which gives a driver an uncomfortable feeling.

This invention solves the above-mentioned problems of the prior art, and completely absorbs vibration and heat from the cylinder block side of the engine, and also completely absorbs abnormal noise generated during valve operation. It is an object of the present invention to provide an intake control valve that can completely prevent vibration, abnormal noise, heat, and the like from being transmitted to the intake manifold side, and can obtain comfortable driving performance.

Hereinafter, an embodiment of the present invention shown in the drawings will be described.

1 and 2 show a first embodiment of an intake control valve according to the present invention. The intake control valve has a body 11 made of a rubber material provided with a circular fluid passage 12.
A shaft 13 rotatably provided in the body 11 so as to penetrate the fluid passage 12; an oval plate-shaped valve 14 attached to a portion of the shaft 13 located in the fluid passage 12 by a screw 15; Stud bolt provided on the outer surface of
A mounting plate 16 is provided with a mounting plate 17 integrally formed by welding or the like.

In this case, the shaft 13 on the inner surface of the fluid passage 12 of the body 11
A bearing 19 for rotatably supporting the shaft 13 is integrally provided at a portion through which is inserted by insert molding. The body 11 and the mounting plate 16 are integrally connected by vulcanization bonding or simultaneous molding. Further, an actuator (not shown) is connected to a portion of the shaft 13 protruding from the body 11.

Then, the intake control valve configured as described above is mounted between the cylinder block (not shown) of the engine and the intake manifold via the stud bolt 17, and when the engine is operated, the vibration and heat of the engine are transmitted through the cylinder block. The vibration and the heat are transmitted to the mounting plate 16 of the intake control valve, and the vibration and heat are absorbed by the body 11 made of rubber material located inside the mounting plate 16.

Therefore, the vibration and heat from the engine are not directly transmitted to the shaft 13, so that the shaft 13 can be smoothly rotated even when the engine is operating, and the vibration from the engine is transmitted through the intake manifold. To the vehicle body.

In this case, a mounting plate 16 is provided between the body 11 made of rubber and the cylinder block or the intake manifold.
, The body 11 is uniformly compressed over the entire body during installation.

Therefore, the compressive stress of the body 11 does not become partially uneven and does not hinder the smooth operation of the shaft 13, and the valve 14 attached to the shaft 13 can be operated stably. Performance can be obtained.

Then, by operating an actuator (not shown),
Even if the fluid passage 12 is opened and closed by rotating the valve 14 integrally with the shaft 13, the peripheral edge of the valve 14 comes into contact with the body 11 made of a rubber material, so abnormal noise is generated when the valve 14 is opened and closed. There is no such a case, and abnormal noise at the time of valve operation is not transmitted to the inside of the vehicle through the intique manifold.

FIG. 3 shows a second embodiment of the intake control valve according to the present invention, in which a bearing 30 is provided by insert molding over the entire portion of the body 21 where the shaft 23 contacts. The other configuration is the first configuration.
Has the same configuration as that shown in the embodiment.

That is, the intake control valve shown in this embodiment includes a body 21 made of a rubber material provided with a circular fluid passage 22 and a shaft 23 rotatably provided on the body 21 so as to pass through the fluid passage 22. An elliptical valve (not shown) attached to a portion of the shaft 23 located in the fluid passage 22 by a screw (not shown) and a stud bolt 27 provided on the outer surface of the body 21 are integrally formed by welding or the like. And an attached mounting plate 26.

In this case, a bearing 30 for rotatably supporting the shaft 23 is integrally provided at a portion of the body 21 where the shaft 23 contacts, by insert molding. The body 21 and the mounting plate 26 are integrally connected by vulcanization bonding or simultaneous molding. Further, an actuator (not shown) is connected to a portion of the shaft 23 projecting from the body 21.

Also, in the intake control valve shown in this embodiment, when the engine is operated, the vibration and heat of the engine are attached to the intake control valve via the cylinder block in the same manner as in the first embodiment. The vibration and the heat are transmitted to the plate 26 and are absorbed by the rubber body 21 located inside the mounting plate 26.

Therefore, the vibration and heat from the engine are not directly transmitted to the shaft 23, and the shaft 23 can be smoothly rotated even during the operation of the engine, and the vibration from the engine is transmitted through the intake manifold. To the vehicle body.

In this case, a mounting plate 26 is provided between the body 21 made of rubber and the cylinder block or the intake manifold.
, The body 21 is uniformly compressed throughout.

Therefore, the compressive stress of the body 21 does not become partially uneven and does not hinder the smooth operation of the shaft 23, and the valve attached to the shaft 23 can be stably opened and closed, and Performance will be obtained.

Then, by operating an actuator (not shown),
Even if the fluid passage 22 is opened and closed by rotating the valve integrally with the shaft 23, the peripheral edge of the valve comes into contact with the body 21 made of a rubber material. No abnormal noise during valve operation is transmitted to the interior of the vehicle via the intake manifold.

When the intake control valve shown in each of the above embodiments is mounted between the cylinder block and the intake manifold, rubber materials are provided between the cylinder block and the mounting plate, and between the intake manifold and the mounting plate. Thus, the absorbency against vibration, heat, and the like may be further improved.

[Effects of the Invention] With the structure of the invention described above, vibration and heat from the engine are absorbed by the body made of rubber material inside the mounting plate. Does not directly transmit to the shaft that rotates the valve. Therefore, the shaft can be smoothly rotated, the valve attached to the shaft can be smoothly operated, and stable performance can be obtained. Further, since the vibration from the engine and the abnormal noise at the time of operating the valve are not transmitted to the vehicle body via the intake manifold, comfortable driving performance can be obtained. Furthermore, since the mounting plate is interposed between the body made of rubber and the cylinder block or the intake manifold, the body made of rubber can be uniformly compressed over the entire body at the time of mounting. Therefore, the compressive stress acting on the body made of the rubber material does not become partially uneven and hinders the smooth operation of the shaft, and the valve attached to the shaft can be opened and closed stably. Thus, stable performance can be obtained in the long term. And since the valve comes into contact with the body made of rubber material when opening and closing, no abnormal noise is generated when opening and closing the valve, and the abnormal noise when opening and closing the valve is transmitted to the vehicle body via the intake manifold. The driving force is not transmitted to the vehicle, and excellent effects such as comfortable driving performance can be obtained.
