- the fiber reinforced resin composition exhibits excellent thermal shock resistance, strength and the like as compared with a resin composition consisting of only the above-described resin and a resin composition containing only a resin and an elastomer.

That is, first, the rotary shaft 70 of the motor 22 is passed through the through hole of the seal member 68, and the control valve 26 is assembled to the screw exposed from the through hole via the slider 72 and the coil spring 74. Next, the motor body of the motor 22 is inserted into the first motor receiving hole 38, while the control valve 26 is inserted into the sliding hole 46 through the second motor receiving hole 44. Further, the first flange portion 36 and the second flange portion 42 are brought close to each other, and the engagement convex portion 40 is inserted into the engagement groove 52.

At this time, the end face of the first flange portion 36 is not in contact with the top surface of the step 56, and a predetermined clearance is formed between the two surfaces.
- the insulating receiving pins 80a and 80b are inserted into the insertion holes 66a and 66b, respectively, and the electrode tips 82a and 82b are inserted. That is, while the first electrode contact portion 60 is held between the reception pin 80a and the electrode tip 82a, the second electrode contact portion 62 is held between the reception pin 80b and the electrode tip 82b. In this state, the first casing 24 is relatively pressurized toward the second casing 28, and current is supplied from the electrode tip 82a to the electrode tip 82b via the wire 54.
- the wire 54 generates heat as the current is applied.
- the portions other than the first electrode contact portion 60 and the second electrode contact portion 62 at least contact the bottom wall of the engagement groove 52 and the tip wall of the engagement convex portion 40. Therefore, the heat from the wire 54 is transmitted to the wall portions of the engagement groove 52 and the engagement convex portion 40. That is, the temperatures of both the wall portions of the engagement groove 52 and the outer wall portion of the engagement convex portion 40 are increased, and the wall portions (resin composition) are softened and can flow.
- the energization of the wire 54 is stopped. Since the heat generation of the wire rod 54 is completed along with this, the softened and fluidized resin composition is cured. By this curing, the first casing 24 and the second casing 28 are joined and integrated. Thereafter, the receiving pins 80a, 80b and the electrode tips 82a, 82b are taken out from the insertion holes 66a, 66b respectively.
- the first casing 24 and the second casing 28 can be integrated without using a bolt or a mounting plate. Therefore, it is possible to reduce the number of parts constituting the flow control device 10. In addition, the troublesome work of screwing the bolt is not necessary. Moreover, the time required from the start of heat generation of the wire 54 to the end of bonding is shorter than the time required for screwing the bolt. For this reason, there is also an advantage that work efficiency is improved.
- the temperature of the wire 54 which generated heat is not uniform throughout, and becomes relatively high at the first electrode contact portion 60 and the second electrode contact portion 62, and the first electrode contact portion 60 and the second electrode contact The temperature is relatively low at a position 90 ° apart from the portion 62. That is, a temperature difference occurs in the wire 54. If a sufficient amount of heat can not be obtained at a low temperature portion of the wire 54, it is difficult to soften or flow the resin composition sufficiently at the portion, which may cause welding failure.
- the calorific value of the wire 54 may be increased so that a sufficient amount of heat can be obtained even at a low temperature portion of the wire 54.
- both the first casing 24 and the second casing 28 are made of a resin composition not containing an elastomer, there is a concern that thermal distortion may occur.
- At least one of the first casing 24 and the second casing 28 is made of a resin composition containing a thermoplastic resin and an elastomer.
- This type of resin composition exhibits excellent thermal conductivity and thermal shock resistance as compared to a resin composition not containing an elastomer. For this reason, even when the calorific value of the wire 54 is increased in order to obtain a sufficient amount of heat even at a low temperature portion of the wire 54, thermal distortion occurs in the first casing 24 or the second casing 28. Is avoided.
- the heating value of the wire 54 is increased by forming at least one of the first casing 24 or the second casing 28 from the resin composition containing a thermoplastic resin and an elastomer, It is possible to prevent thermal distortion from occurring in both casings 24 and 28. That is, since the weldable temperature of both the casings 24 and 28 can be made high, it becomes possible to avoid that a weld defect arises. As a result, sufficient air tightness can be obtained between the first casing 24 and the second casing 28.
- the control valve 26 is moved under the control of an engine control unit (ECU) (not shown) electrically connected to the power supply terminal 30 in FIG. 1. Then, the opening degree of the outlet communication passage 78 is adjusted. That is, when the throttle valve 16 is fully closed, the ECU moves the control valve 26 so that the outlet communication passage 78 has an appropriate opening degree, based on the information on the operating condition of the internal combustion engine.
- ECU engine control unit
- the ECU rotates the rotation shaft 70 by a predetermined amount, for example, in the positive rotation direction by controlling the amount of current supplied to the motor 22 through the power supply terminal 30.
- the rotational driving force at this time is converted to the driving force of the linear motion of the control valve 26 via the slider 72. Therefore, the control valve 26 in the slide hole 46 is displaced, for example, from the position shown in FIG. 1 to the outlet communication passage 78 side. At this time, the control valve 26 is in sliding contact with the inner wall of the sliding hole 46.
- the displaced control valve 26 blocks the opening of the outlet communication passage 78 to a predetermined degree.
- the opening degree of the outlet communication passage 78 is adjusted. That is, the control valve 26 controls the opening degree of the bypass passage which is a flow passage of air (intake air) which is a fluid.
- the air (intake air) introduced into the intake passage 14 enters the slide hole 46 from the bypass forward passage 18 via the inlet communication passage 76 and returns from the outlet communication passage 78 to the intake passage 14 via the bypass return passage 20.
- intake air is returned to the intake passage 14 through the inside of the flow control device 10, that is, the bypass passage.
- the intake air flowing through the bypass passage is controlled to a flow rate corresponding to the opening degree of the outlet communication passage 78.
- the ECU rotates the rotation shaft 70 of the motor 22 by a predetermined amount in, for example, the reverse rotation direction.
- the control valve 26 returns to the position shown in FIG. 1 while sliding on the inner wall of the slide hole 46.
- the opening of the outlet communication passage 78 is fully opened.
- the reinforcing fiber is not particularly limited to glass fiber, and may be carbon fiber.
- the engagement groove 52 is formed in the first flange portion 36 of the first casing 24, and the engagement convex portion 40 is provided in the second flange portion 42 of the second casing 28. Good.
