This relates to an improvement of the engine control valve device which is driven and controlled by a rotary motor such as a DC motor.〇Intake air control valve for idle link rotational speed control? A method of controlling the drive using an electric motor f7L has been proposed in Japanese Patent Application Laid-Open No. 57-51934, but since the control valve is completely integrated with the electric motor, the structure is complicated and expensive.
This invention has a conical or hemispherical valve portion, a male threaded portion for rotating and moving the valve portion, and a connection that allows the valve portion to rotate fully while simultaneously being movable in the axial direction. A part is connected to this connecting part, and the electric wj machine is configured to control the movement of the valve part c9, and a female threaded part corresponding to the male threaded part is integrally formed in the engine component. F, the valve part and the motive? Separable? At the same time, we provide an engine control valve device that is easy to pack and inexpensive.Hereinafter, an embodiment of the present invention shown in Figure 1 will be explained, and Figure 1 shows the idle link of the entire engine of this invention. This is an example in which it is applied to an intake air control valve for rotational speed control. 2) branches from the intake pipe (1) upstream of the intake pipe (1), bypasses the throttle valve (2), and connects the intake pipe (1) to the intake pipe (1).
Downstream of 1), there is a bypass passage (4) which is again connected to the intake pipe il+, and there is a rotary valve '7', the tip of which is a conical valve part (5). The other end VC has a connecting part (6) for rotational driving, and a male thread part (7) on the outer periphery.
is formed. (8) The male threaded portion [7] formed in the intake pipe (1) is a female threaded portion corresponding to Vc. 191 is the opening 9tA of the bypass passage (3) [
The installed hfc is bent at the valve seat and corresponds to the valve portion (5) to determine the flow passage cross-sectional area of the bypass passage (3). It is a stepping motor as an imm machine, and has a rotor consisting of a stator coil at Q2, a bearing at (13) a rotating shaft, a bearing at 04, and a fixed permanent magnet fixed to the rotating shaft aJ at 09 (g). OQ is the motor case/). a? ) is a drive-side connecting portion that engages with the link M portion (61) and drives the rotary valve (4) by a force 2 formed at one end of the rotating shaft a3.

御用弁ｉｔを得ることができた。As described above, this invention has a conical shape (8-point hemispherical valve part (5), this 5-point hemispherical valve part (6)? a male screw part (7) for moving while rotating, and the valve part (517 rotations). In a valve device that is provided with a connecting part (6) that is movable in the axial direction at the same time as the connecting part (6) and is controlled by an electric motor +101 connected to this connecting part (6), a female thread corresponding to the 'MP threaded part (7) is provided. Part (8) Since it is formed integrally with the intake pipe 11), which is a component that is essential for the entire engine, it is possible to obtain an engine control valve IT that is simple in structure and inexpensive.
