Kind Code:
A1
Abstract:
Provided is a flow control valve that has a simplified rattle-prevention structure, can maintain a low controlled flow rate, and can be reduced in size. This flow control valve is provided with the following: a rotor (6) that is provided around a rotating shaft (8) and, due to electromagnetic forces, rotates together with said rotating shaft (8) as a single unit; a valve element (9) that is screwed into an internal thread (93) at one end of the rotating shaft (8) and, as the rotating shaft (8) rotates, moves along the axis of the rotating shaft (8) to open and close an opening through which a fluid passes; a shaft-support member (14) that is provided at the other end of the rotating shaft (8), rotatably supports the rotating shaft (8), and restricts movement towards said other end of the rotating shaft (8); and a compression coil spring (10) that biases the valve element (9) towards the other end of the rotating shaft (8) along the axis of the rotating shaft (8).
