a second spring that biases the control means in the suction direction; a spacer section that includes the core, the first spring, and the flow rate control means, and is provided with a fluid communication hole that faces the whole or at least the fluid introduction passage; A flow control valve characterized in that the molded spacer is molded with a fluororesin and the cylinder is integrated by attaching the molded spacer through a threaded portion or an undercut portion . The brief description of the drawing has been amended as follows. On page 10, line 20 of the specification, "7d...mold forming part" is corrected to "7b...spacer".

Claims

[Scope of utility model registration request]

An electromagnetic coil wound around a core, a flow rate control means that is attracted toward the core when the electromagnetic coil is excited and controls an opening area of a fluid introduction passage of a proportional flow control valve body, and the flow rate control means and the core. a first spring interposed between the core and the first spring that urges the flow rate control means in a direction opposite to the suction direction; a second spring that biases the flow rate adjustment means in the suction direction; A flow rate control valve comprising a spring and a cylinder containing the flow rate adjusting means and having the whole or at least a portion of the fluid communication hole facing the fluid introduction passage molded with a fluororesin.
