Abstract:
1. A flow control device capable of controlling the flow rate of a fluid that flows between a pair of a first port and a second port by displacement of a rod having a valve member thereon in an axial direction, comprising: a first body including a coupling having the first port and to which a tube is connected for supplying or discharging the fluid, a guide member for guiding the rod along the axial direction, and a seat on which the valve member can be seated; and a second body disposed on a lower part of the first body and having the second port to which the fluid is supplied or from which the fluid is discharged, wherein a holder is formed on an outer circumferential surface of the first body, the holder retains a check valve such that each of the check valve and a portion of the holder abuts against an inner circumferential surface of the second body, the portion of the holder abutting the inner circumferential surface of the second body is positioned below the check valve in a direction of the second port, wherein a fluid passage that communicates with the first port and through which the fluid flows is formed between the first body and the second body, wherein a first connecting member, which is disposed on an outer peripheral end of the first body, is connected to a second connecting member disposed on an end of the second body, and wherein the first connecting member and the second connecting member are positioned adjacent each other in a radial direction, which is substantially perpendicular to the axial direction.
