<p>A flow controller is provided to freely control a flow amount of a controlled flow and reduce weight or material costs at the same time. A flow controller(S1) includes a cylindrical body(2) and a cylindrical knob(4). The cylindrical knob covers parts of an outer peripheral surface of the body. First and second nipple members(6,8) are attached to both ends of the cylindrical body. A first port(6a) is formed on the first nipple member. A second port(8a) is formed on the second nipple member. The first and second ports are installed at both ends of the cylindrical body to bring into contact with the passages of fluid. The cylindrical body has a first flow passage connected to the first port and a second flow passage connected to the second port. A check valve suppresses the flow of the fluid toward a first channel from a second channel through a fourth channel as well as allows the flow of the fluid toward the second channel from the first channel through the fourth channel.</p> |
