<p>PROBLEM TO BE SOLVED: To provide desired flow characteristics to a fluid flow control device at low cost by including a main body with end face, a passage extending from the end face to the inside of the main body, peripheral surfaces, and multiple passages extending from the passage approximately radially to the peripheral surfaces. SOLUTION: A housing is provided with an annular stepped part which supports a flow control or flow limiting device 17 arranged, in the form of insert, in the center passage in longitudinal direction. Also the main body 21 of the insert 17 is provided with an end part disk part 18 which is provided with a roughly flat end face 19, and a passage 20 extending from the end face 19 to the inside of the main body 21 terminates at the inside of the main body 21. Then a passage 22 extending from the passage 20 radially terminates at an opening 24 which is formed on the peripheral surface 23. Thus water under pressure which is fed to the end face 19 flows along the passage 20, passes through the passage 22, and changes its flow direction to a radial direction, and the jet flow of water comes from the insert 17 through the opening 24.</p> |
