Abstract

로터링 밸브(38) 내부에서 활류(亂流)의 발생을 억제하여 유체음을 저감하는 것을 목적으로 한다.Thereby suppressing the occurrence of turbulence in the inside of the rotor ring valve 38 and reducing fluid noise.

핸들에 의해서 회전되는 스터브 샤프트(26)와, 이 스터브 샤프트(26)에 토션바(28)을 개재하여 연결된 웜샤프트(22)와, 스터브 샤프트(26)에 끼워져 일체적으로 회전하는 밸브로터(36) 및 웜 샤프트(22)에 형성된 밸브 슬리브(32)로부터 이루어진 로터리 밸브(38)과, 상기한 밸브로터(36)에 근접한 위치에 배치되어 스터브 샤프트(26)를 자유자재로 회전하게 지지하는 베어링을 구비하고 있다. 상기한 밸브로터(36)의 베어링(30)가까이의 단부의 밸브홈(36c), (36d) 이외의 부분에 밸브로터(36)의 내외를 연통하는 관통구멍(이송통로)(36f)가 설치되어 있다. 이송통로가 밸브홈(36c), (36d) 내에 없는 것으로, 활류가 발생되지 않아서 유체음이 저감한다.A worm shaft 22 connected to the stub shaft 26 via a torsion bar 28 and a valve rotor 22 integrally rotated by being inserted into the stub shaft 26 And a valve sleeve 32 formed on the worm shaft 22. The rotary valve 38 is disposed at a position close to the valve rotor 36 and rotatably supports the stub shaft 26 And a bearing. A through hole (transfer passage) 36f for communicating the inside and the outside of the valve rotor 36 is provided at a portion of the valve rotor 36 other than the valve grooves 36c, 36d at the end near the bearing 30 . Since the conveyance passage is not in the valve grooves 36c and 36d, the flow is not generated and the fluid sound is reduced.
