Title (EN) ROTARY CONTROL VALVE
(FR) SOUPAPE DE COMMANDE ROTATIVE
(JA) 回転式制御弁
Abstract:
(EN) A contact surface at the front end of a seal member (18), the contact surface being in sliding contact with the outer peripheral wall (20) of the circular cylinder section of a rotor (14), is formed as a circular arc-shaped curved surface conforming to the shape of the outer peripheral wall (20) of the circular cylinder section. Further, ridges (44A, 44R) are formed at at least the front end or the rear end of the circular arc-shaped curved surface when viewed in the rotational direction of the rotor (14), the ridges (44A, 44R) being formed by non-contact sections (43) which are not in contact with the outer peripheral wall (20) of the circular cylinder section. An urging member (19) for pressing the contact surface of the seal member (18) against the outer peripheral wall (20) of the circular cylinder section is disposed on the opposite side of the contact surface of the seal member (18). This configuration enables the contact surface at the front end of the seal member (18) and the outer peripheral wall (20) of the rotor (14) to be in appropriate sliding contact with each other.
(FR) La présente invention concerne une surface de contact au niveau de l'extrémité avant d'un élément d'étanchéité (18), la surface de contact étant en contact coulissant avec la paroi périphérique externe (20) de la section de cylindre circulaire d'un rotor (14), est formée sous la forme d'une surface incurvée en forme d'arc circulaire se conformant à la forme de la paroi périphérique externe (20) de la section de cylindre circulaire. En outre, des crêtes (44A, 44R) sont formées au niveau d'au moins l'extrémité avant ou l'extrémité arrière de la surface incurvée en forme d'arc circulaire lorsqu'elle est vue suivant la direction de rotation du rotor (14), les crêtes (44A, 44R) étant formées par des sections sans contact (43) qui ne sont pas en contact avec la paroi périphérique externe (20) de la section de cylindre circulaire. Un élément de poussée (19) pour presser la surface de contact de l'élément d'étanchéité (18) contre la paroi périphérique externe (20) de la section de cylindre circulaire est disposé sur le côté opposé de la surface de contact de l'élément d'étanchéité (18). Cette configuration permet à la surface de contact au niveau de l'extrémité avant de l'élément d'étanchéité (18) et la paroi périphérique externe (20) du rotor d'être en contact coulissant approprié l'une avec l'autre.
(JA) ロータ(14)の円筒部の外周壁部(20)と摺接するシール部材(18)の先端の当接面が、円筒部の外周壁部(20)に沿った円弧状曲面に形成され、更にロータ(14)の回転方向で見て円弧状曲面の少なくとも前側端、或いは後側端に、円筒部の外周壁部(20)と非接触となる非接触部(43)によって稜線部(44A、44R)が形成されている共に、シール部材(18)の当接面を円筒部の外周壁部(20)に押し付ける付勢部材(19)がシール部材(18)の当接面の反対側に配置されている。かかる構成により、シール部材(18)の先端の当接面とロータ(14)の外周壁部(20)とを適切に摺接させることができる。
