摘要： PURPOSE:To provide a small regulating valve which regulates opening with high accuracy, by a method wherein a cylindrical valve body the end part of which is inclined is rotatably disposed along a sideways opening formed in a housing. CONSTITUTION:A cylindrical valve body 14 is disposed between a first through- hole 11 on the upper stream side and a second through-hole 12 on the downstream side so that it is rotatable in a range of 180 deg.. The end of the valve body 14 is formed in a slope formed such that a height (l) exceeds an opening diameter (d) of the second through-hole 12. By rotating the valve body 14 in a range of a 180 deg., the opening end of the through-hole 12 is arbitrarily regulated between full opening and full closing. This constitution enables fine and high- precise regulation of the opening of the aperture at a rotation angle of as high as 180 deg.. Further, the valve is easily mounted even in a limited space spot.
