Document Type and Number:
Japanese Patent JP7409928
Kind Code:
B2
Abstract:
To provide a control valve which can be entirely miniaturized by narrowing width in a direction along an axial direction of a peripheral wall of a valve body without reducing a flow rate of liquid at a seal cylinder member.SOLUTION: A control valve comprises a casing, a valve body 22, a first seal cylindrical member 37A and a second seal cylindrical member 37B. The valve body 22 is rotatably arranged inside the casing, and is provided with a first valve hole 47A and a second valve hole 47B at a position away from each other in an axial direction of a peripheral wall 44. The first seal cylindrical member is communicated with a flow outlet at one end, and is opened/closed by the first valve hole of the valve body 22 at the other end. The second seal cylindrical member is communicated with the flow outlet at one end, and is opened/closed by the second valve hole of the valve body 22 at the other end. The second seal cylindrical member has an inside passage with a cross section smaller than that of the first seal cylindrical member. An outer periphery of the second seal cylindrical member on the other end side in the axial direction is formed into an elliptical shape with a direction along an axial direction of the valve body 22 as a short axis.SELECTED DRAWING: Figure 9
