  • Liquid flow rate controller
    Patent number: 4648424
    Abstract: A liquid flow controller suitable for a liquid containing numerous solid particles has a casing in which a valve body is slidably accommodated. Between the inner surface of the casing and the outer surface of the valve body is provided a wide space by forming some sliding projections. Furthermore, at least one flexible closing member is provided between the casing and the valve body. This construction enables the valve body to move smoothly without jamming of the solid particles in the liquid in the space.
