PURPOSE:To provide a compact and durable control valve by providing a plurality of holes in the wall of an inner body within a valve chamber and fitting a flexible pipe onto the outer periphery of the inner body to cover the holes. CONSTITUTION:When the outlet 9 side has a desired liquid level, a float 21 floats up to push up a lever 20 which pushes up a valve body 17 and close a through hole 16 to choke a second path. Into a pressure chamber 10 is introduced continuously liquid at the inlet 3 side through a thin hole 15 in a first path so that the pressure is raised to provide the same as that at the inlet 8 side. A flexible pipe 4 is pressed closely aganst seal surfaces A, B by its elastic force and differential pressure between the pressure chamber 10 and outlet 9 side so that an inlet path 8' and an outlet path 9 are shut off to stop the supply of liquid. Thus, a compact and durable control valve is provided. |
