ABSTRACT:
A flow regulator comprises a float valve body provided in an inner container which in turn is fitted in a lower portion of an outer container. The float body has an elongated slender upper portion which is suddenly restricted at an upper side and an elongated tapered lower portion. The slender upper portion extends through a central opening of a first plate at the top end of the inner container. The tapered lower portion passes through a valve seat of a second plate placed below the first plate and extends beyond a restricted tubular bottom end of the inner container. A flexible tube is sleeved on said tubular bottom end and receives the end of the float body. By moving the flexible tube, the float body can be moved away from the valve seat. A further valve seat may be formed in the tubular bottom end of the inner container.
