Abstract
A valve assembly includes a tubular member, a hollow case connected to an open end of the tubular member, a linkage having a first end pivotally connected to the hollow case, a float connected to a second end of the linkage, and a control valve member movably mounted in the tubular member. A plate member is connected to the open end in the case to close the open end. The plate member has a smaller hole communicating with the open end. A narrower end of the control valve member passes through the open end and a through hole of the case, being pivotally connected to the linkage. The wider end of the control valve member is moved to close the hole of the plate member when the linkage is rotated by the float in a first direction, and to open the hole of the plate member when the linkage is rotated in an opposite second direction.
