Abstract
A two-way flow control valve for repeatedly dispensing a limited amount of liquid. A float valve is linked to a second valve and storage chamber such that one valve is closed when the other is opened, and vice versa. The chamber fills when the float valve is closed, and empties when the float valve is opened. The assembly is useful for dispensing a liquid cleaner into a toilet tank.
