Title: Automatic liquid flow control device

Abstract: An automatically actuated liquid flow control device or valve is provided which serves to start or stop the flow of a liquid, e.g., water, through a supply line at a desired time or, in the case of stopping the flow of a liquid, after a predetermined amount of liquid has passed through the valve. The liquid flow control valve includes an expandable balloon-like bladder or reservoir. The automatic liquid flow control valve is particularly adapted for use in conjunction with lawn or garden watering systems.
