Patent ID: 6944890

Claim:
A hydraulic time release system for regulating the flow of liquid therethrough, comprising: a timer body having a timer inlet for providing liquid to the timer body at a timer inlet flow rate and a timer outlet for discharging liquid from the timer body at a timer outlet flow rate, the timer body including a plurality of reservoirs being in at least partial fluid communication with one another; wherein: one of the reservoirs includes a drain tube disposed therewithin and having a lower end and an upper rim, the lower end opening to an exterior of the timer body, the upper rim being generally positioned under the timer inlet in spaced relation thereto; and a timer float assembly disposed within one of the reservoirs and being operatively connected to a float valve configured to be moveable between open and closed positions in response to variations in the reservoir liquid level corresponding to the flow of liquid thereinto; wherein: the movement of the float valve to the open position results in a substantial portion of liquid entering the timer body at the timer inlet to pass through the drain tube and exit the timer body with a remaining portion of the liquid successively flowing to the reservoirs during which time the liquid exits the timer outlet at a flow rate that is substantially less than the timer inlet flow rate; and the movement of the float valve to the closed position resulting in the float valve blocking the flow of liquid into the drain tube causing the liquid to fill the timer body whereupon the timer outlet flow rate is substantially equivalent to the timer inlet flow rate.
