Patent ID: 8882473

Claim:
A liquid dispensing mechanism capable of achieving an increased inflow and an increased outflow rate, the mechanism comprising an inlet line configured to receive liquid from an external reservoir, and further configured to release a liquid via an outlet line, said mechanism comprising: a pressure chamber configured to store liquid and provide a liquid level configured to fall or rise as a function of pressure; a plurality of pressurizing ports arranged to provide pressurizing media to the pressure chamber and a plurality of depressurizing ports arranged to release pressurizing media from the pressure chamber; a float member in said pressure chamber configured to sense the liquid level in the pressure chamber as a function of a position of said float member; a multiple valve actuator assembly comprising a plurality of pressurizing valves for opening and closing the pressurizing ports and a plurality of depressurizing valves for opening and closing the depressurizing ports, wherein the multiple valve actuator assembly comprises a delay providing arrangement configured to provide a time-delay between at least one of: (a) engaging subsequent depressurization valves; and disengaging subsequent pressurization valves; or (b) engaging subsequent depressurization valves; and disengaging subsequent depressurization valves; and a snap action valve actuating mechanism comprising fastener elements configured to actuate said multiple valve actuator assembly in correlation with position of said float member.
