Liquid dispenser

摘要

A liquid dispensing mechanism adapted to achieve an increased inflow and an increased outflow rate and consisting of an inlet line adapted to receive liquid from an external reservoir, and adapted to release aid liquid via an outlet line, said mechanism comprising a pressure chamber adapted to store liquid and provide liquid level to fall or rise as a function of pressure, before release; a buffer chamber adapted to connect with said pressure chamber by means of non-return valves, and further adapted to store liquid before it flows into said pressure chamber, in order to increase flow coefficient of inlet line; float member in said pressure chamber, adapted to sense level of liquid in said pressure chamber by means of position of said float member; multiple valve actuator assembly adapted to actuate a pre-defined configuration of valves, with a time-delay between engaging or disengaging subsequent valves, for controlled engaging or disengaging pressure in a predetermined format; snap action valve actuating mechanism comprising fastener elements adapted to actuate said multiple valve actuator assembly in correlation with position of said float member.

1. 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; anddisengaging subsequent pressurization valves; or(b) engaging subsequent depressurization valves; anddisengaging 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.
