  • Patent number: 8882473
    Abstract: 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 me

  • Publication number: 20130008531
    Abstract: The present invention provides a pressure reducing valve. The pressure reduction valve includes a main body, an inlet, an outlet, a stem, a main seat, a pilot diaphragm, a main head, and a control spring. The pressure reduction valve includes additional auxiliary seats with corresponding auxiliary heads and displacement members/surfaces. The pressure reduction valve additional includes auxiliary seats with corresponding auxiliary heads and displacement members/surfaces enables stage wise opening of the secondary seats and the main seat. This enables to meet highly varying media flow demands using single pressure reduction valve, having less hunting effect and eliminating use of multiple pressure reduction valves.
