Abstract:
1. A float valve system controlling an amount of liquid in a chamber, comprising: a first valve seat adapted to receive fluid from outside the chamber in a first direction through a chamber inlet; a second valve seat spaced apart from the first valve seat in a second direction, the second valve seat fluidly coupled to the first valve seat and adapted to receive fluid from the first valve seat; a first actuating member adapted to selectively open and close the first valve seat; a second actuating member spaced apart from the first actuating member in the second direction, the second actuating member adapted to selectively open and close the second valve seat; a first float coupled to the first actuating member so as to close the first valve seat upon fluid in the chamber reaching a first predetermined level; and a second float coupled to the second actuating member so as to close the second valve seat upon fluid in the chamber reaching a second predetermined level; a fluid conduit extending between the first valve seat and the second valve seat and adapted to transfer fluid from the first valve seat to the second valve seat in the second direction; wherein the fluid conduit is formed of a flexible diaphragm extending between the first valve seat and the second valve seat, the diaphragm adapted to deflect upon actuation of the first actuating member and the second actuating member.
