Definitions

  • a float valve system 50 is positioned within housing 40 to control an amount of fluid within the chamber 16.
  • float valve system 50 includes a lower float 52, an upper float 54 and a valve assembly 56.
  • Lower float 52 is coupled to valve assembly 56 through a first actuating member 58 whereas upper float 54 is coupled to valve assembly 56 through a second actuating member 60.
  • First actuating member 58 and second actuating member 60 are spaced apart from one another in a horizontal direction.
  • Lower float 52 cooperates with valve assembly 56 to prevent fluid from entering chamber 16 when a level of liquid in the chamber 16 reaches a first predetermined level.
