Float controlled condensate discharge device

A float controllable condensate discharge device responsive to a level of condensate comprising;

• a housing having an input supply opening, a discharge opening, and a flow chamber communicative with said input supply opening;
• a walled interior chamber formed within said flow chamber;
• a valve seat defining the opening of said discharge opening within said interior chamber;
• a closure element cooperating with said valve seat and movable between an opened and closed position relative thereto, wherein in the closed position, said element rests on said valve seat in sealing relationship,
• a float disposed in said internal flow chamber and movable along a stroke distance within said interior chamber,
• lever means coupling said float with said closure element and having a force transmission ratio applied to said closing element that is proportional to the stroke distance of said float, said interior chamber operating as a condensate throughput chamber with said float dividing said interior chamber into upper and lower zones and defining therebetween, a throttle aperture communicating with said zones and formed along the periphery of said float, and the wall of said interior chamber;
• said interior chamber having inflow opening means communicative with the inlet opening in said flow chamber for receiving the condensate to be discharged, said inflow opening means being formed upstream of said throttle aperture, said valve seat and said closure element being disposed in said interior chamber downstream of said throttle aperture so when the condensate fills said interior chamber to a predetermined level, said float will move downstream into the upper zone of said interior chamber and raise said closing element off said valve seat to permit the condensate to be drained through said throttle aperture into the discharge opening of said housing.
