Check valve and trap assembly
First Claim
1. A combination one way check valve and fluid trap device for use with fluid drain systems used to remove condensate moisture from apparati such as air conditioners, coolers and ice makers, the device comprising a float housing directly connected to a generally U-shaped fluid trap, said float housing containing a ball float positioned on a float seat, a float seal contained within said float seat, said float seal comprising an O-ring, said fluid trap comprising an inflow conduit segment having an inflow opening for connection to the outflow opening of a fluid drain system, an outflow conduit segment connected to said inflow conduit segment, said outflow conduit segment having an outflow outlet connected to said float seat, whereby said ball float is sealingly seated only on said float seal within said float seat unless water flows through said fluid trap, such that no water or gas can enter said fluid trap through said outflow opening.

Abstract
A combination check valve and fluid trap device for connection to the outflow aperture of a condensate moisture drain system on an air conditioner, ice maker, cooler or like apparatus, the device comprising a ball float sealingly seated on a float seat within a housing, the float seat being connected to the outflow conduit of a generally U-shaped fluid trap having an inflow conduit for connection to the drain system, whereby water and gas are prevented from entering the fluid trap through the outflow conduit but excess water will move the ball float from the float seat to allow water to flow out of the outflow conduit. Preferably the fluid trap is provided with rotation means whereby the longitudinal axis of the inflow conduit can be adjusted relative to the longitudinal axis of the outflow conduit so that the two axes are not aligned in parallel.
