  • Furnace condensate trap
    Patent number: 5704343
    Abstract: A condensate trap assembly. The assembly comprises a housing having first and second condensate inlets where the first condensate inlet is sized to pass more condensate than the second condensate inlet. The housing has an ambient air inlet providing access to an ambient air chamber within the housing, a first condensate chamber open to the first condensate inlet, and a second condensate chamber open to the second condensate inlet. The first condensate chamber, the second condensate chamber, and the ambient air chamber are open to each other and the first condensate chamber includes airflow restrictors to retard the volume of airflow through the first chamber.
