ABSTRACT:
A condensate trap for an air conditioning system includes a chamber having an upstream port coupled to the air conditioning system and a downstream port coupled to the external atmosphere, a sealing device disposed in the chamber, a lower seat member positioned in the chamber, and an upper seat member, disposed between the sealing device and upstream port. In response to a positive pressure at the upstream port, the sealing device contacts the lower seat member to prevent air from the air conditioning system from exiting to the external atmosphere. On the other hand, in response to a negative pressure at the upstream port, the sealing device contacts the upper seat member to form a seal which prevents the ingress of air from the external atmosphere into the air conditioning system. Moreover, in response to a predetermined amount of condensate accumulating in the chamber, the sealing device moves out of contact with the seat members to allow the fluid to drain from the downstream port of the chamber.
