Abstract

Aspects of the invention are directed to condensate traps having a back portion and a front portion. The back portion includes a first passage enclosed between the first wall, a second wall, and a back wall. A first opening in the back portion connects the first wall and the second wall with a first float placed over the first opening and does not travel below the first opening and is prevented from leaving the first passage by a first constriction. The front portion of the condensate trap includes a second passage enclosed between the third wall and the fourth wall. A second opening connects the third wall and the fourth wall in the front portion and a second float is placed below the second opening such that it does not travel through the second opening and is prevented from falling below a predetermined level by a second constriction.

Dependent claims

A condensate trap comprising:

a back portion comprising a first passage enclosed between a first wall and a second wall, the back portion further comprising:
a first opening connecting the first wall and the second wall;
a first float placed over the first opening such that the first float does not travel below the first opening;
and
a first constriction above the first opening such that the float does not leave the first passage;
and
a front portion comprising a second passage enclosed between a third wall and a fourth wall, the front portion further comprising:
a second opening connecting the third wall and the fourth wall;
a second float placed below the second opening such that the second float does not travel through the second opening;
and
a second constriction below the second opening such that the second float does fall below a predetermined level;
wherein when there is a positive pressure in the condensate trap, and there is no condensate collected in the first passage, the first float is pushed by the positive pressure in the first opening.
