Abstract
A heat trap assembly for a hot water tank includes a housing and a sealing member disposed in the housing. The sealing member includes a first portion that is adapted to restrict rotational movement of the sealing member in at least two perpendicular axes. The sealing member includes a second portion that is adapted to restrict rotational movement in a third axis perpendicular to both of the at least two perpendicular axes.
Claims20
A heat trap assembly for a hot water tank comprising:
- a housing having a fluid inlet and a fluid outlet;
- and
- a sealing member disposed in said housing, wherein the sealing member includes a tail portion and a portion that is dimensioned to at least substantially cover the inlet of said housing to prevent loss of heat through the fluid inlet when no fluid is running through the inlet and allow fluid to pass around the sealing member when fluid is flowing through the outlet.
A heat trap assembly for a hot water tank comprising:
- a cage having an opening that defines a fluid outlet;
- a seat opposite to said opening that defines the fluid outlet, said seat including an opening that defines a fluid inlet;
- and
- a sealing member including a post, said sealing member trapped between the opening that defines the fluid outlet and the opening that defines the fluid inlet.
