Claims20
A seal assembly comprising:
- a housing having an interior cavity, an outlet opening, an assembly opening, and an inlet opening, all spaced from one another;
- a working component is located in the interior cavity of the housing, the working component comprising a seal element having a body with a hollow interior and a shaft;
- and
- wherein the shaft is slidable relative to the housing to move the seal element between a compressed state and a less compressed state.
1 more element
A seal assembly comprising:
- a housing having an interior cavity, an outlet opening, an assembly opening, and an inlet opening, all spaced from one another;
- a working component is located in the interior cavity of the housing, the working component comprising a seal element having a plurality of folds, a shaft, and a locking cap that presses a tip of the seal element against the shaft;
- and
- wherein the shaft is slidable relative to the housing to move the locking cap to a blocking configuration to block the outlet opening and to move the locking cap to an unblocking configuration to not block the outlet opening.
1 more element
A method of forming a seal assembly comprising:
- placing a working component into an interior cavity of a housing, the housing comprising an outlet opening, an assembly opening, and an inlet opening, all spaced from one another;
- wherein the working component comprising a seal element having a body with a hollow interior, a shaft, and a locking cap that presses a tip of the seal element against the shaft;
- and
- arranging the shaft to be slidable relative to the housing;
- and
- wherein the shaft is configured to move a tapered seat at a tip of the shaft to a blocking configuration to block the outlet opening and to move the tip of the shaft to an unblocking configuration to not block the outlet opening.
