SEALED FILL CAP ASSEMBLY
First Claim
1. A fill cap assembly for a vehicular transmission, the fill cap assembly comprising:
- a fill part forming a cavity therein, the fill part having a fill part edge;
a channel portion forming a channel formed in the fill part, the channel configured to fluidly connect the cavity of the fill part to an inner space within the vehicular transmission; and
a flexible membrane disposed adjacent to the fill part edge, the flexible membrane being connected to the fill part edge to form a seal along the fill part edge, the flexible membrane being configured to expand when pressure rises within the cavity.

Abstract
A fill cap assembly for a transmission is provided. In one form, the fill cap assembly includes a first part and a second part, each defining a cavity therein. A flexible membrane is disposed between the first and second parts and separates the cavities of the first and second parts. The cavities are sealed from each other by the membrane. The cavity of the first part is configured to be in fluid communication with the inside of the transmission. When pressure rises in the transmission, the flexible membrane expands into the cavity of the second part. When pressure sinks in the transmission, the membrane collapses partially into the cavity of the first part, thus expanding out of and/or away from the cavity of the second part.

20. A fill cap assembly for a vehicular transmission, the fill cap assembly comprising:
-
a first sphere half forming a first cavity therein, the first sphere half defining a round first edge; a projection extending from a side wall of the first sphere half, the projection defining a channel therein, the channel being in fluid communication with the first cavity, the channel being configured to fluidly connect the first cavity to an inner space within the vehicular transmission; a second sphere half forming a second cavity therein, the second sphere half defining a round second edge, the round second edge being connected to the round first edge; an elastomeric membrane disposed between the first and second sphere halves adjacent to the first and second round edges, the elastomeric membrane forming a seal between the first and second cavities, the first and second cavities not being in fluid communication with each other, the elastomeric membrane being configured to expand when pressure rises within the first cavity.
