Abstract
An engine oil system includes an oil tank and an access port cover. The oil tank includes a wall forming an internal oil cavity. The wall forms an access port extending along an access port axis through the wall. The access port cover is mounted on the wall and seals the access port. The access port cover includes a cover body and a packing ring. The cover body extends between and to an inner axial end and an outer axial end. The cover body forms a cover lip at the outer axial end. The cover lip extends circumferentially about the access port axis. The cover lip extends radially outward and axially outward, relative to the access port axis, along a lip axis to the outer axial end. The packing ring forms a fluid seal between the cover body and the wall within the access port.
Claims19
An engine oil system for an aircraft engine, the engine oil system comprising:
- an oil tank including a wall extending between and to an interior wall side and an exterior wall side, the interior wall side forming an internal oil cavity of the oil tank, the wall forming an access port extending along an access port axis through the wall from the interior wall side to the exterior wall side;
- and
- an access port cover mounted on the wall and sealing the access port, the access port cover including a cover body and a packing ring, the cover body extending between and to an inner axial end and an outer axial end, the cover body forming a cover lip at the outer axial end, the cover lip extending circumferentially about the access port axis, the cover lip extending radially outward and axially outward, relative to the access port axis, along a lip axis to the outer axial end, the outer axial end disposed radially outward of the access port and axially outward of the exterior wall side, the packing ring forming a fluid seal between the cover body and the wall within the access port;
- wherein the access port cover forms a first flange, the wall forms a second flange extending circumferentially about the access port, and the first flange is mounted on the second flange.
An engine oil system for an aircraft engine, the engine oil system comprising:
- an oil tank including a wall extending between and to an interior wall side and an exterior wall side, the interior wall side forming an internal oil cavity of the oil tank, the wall forming an access port extending along an access port axis through the wall from the interior wall side to the exterior wall side;
- and
- an access port cover mounted on the wall and sealing the access port, the access port cover including a cover body and a packing ring, the cover body extending along the access port axis between and to an inner axial end and an outer axial end, the cover body forming a cover lip at the outer axial end, the cover lip extending circumferentially about the access port axis, the cover lip extending between and to an inner radial end and an outer radial end along a lip axis, the inner radial end disposed at the access port, the outer radial end disposed at the outer axial end, the lip axis oriented at an acute lip angle relative to the access port axis, the packing ring forming a fluid seal between the cover body and the wall within the access port.
An engine oil system for an aircraft engine, the engine oil system comprising:
- an oil tank including a wall extending between and to an interior wall side and an exterior wall side, the interior wall side forming an internal oil cavity of the oil tank, the wall forming an access port extending along an access port axis through the wall from the interior wall side to the exterior wall side, the wall forming an axially-extending face circumscribing the access port;
- and
- an access port cover mounted on the wall and sealing the access port, the access port cover including a cover body and a packing ring, the cover body extending along the access port axis between and to an inner axial end and an outer axial end, the cover body having an exterior cover side extending between and to the inner axial end and the outer axial end, the cover body including an inner ring, a flange, an outer ring, and a cover lip forming the exterior cover side, the inner ring disposed at the inner axial end, the flange extending between and to the inner ring and the outer ring, the outer ring disposed at the axially-extending face, the cover lip extending axially between and to the outer ring and the outer axial end, the cover lip disposed axially outside of the access port, the outer axial end disposed radially outward of the access port, the packing ring disposed on the inner ring and forming a fluid seal between the cover body and the wall within the access port.
