Abstract
A remote control assembly includes a sheath (22) having a longitudinal axis along a length thereof and defining an interior. A core element is disposed within the interior and extends along the length. A liner is disposed within the interior and coupled to the sheath (22). The liner surrounds the core element along the length. An outer layer (38) comprising a first material is coupled to the sheath (22). An intermediate layer (41) comprising a second material different from the first material is coupled to the outer layer (38). An inner layer (42) comprising a third material different from the first and second materials and is coupled to the intermediate layer (41). The second material of the intermediate layer (41) comprises an elastomeric material.
Claims17
A remote control assembly for transmitting motion along a path, said remote control assembly comprising:
- a sheath having a longitudinal axis along a length thereof and defining an interior;
- a core element disposed and moveable along said axis within said interior and extending along said length for transmitting motion along the path;
- a liner disposed within said interior and coupled to said sheath and surrounding said core element along said length while permitting movement of said core element along said axis relative to said liner, said liner including:
- an outer layer comprising a first material and coupled to said sheath,
- an intermediate layer comprising a second material different from said first material and coupled to said outer layer, and
- an inner layer comprising a third material different from said first and second materials and coupled to said intermediate layer,
- wherein said second material of said intermediate layer comprises an elastomeric material,
- wherein said inner layer defines a plurality of inner pores with said inner layer having lubricant disposed within said plurality of inner pores to lubricate said core element during movement along said axis,
- wherein said intermediate layer defines a plurality of intermediate pores with said intermediate layer having lubricant disposed within said plurality of intermediate pores with said lubricant migrating from said plurality of intermediate pores to said plurality of inner pores to lubricate said core element during movement along said axis,
- wherein said first material of said outer layer comprises nylon, and
- wherein at least a portion of said sheath is in direct contact with said outer layer;
- and
- at least one wire disposed between said sheath and said liner.
A conduit for use in a remote control assembly with the remote control assembly including a core element, said conduit comprising:
- a sheath having a longitudinal axis along a length thereof and defining an interior;
- a liner disposed within said interior and coupled to said sheath along said length, said liner including:
- an outer layer comprising a first material and coupled to said sheath,
- an intermediate layer comprising a second material different from said first material and coupled to said outer layer, and
- an inner layer comprising a third material defining a plurality of inner pores with said third material different from said first and second materials and coupled to said intermediate layer, and said inner layer having lubricant disposed within said plurality of inner pores with said lubricant migrating within said pores for lubricating the core element,
- wherein said intermediate layer defines a plurality of intermediate pores with said intermediate layer having lubricant disposed within said plurality of intermediate pores with said lubricant migrating from said plurality of intermediate pores to said plurality of inner pores for lubricating the core element,
- wherein said first material of said outer layer comprises nylon, and
- wherein at least a portion of said sheath is in direct contact with said outer layer;
- and
- at least one wire disposed between said sheath and said liner.
