Abstract
A method and apparatus for reinforcing a tubular-shaped sealing collar, extending from a filter cartridge are provided, by embedding, or substantially encapsulating, a reinforcement element within the tubular-shaped sealing collar, for resisting a change in circumference of at least a portion of the tubular-shaped collar. The collar may be formed from a resiliently compressible foam material, and the reinforcement element may be formed from a substantially non-compressible material.
Claims25
A method for reinforcing a tubular-shaped sealing collar, extending from a filter cartridge about an axis of attachment of the filter cartridge, and having a body of resilient material defining a circumference of the collar about the axis of attachment, the method comprising, embedding a reinforcement element within the tubular shaped sealing collar, for resisting a change in the circumference of at least a portion of the tubular shaped collar about the axis of attachment.
A filter apparatus, comprising:
- a filter cartridge, defining an axis of attachment of the filter cartridge, and including a filter element, and a tubular-shaped sealing collar, extending from the filter cartridge about the axis of attachment of the filter cartridge;
- the tubular-shaped sealing collar having a body of resilient material defining a circumference of the collar about the axis of attachment;
- the tubular-shaped sealing collar also having a reinforcement element embedded within the body of tubular shaped sealing collar, for resisting a change in the circumference of at least a portion of the tubular shaped collar about the axis of attachment.
A filter cartridge, defining an axis of insertion of the filter cartridge, and including a filter element, and a tubular-shaped sealing collar extending axially from the filter element about the axis of insertion of the filter cartridge;
- the tubular-shaped sealing collar having a body of resilient material defining a circumference of the collar about the axis of insertion;
- the tubular-shaped sealing collar also having a reinforcement element in the form of a substantially tubular-shaped ring embedded within the body of tubular shaped sealing collar, for resisting a change in the circumference of at least a portion of the tubular shaped collar about the axis of insertion.
