Abstract
A gasket includes an internal stiffener wire which maintains the semi-rigid shape of the gasket while it is in storage or during the process of its installation between two workpieces. Rigid compression limiter rings are attached to the wire by a tack weld or by semi-open loops formed in the wire. The loops mate with peripheral grooves in the rings. Each ring is secured within a side opening in each loop with a sliding or snap-fit connection. The rings may be loosely held within the loops to allow the rings to self align themselves with positioning pins provided in an injection mold which subsequently forms the gasket material around the wire and rings.
Claims6
A sealing gasket, comprising:
- a metal stiffener wire formed into a predetermined configuration;
- a plurality of rigid compression limiter members secured to said stiffener wire at spaced points therealong;
- and
- an elastomeric sealing body enveloping said stiffener wire, wherein each compression limiter member has a side surface and a peripheral groove formed in said side surface and said stiffener wire comprises an engagement section extending within said peripheral groove and wherein said stiffener wire has a resilient snap-fit connection with said peripheral groove.
A sealing gasket, comprising:
- a metal stiffener wire formed into a predetermined configuration;
- a plurality of rigid compression limiter members secured to said stiffener wire at spaced points therealong;
- and
- an elastomeric sealing body enveloping said stiffener wire wherein each compression limiter member has a side surface and a peripheral groove formed in said side surface and said stiffener wire comprises an engagement section extending within said peripheral groove, and wherein said peripheral groove in each said compression limiter member has a depth dimension slightly greater than the corresponding dimension of said wire engagement section to allow limited adjustability of said compression limiter member with respect to said stiffener wire.
A sealing gasket, comprising:
- a metal stiffener wire formed into a predetermined configuration defining a plurality of looped portions spaced along said wire;
- a plurality of rigid compression limiter rings respectively secured to said looped portions of said stiffener wire;
- each ring comprising a side surface having a peripheral groove formed therein, and each of said looped portions respectively extending within one said groove;
- and
- an elastomeric sealing body molded to said stiffener wire and to said rings.
A sealing gasket, comprising:
- a metal stiffener wire formed into a predetermined configuration;
- a plurality of rigid compression limiter members secured to said stiffener wire, said compression limiter members comprising a flanged portion having an underside;
- and
- a weld interconnecting said compression limiter members to said stiffener wires, said weld extending between said underside of said flanged portion and said stiffener wire;
- and
- an elastomeric sealing body molded to said stiffener wire.
