A multi-layer gasket including first and second functional layers, each having an opening. Each of the functional layers includes a compression bead, and the compression beads contact and seal against one another when the gasket is compressed between a cylinder head and an engine block. At least one of the functional layers includes a stopper disposed between the compression bead and the opening. The stopper has a gear-like shape including a plurality of circumferentially spaced teeth. Each tooth extends upwardly from a plane by a distance which is less than the combined height of the compression beads. When the gasket is compressed between the cylinder head and engine block, the stopper ensures that the compression beads remain elastically biased against one another and maintain a gas-tight seal.

Gasket with a compression limiter

A spiral wound gasket () is disposed between joint members () of a hot fluid joint to seal a gap () therebetween. The spiral wound gasket () includes a first high temperature performance metallic strip () formed of a thermally conductive alloy, including, Ni Cr, and Fe, spirally wound around a central axis (A) to present a first high temperature performance metallic winding () exposed to hot fluids. A first non-metallic filler strip () formed of a mica material is spirally wound outwardly of the first high temperature performance metallic winding () to form a first non-metallic filler winding (). A second high temperature performance metallic strip () formed of a stainless steel material is spirally wound outwardly of the first non-metallic filler winding (). A second non-metallic filler strip () formed of a graphite material is spirally wound outwardly of the second high temperature performance metallic winding ().

Bi-metal spiral wound gasket

A compression sensor gasket and method of construction thereof is provided. The gasket has a body with opposite sealing surfaces and a through passage configured to align with a chamber to be sealed. A through opening extends between the sealing surfaces to the through passage and has an annular chamfered surface. A pressure sensor assembly having a housing and a pressure sensor extending at least partially through the housing is disposed in the through opening. The pressure sensor has a pressure sensor tip configured to sense pressure within the chamber to be sealed. The housing has an outer annular tapered surface configured to register in radial alignment with the chamfered surface to facilitate forming a hermetic seal between the pressure sensor assembly and the gasket body.

Compression sensor gasket and method of construction

A compression sensor gasket assembly and method of construction thereof is provided. The compression sensor gasket assembly includes a gasket body having opposite sealing surfaces extending between an outer periphery and an inner periphery with the inner periphery bounding a through opening. The gasket body has a passage extending from the outer periphery through the inner periphery and a pressure sensor assembly releasably attached to the gasket body in the passage and being configured to sense pressure within the through opening. The pressure sensor assembly can be removed from the gasket body in service without having to disassemble clamped members from clamped abutment with the gasket assembly. Further, the pressure sensor assembly can be routed over a curved path extending between the outer and inner peripheries to navigate about features that may be present in the gasket body.
