  • Patent number: 8985638
    Abstract: Slip joint having a stacked washer seal, a male part and a female part. The female part has a small and a large inner diameter. The male part has substantially constant inner and outer diameters and a ring on the outer diameter. A gap is located between the male and female part. At least two washers and a flat shim are located in the gap. Each washer and flat shim has a first side, a second side, a first end and a second end. The first side of a first washer abuts an end of the male part. A second side of the washer contacts a first side of a flat shim. The second side of the shim contacts the first side of a second washer. The second side of the second washer contacts a first side of a second flat shim or an end of the female part.

  • Patent number: 8128098
    Abstract: A gasket is described having a middle layer, two metal layers and an uppermost and a lowermost layer. The middle layer may have an upper surface and a lower surface defining a first planar portion, a wave portion and a second planar portion. The metal layers sandwich the middle layer and are substantially planar. An uppermost active layer is located above the first intermediate layer. The uppermost active layer comprises a first planar portion, a first bead portion, and a second planar portion. The lowermost active layer is located below the second intermediate layer. The lowermost active layer also comprises a first planar portion, a first bead portion, and a second planar portion.

  • Patent number: 6453892
    Abstract: A damped steel baffle for an engine cam cover aids in separation of oil mist entrained in a flow of crankcase air vented through the cam cover, and directs the air to a PCV valve atop the cover. The baffle forms a channel for the air, and effectively absorbs noise generated within the cover. Oil droplets condense on channel and baffle surfaces, and drain to an engine oil sump. The interface between baffle and cam cover is sealed with a foam gasket layer or RTV sealant. The baffle is constructed of two metal layers joined together by a thin layer of viscoelastic adhesive that converts vibrational energy into heat to dampen resonant vibrations. Amplitudes of vibration are significantly lower than for plain steel baffles, hence lower sound radiation is achieved. The individual steel layers are 0.2 to 0.6 mm thick; the viscoelastic layer has a thickness up to 0.15 mm.
