  • Publication number: 20080179835
    Abstract: A shaft seal includes an elastomeric annular body having a radially inwardly protruding annular lip. An annular outer case receives the elastomeric annular body. An annular inner case is embedded into the elastomeric annular body. An annular insert is positioned adjacent the inner case. A backup/support insert is received in a recessed pocket in the elastomeric body and outboard of an axially extending annular bead protruding from the body and compressed sealingly against the radially inward extending leg of the seals annular outer case. The backup/support insert and axially extending annular bead act to prevent sealed fluid pressure from acting against a rind portion of the elastomeric body thus leaving outwardly extending beads of the rind portion free to compress or decompress to accommodate eccentric deflection of the shaft. The outer case, the insert, the backup insert and the inner case support the lip and compensate for shaft offset.

  • Publication number: 20080157482
    Abstract: A gasket for a valve in an internal combustion engine is provided with a first elastically deformable portion adapted to cooperate with a rod of the valve. A second elastically deformable portion is adapted to cooperate with an outer surface of a guide element of the valve, and a third elastically deformable portion is interposed between the first and the second elastically deformable portions and bearing a cantilevered gas tight seal lip is adapted to cooperate with the rod of the valve. The lip displays a frustoconical configuration with a section decreasing in opposite direction to the pressure forces directed towards the first elastically deformable portion and is connected to the third elastically deformable portion at its greater section part. The lip is further connected on the side exposed to the pressure forces, to the third elastically deformable portion by a surface bearing one or more waves.

  • Publication number: 20080157439
    Abstract: Methods for preparing a shaped rubber article, comprising admixing at least one thermoplastic material and at least one elastomer material to provide a processable and dimensionally stable rubber composition, shaping the composition, and irradiating the composition to form the shaped rubber article. The dimensional stability of the uncured composition may be provided by partial dynamic vulcanization, high performance reinforcing fillers, fractional curing, or combinations thereof. The elastomer material is present in an amount greater than about 65% by weight based on the total weight of the thermoplastic and elastomer materials present in the admixture.

  • Publication number: 20080157481
    Abstract: A dynamic shaft seal assembly is provided including a dynamic seal for engaging a rotary shaft. The dynamic seal includes a base portion that is mounted within a casing and has an axially extending barrel portion extending from a radially inner end of the base portion. The axially extending barrel portion terminates in a radially extending leg portion which extends inwardly from an end of the axially extending portion. A generally conically shaped seal portion extends from an end of the radially extending portion and the seal portion includes a radially inner face engaging the shaft and a radially outer face having a stiffening bead integrally formed thereon. The stiffening bead reduces the seal's propensity for “bell mouthing” while the axially extending barrel portion provides improved shaft followability for the dynamic seal.

  • Publication number: 20080157480
    Abstract: A gasket for a valve in an internal combustion engine is provided with a support element having a tubular configuration according to an axis and coaxially mounted on the valve. An elastically deformable element is interposed between the support element and the valve. The support element includes a first portion elongated according to the above mentioned axis, and a second portion extending from the first portion in a direction transversal to the axis, at least partially housed in an annular seat of the elastically deformable element and having its radially outermost end connected to the first portion itself. The support element comprises a third portion extending from the radially innermost end of the second portion and folded on the second portion itself so as to generate, in the folding area, a rounded edge cooperating with the annular seat of the elastically deformable element.

  • Publication number: 20080149868
    Abstract: A valve includes a housing having an inlet (3), an outlet (1) and a movable sealing member (2) which allows the inlet (3) and the outlet (1) to be connected in fluid communication with each other, the sealing member (2) having associated therewith effective areas (4b) to which pressure can be applied, and sealing areas (4), and the sealing member (2) further having associated therewith a sealing seat (4a) for sealing the inlet (3) from the outlet (1). In order to provide a valve by which pressure can be relieved in a very short time, the sealing member (2) has associated therewith a conduit (2a) by which the inlet (3) and the outlet (1) can be connected in fluid communication with each other when the sealing member (2) rests on the sealing seat (4a).

  • Publication number: 20080149881
    Abstract: Polymeric binder blended from thermoplastic and uncured elastomer binds magnetizable particulate in segmentally magnetizable materials used for encoder targets used in encoders and assemblies where encoders determine rate of motion. The polymeric binder has a dynamic mechanical thermal analyzer tangent delta value (ASTM E 1640-94) not greater than 0.1 at a temperature not less than the liquefaction supra point temperature of the thermoplastic when cured with radiation (preferably electron beam radiation) prior to being blended with either the magnetizable particulate or with other filler materials. The binder effects encoder targets evidencing robustness to thermal or chemical agent stress. Pre-cured blends of magnetizable particulate in the binder evidence good extrusion (pultrusion) performance.
