Abstract

A vibration isolating clamp apparatus for maintaining an end of a tube in sealing abutment with a surface, in substantial alignment with an aperture disposed in the surface, suitable for use in extreme temperature environments, wherein the tube has an outwardly-projecting, annular bead arranged substantially adjacent the portion of the tube adjacent the aperture in the surface. A retainer member is provided with a clamp attachment region and a tube retaining region. Means for enabling affixation of the clamp apparatus to the surface are disposed in the clamp attachment region. In the tube retaining region, means are provided for insertably receiving the extreme end of the tube. Bead sealing means entrap the bead between the tube retaining region and the surface. In the tube retaining region, tube isolation means limit the magnitude of transverse vibrations of the end of the tube, proximate to and beyond the bead, and away from the extreme end of the tube.

Dependent claims

A vibration isolating clamp apparatus for maintaining an end of a fluid bearing tube having a longitudinal axis, in substantially sealing abutment with a surface and in substantial alignment with an aperture disposed in said surface, suitable for use in extreme temperature environments, in which said tube includes a substantially outwardly projecting annular bead positioned substantially at the portion of said tube adjacent said aperture in said surface, said vibration isolating clamp apparatus comprising:

a retainer member having a clamp attachment region, a tube retaining region, and a first, bottom clamp surface and a second, top clamp surface substantially opposite said first, bottom clamp surface;
said clamp attachment region having, operably disposed therein, means for enabling affixation of the clamp apparatus to said surface;
tube aperture means operably arranged to extend through the tube retaining region from said first, bottom clamp surface to said second, top clamp surface,
said tube aperture means having a first interior diameter at a position immediately adjacent said projecting annular bead;
bead sealing means operably arranged about the tube aperture means substantially adjacent to the first, bottom clamp surface for receiving and rigidly restraining the bead, so as to entrap the bead between at least a portion of said tube retaining region and said surface;
and
tube isolation means, longitudinally disposed from said bead sealing means, for isolating and limiting the magnitude of transverse vibrations of said end of said tube, proximate to said bead,
said tube isolation means being formed as a radially, inwardly projecting, annular metallic ridge, having a second interior diameter less than said first interior diameter of said tube aperture means,
said annular ridge being arranged within the tube aperture means in a position substantially adjacent said second, top clamp surface of said retainer member, so as to impose substantially rigid limits on the magnitude of said transverse vibrations.

A vibration isolating clamp apparatus for maintaining an end of a tube in substantially sealing abutment with a surface and in substantial alignment with an aperture disposed in said surface, suitable for use in extreme temperature environments, in which said tube includes a substantially outwardly projecting annular bead positioned substantially at the portion of said tube adjacent said aperture in said surface, said vibration isolating clamp apparatus comprising:

a retainer member having a clamp attachment region, a tube retaining region, and a first, bottom clamp surface and a second, top clamp surface substantially opposite said first, bottom clamp surface;
said clamp attachment region having, operably disposed therein, means for enabling affixation of the clamp apparatus to said surface;
tube aperture means operably arranged to extend through the tube retaining region from the first, bottom clamp surface to the second, top clamp surface,
bead sealing means operably arranged around the tube aperture means adjacent to the first, bottom clamp surface for receiving and restrainably accommodating the bead, so as to entrap the bead between at least a portion of said tube retaining region and said surface,
said bead sealing means being configured in the form of a chamfer, operably disposed immediately adjacent to and radially outwardly flared from the tube aperture means, and receding radially inwardly, from the first, bottom clamp surface;
and
tube isolation means, independent of said bead sealing means, for isolating and limiting the magnitude of transverse vibrations of said end of said tube, proximate to said bead,
said tube isolation means being formed as a radially, inwardly projecting annular ridge, arranged within the tube aperture means, substantially adjacent the second, top clamp surface of said retainer member,
said annular ridge being formed as a radially, inwardly projecting edge, conically and operably disposed at the second, top clamp surface in the tube retaining region, such that the tube aperture means has a substantially continuously increasing diameter, from the second, top clamp surface to the chamfer.
