Abstract
A telescoping fluid coupling (10,110) is provided for use with a fluid flow device (12) and includes a coupling body (14,114) having a fluid port (16,116) extending along a longitudinal axis (18,118). A retainer (20,120) is fixed to the body (14,114) and includes a retaining shoulder (26,126). A flange (22,122) is mounted to the fluid port (16,116) and includes a radially inwardly facing guide surface (36,136) that surrounds a mount surface (24,124) and extends longitudinally along the axis (18,118) to provide guided, sliding translation of the guide surface (36,136) relative to the mount surface (24,124) along the axis (18,118). The flange (22,122) further includes a stop shoulder (38,138) to engage the retaining shoulder (26,126) to limit the translation of the flange (22,122) along the axis (18,128).
Claims14
A telescoping fluid coupling for use with a fluid flow device, the coupling comprising:
- a coupling body having a fluid port extending along a longitudinal axis;
- a retainer fixed to the body, the retainer including a retaining shoulder;
- a radially outwardly facing mount surface surrounding the fluid port;
- and
- a flange mounted to the fluid port for translation along the axis relative to the fluid port and configured to be fixed via a plurality of releasable fasteners to a mating flange to form a sealed connection therewith, the flange including:
- a face surface configured for sealed engagement with a mating face surface on the mating flange;
- a radially inwardly facing guide surface that surrounds the mount surface and extends longitudinally along the axis, the guide surface having a sliding fit with the mount surface to provide guided, sliding translation of the guide surface relative to the mount surface along the axis;
- and
- a stop shoulder located inboard of the retainer shoulder, the stop shoulder engaging the retaining shoulder to limit the translation of the flange along the axis relative to the fluid port;
- and
- at least one gasket located between the guide surface and the mount surface to create a seal between the guide surface and the mount surface;
- wherein:
- the flange includes an end surface facing opposite of the face surface;
- the fluid port includes a spacer surface spaced inboard of the end surface;
- and
- the telescoping coupling further comprises a spacer that is movable between a first position wherein the spacer is sandwiched between the end surface and the spacer surface to limit translation of the flange along the longitudinal axis, and a second position wherein the spacer is not located between the end surface and the spacer surface.
