Abstract
A device intended to feed a gaseous high-pressure fluid to a platform supported on a frame on which is located a pressure source, said device comprising a rotating joint unit including two fluid conduct members mounted in relative rotational relationship to said platform along the geometrical axis around which said platform is rotating, one of said members being connected to fittings usable for feeding said fluid and located on said platform. The other member is intended to feed said pressure source, the fluid conduct member which is intended, in the joint unit, to be connected to said pressure source is connected to the latter by a releasable connecting member. The coupling of said member depends on the fluid feeding required by the user or by said fitting usable for the fluid feeding and mounted on said platform.
Claims8
A gaseous high-pressure fluid feeding device for feeding fluid to a rotating platform having a geometrical axis of rotation and including utilization fittings for using the fluid fed to said platform, said device comprising a high-pressure fluid source separate from the platform for feeding high-pressure fluid to the utilization fittings during a high-pressure fluid feeding operation;
- a rotating joint unit mounted on the platform and including fluid conduct means for fluidly interconnecting said utilization fittings and said high-pressure fluid source, a first portion of said fluid conduct means being connected to said utilization fittings and a second portion extending along said geometrical axis of rotation being connectable to said high-pressure fluid source;
- and connecting unit means between said second portion of said fluid conduct means and said high-pressure fluid source for establishing fluid communication therebetween, said connecting unit means having a portion thereof in communication with said fluid conduct means, another portion thereof in communication with said high-pressure fluid source, and components thereof movable from a spaced apart position to an engaged position for selectively establishing fluid communication between said high-pressure fluid source and said fluid conduct means so that fluid flows from said high pressure source to said utilization fittings, the establishment of fluid communication occurring during the high-pressure fluid feeding operation.
A high-pressure fluid feeding device for controlling the feeding of a fluid from a high-pressure source separate from a platform to means for utilizing fluid carried by the platform, the platform being rotatable about an axis of rotation, said device comprising:
- a rotating joint unit including fluid conduct means carried by the platform for establishing fluid communication between the high-pressure source and the means for utilizing fluid, said fluid conduct means rotating with the platform and having a duct receiving fluid from the high-pressure source;
- and
- connecting means for controlling fluid communication between said duct and the high-pressure source, said connecting means including a chamber in fluid communication with the high-pressure source and receiving an inlet end of said duct, said chamber being movable between a first closed position when fluid is fed from the high-pressure source through the chamber into said duct and a second position, the chamber being in the second position when fluid is not being fed from the high-pressure source into the duct, and said connecting means including biasing means for urging said chamber into the second position,
- said chamber being urged into the first closed position thereof by fluid being fed from the high-pressure source to the means for utilizing fluid.
