摘要： A high pressure fluid delivery conduit for use at pressures of 30,000 psi or more permitting relative movement of one end relative to the other only when fluid pressure is not applied thereto. The conduit is formed by a plurality of rigid tube-like sections arranged end-to-end and a plurality of movable joints connecting the sections. Each joint has an outer member in which an inner member is rotatably received. Outer and inner passageways defined by the outer and inner members at an interface location, respectively, communicate with each other regardless of the positions of the members. A pair of ring-shaped seals are disposed between the outer and inner members, for radial expansion upon the application of fluid pressure thereto to prevent the escape of the fluid. The seals are arranged on opposite sides of the interface location.

摘要： In an apparatus for forming leak-proof joints between tubes and a tube sheet by the internal application of hydraulic swaging pressure, the flow of pressurized fluid from an adjustable pressure reduction valve is permitted or interrupted by a control valve. An actuator moves the control valve between its flow permitting and interrupting positions in response to a control signal. In the sensor, which is connected to the input and output sides of the control valve, a piston is movable in response to the difference in the input and output pressures to produce the control signal when a predetermined comparative pressure relationship exists.

摘要： In a device for confining a pressurized working fluid within a tube to be expanded radially, a support to be positioned axially within the tube and at least one sealing member encircling the support. The sealing member is deformable so that it expands radially against the inside of the tube upon axial compression by the force of a pressurized working fluid introduced into the tube. A centering means is provided that prevents angular movement of the sealing member relative to the longitudinal axis of the tube, thereby forcing the sealing member to assume a radially centered position within the tube as it expands.
