12 results about "Rotary union" patented technology

A rotary union is a union that allows for rotation of the united parts. It is thus a device that provides a seal between a stationary supply passage (such as pipe or tubing) and a rotating part (such as a drum, cylinder, or spindle) to permit the flow of a fluid into and/or out of the rotating part. Fluids typically used with rotary joints and rotating unions include various heat transfer media and fluid power media such as steam, water, thermal oil, hydraulic fluid, and coolants. A rotary union is sometimes referred to as a rotating union, rotary valve, swivel union, rotorseal,rotary couplings, rotary joint, rotating joints, hydraulic coupling, pneumatic rotary union, through bore rotary union, air rotary union, electrical rotary union, or vacuum rotary union...

Cooling system for superconducting wind power generator

Techniques are described for a wind power generator in which a refrigerant such as liquid helium and / or helium gas is applied to superconducting magnets via thermally conductive flexible structures. These structures thermally couple the refrigerant channels to the magnets, and / or to a thermally conductive structure (e.g., metal plate) to which the magnets are thermally coupled. The thermally conductive flexible structures may be arranged so that motion of the magnets relative to the cryogenic channels that cool the structures during heating and / or cooling of the magnets does not result in damage to the thermal connection between the channels and the magnets. The stationary stage of the generator may house a cooling station, and transfer the refrigerant to the rotary stage via a suitable rotary union.
