Abstract
A cooling device for a superconductor, in particular a high-temperature superconductor of a synchronous machine includes a cooling circuit for a coolant, wherein the coolant liquefied in a cold head having a condenser is conveyed to the superconductor to be cooled, and is returned to the condenser in a gaseous state. In order to convey the coolant to the superconductor to be cooled, pressure is applied to the coolant.

1-9. (canceled)
A cooling device for a superconductor of a synchronous machine, comprising:
- a cold head having a condenser for liquefying a coolant;
- a cooling circuit for conveying the liquefied coolant to the superconductor to be cooled and returning the coolant to the condenser in a gaseous state;
- and
- a pressure-application device configured to subject the coolant in the cooling circuit to a pressure as the coolant is conveyed to the superconductor, said pressure-application device having a storage container, a plunger received in the storage container, and a spring acting on the plunger to place the coolant under pressure in the storage container.
