Conduit system for a lithographic apparatus, lithographic apparatus, pump, and method for substantially reducing vibrations in a conduit system

摘要

A conduit system for a lithographic apparatus is disclosed, the conduit system including a conduit configured to guide a liquid or liquid-gas mixture, and a gas injection nozzle configured to introduce a gas in the liquid or liquid-gas mixture to at least partially absorb pressure peaks or waves in the liquid or liquid-gas mixture. In an embodiment, the gas injection nozzle may be arranged in a pump of the conduit system. The pump further includes a pump inlet, a pump outlet and a pump chamber between the pump inlet and the pump outlet arranged for compression of the liquid or liquid-gas mixture.
