Abstract
The present invention provides a pressure regulating unit capable of applying a stable pressure so as to supply liquid, a liquid supplying apparatus, and a liquid ejecting apparatus. An ink communication path allows an ink introducing chamber communicating with an ink inlet and a pressure chamber communicating with an ink outlet to communicate with each other. A valve including a valve body and a valve seat adjusts the opening degree of the ink communication path. An urging member applies, to the valve, an urging force that acts in a direction in which the ink communication path is closed and increases according to an decrease in pressure in the ink introducing chamber.
