摘要： A pressure regulating unit capable of suitably regulating pressure to be applied to liquid, a liquid supplying apparatus, and a liquid ejecting apparatus are provided. 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 part of the pressure chamber is formed of a flexible film. A valve including a valve body and a valve seat adjusts an opening degree of the ink communication path. An urging member applies, to the valve, a first urging force acting in a direction in which the ink communication path is closed. An urging member applies, to the film, a second urging force that is greater than the first urging force and acts in a displacement direction in which the volume of the pressure chamber is reduced.

摘要： In a liquid ejection head in which ejection modules are arrayed on a flow path forming member, each ejection module includes a recording element substrate provided on a support member. The recording element substrate includes a liquid supply channel, a liquid collection channel, and ejection ports. The support member includes supply-side liquid communication ports communicating with the liquid supply channel and collection-side liquid communication ports communicating with the liquid collection channel. The supply-side liquid communication ports and the collection-side liquid communication ports are alternately provided along the direction in which the ejection modules are arrayed. The closest pair of liquid communication ports in the adjacent ends of two adjacent ejection modules are both supply-side or collection-side liquid communication ports.
