Abstract:
Ink is supplied to a print head through a pressure compensation mechanism and a common collection flow path in a case where a predetermined differential pressure or higher between a pressure in a common supply flow path of the print head and a pressure in a common collection flow path of the print head is generated. As a result, liquid refillability for the liquid ejection head is improved while retaining a liquid circulating function in the liquid ejection head so as to stabilize a liquid ejecting state in the liquid ejection head.

Claim (Index 16):
A liquid ejection head comprising:\n a pressure chamber including an energy generating element for ejecting liquid provided therein; a supply flow path for liquid which communicates with the pressure chamber; a collection flow path for liquid which communicates with the pressure chamber; a pressure control unit configured to generate a pressure difference between the supply flow path and the collection flow path so as to supply liquid from the supply flow path to the pressure chamber and to collect liquid from the pressure chamber to the collection flow path; and a pressure compensation unit configured to supply liquid to the collection flow path in a case where pressure in the collection flow path is a predetermined pressure or lower.
