Abstract:
An inkjet recording apparatus includes a recording head, an ink tank, a supply flow path, a supply pump located in the supply flow path, a collection flow path, a relief flow path connecting a first position in the supply flow path to a second position in the supply flow path, wherein the first position is located at a downstream side of the supply pump in the supply flow path and the second position located at an upstream side of the supply pump in the supply flow path, and a differential pressure regulating valve located in the relief flow path and configured to, in a case where the pressure of the pumped ink in the supply flow path is larger than a predetermined value, open the relief flow path so as to allow ink in the supply flow path to flow from the first position to the second position.

Claim (Index 7):
The inkjet recording apparatus according to  claim 6 , wherein the recording head further includes a common supply flow path connected to the supply flow path and configured to supply ink to the pressure chamber, a common collection flow path connected to the supply flow path and the collection flow path and configured to collect ink from the pressure chamber, a first pressure control unit located between the supply flow path and the common supply flow path and configured to control a pressure, and a second pressure control unit located between the supply flow path and the common collection flow path and configured to control a pressure, and the second pressure control unit generates a stronger negative pressure than the first pressure control unit.
