Liquid supply device and inkjet recording device

A liquid supply device comprising:

• a flow path along which a liquid is distributed;
• and
• a pump that is connected to the flow path to move the liquid in the flow path,
• wherein the flow path includes:
• a plurality of division flow paths that are arranged in parallel such that the flow path branches into the division flow paths at a branch portion and the division flow paths merge into one path at a merging portion;
• and
• ejection portions which are respectively arranged in the division flow paths, and each of which ejects the liquid in the corresponding division flow path to an outside, and
• the ejection portion includes:
• a nozzle that ejects the liquid to the outside;
• a check valve that
• is arranged on an upstream side of the nozzle in a direction of ejection of the liquid,
• prevents the liquid from being distributed in a direction opposite to the direction of ejection of the liquid and
• distributes the liquid in the direction of ejection of the liquid toward the nozzle when a pressure of the liquid in the division flow path is equal to or greater than a first pressure;
• and
• a flow path resistant member that
• is arranged between the check valve and the nozzle in the direction of ejection of the liquid,
• generates resistance to the distribution of the liquid and
• distributes the liquid in the direction of ejection of the liquid toward the nozzle when a pressure of the liquid that has passed through the check valve is equal to or greater than a second pressure greater than the first pressure.
