Liquid discharge module, liquid discharge head, and liquid discharge apparatus

A liquid discharge module comprising:

• a nozzle plate including:
• a first face;
• a second face opposite to the first face;
• and
• a nozzle hole through which a liquid is discharged from the second face, the nozzle hole including at least two different inner diameters between the first face and the second face;
• a housing including a liquid chamber:
• facing the first face of the nozzle plate;
• and
• communicating with the nozzle hole,
• the housing supporting the nozzle plate;
• a valve in the liquid chamber, the valve to contact the first face of the nozzle plate to form a sealed portion between the valve and the nozzle plate to close the nozzle hole, wherein the valve includes:
• an elastic seal to elastically contact the first face of the nozzle plate to form the sealed portion, and
• a needle supporting the elastic seal at a leading end of the needle adjacent to the nozzle hole;
• and
• a mover to move the valve in a contact-separation direction between:
• a contact position at which the valve contacts the nozzle plate;
• and
• a separation position at which the valve is separated from the nozzle plate,
• wherein the elastic seal includes a recess facing the nozzle plate,
• the liquid discharge module further comprising:
• a restrictor attached to the housing,
• wherein the mover is fixed by the restrictor on an end side opposite to the valve.
