Title:
A manufacturing method of drop fuel injection equipment and drop fuel injection equipment
Document Type and Number:
Japanese Patent JP6201584
Kind Code:
B2
Abstract:
A liquid droplet jetting apparatus includes: a nozzle plate (11) formed with a nozzle (30); a first flow passage formation body (12) stacked on the nozzle plate and formed with a liquid flow passage including a pressure chamber (31) in communication with the nozzle; a piezoelectric element (19) arranged on a surface of the first flow passage formation body on the side opposite to the nozzle plate and configured to apply a pressure to a liquid in the pressure chamber; and a second flow passage (14+15) formation body arranged on the side opposite to the nozzle plate with respect to the first flow passage formation body so as not to hinder driving of the piezoelectric element. The second flow passage formation body is formed with a liquid storing chamber (37) and a throttle flow passage (33) configured to restrict an amount of the liquid flowing from the liquid storing chamber into the pressure chamber.
