Document Type and Number:
Japanese Patent JP4272837
Kind Code:
B2
Abstract:
The present invention discloses an elastic transformable body (10) for adjusting vapor pressure, a vapor pressure adjustment chamber (8) using the same, an ink-jet recording head having a vapor pressure adjustment device and an ink-jet recording device having the recording head, and more particularly to a vapor pressure adjustment device for adjusting negative pressure generated in a liquid chamber in an ink-jet recording head when discharging ink. The pressure adjustment chamber has at least one elastic transformation body having a changeable volume according to vapor pressure to adjust the vapor pressure in a container communicated thereto and a support for supporting the elastic transformation body to the container. In the pressure adjustment chamber, the elastic transformation body includes an approximately circular opening and two surfaces (10a) approximately flat before transformation at an outer circumference, in which the two surfaces have a shape extended through a curved portion (10b) at a front end opposite to the opening.
