Intensifier and atomizer using intensifier

An intensifier configured to pressurize raw material using medium supplied from a driving pump, the intensifier comprising:

• a low-pressure cylinder to which the medium is supplied;
• a high-pressure cylinder fixed to the low-pressure cylinder;
• a piston configured to slide inside the low-pressure cylinder and the high-pressure cylinder by the medium supplied to the low-pressure cylinder;
• a bottom adapter configured to support the piston for sliding motion, the bottom adapter including a cleaning liquid supply port to which cleaning liquid is supplied and a cleaning liquid discharge port through which the cleaning liquid supplied into the bottom adapter is discharged;
• a fixing portion disposed radially outside of and overlying the bottom adapter and configured to fix the bottom adapter inside the high-pressure cylinder;
• and
• an axially extending resin portion disposed along an inner periphery of the bottom adapter in position to support sliding movement of the piston,
• wherein a cleaning flow path through which the cleaning liquid is discharged from the cleaning liquid discharge port extends axially along an outer periphery of the bottom adapter and an inner periphery of the fixing portion in a gap therebetween.
