Title:
PRESSURIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/243286
Kind Code:
A1
Abstract:
A piston axial force information detection unit (53) detects piston axial force information pertaining to an axial force applied to a piston body (21). A friction information storage unit (62) stores friction information pertaining to a frictional force between a piston seal (23) and a pressure vessel (10) when the piston body (21) moves relative to the pressure vessel (10). A drive control unit (65) controls a drive device (40) on the basis of the piston axial force information and the friction information. In a holding stroke for controlling the pressure inside the pressure vessel (10) so as to be constantly held, the drive control unit (65) controls the drive device (40) so that the piston body (21) reciprocates with respect to the pressure vessel (10).
