Title:
PRESSURE BOOSTER
Document Type and Number:
WIPO Patent Application WO/2018/096738
Kind Code:
A1
Abstract:
A first position detection sensor (70a) and a second position detection sensor (70b) of a pressure booster (10) detect the position of a first piston (44) or a second piston (46). A fluid supply mechanism (48) supplies a fluid to a first pressure-boosting chamber (34a) and/or a second pressure-boosting chamber (36a). On the basis of the detection results of the first position detection sensor (70a) and the second position detection sensor (70b), the fluid supply mechanism (48) switches between performing an operation for supplying fluid to a first drive chamber (34b) and discharging fluid from a second drive chamber (36b), and performing an operation for discharging fluid from the first drive chamber (34b) and supplying fluid to the second drive chamber (36b).
