<P>PROBLEM TO BE SOLVED: To provide a booster that can be miniaturized while aiming at higher efficiency. <P>SOLUTION: The booster includes: a flow piston 41 to which driving force is applied to operate; a primary-side oil chamber 121 in which oil therein is pressurized by the flow piston 41; a secondary-side oil chamber 122 to which oil from the primary-side oil chamber 121 is supplied via a communication path 141; a switching mechanism 221 which closes the communication path 141 associated with supply of oil from the primary-side oil chamber 121 to the secondary-side oil chamber 122; an increase-pressure piston 101 which receives hydraulic pressure in the primary-side oil chamber 121 to retreat, and pressurizes oil in the secondary-side oil chamber 122; and an output port 201 for output of oil in the secondary-side oil chamber 122. <P>COPYRIGHT: (C)2013,JPO&INPIT |
