する流体供給装置。 A high-pressure pump 1 has pressure increase cylinder devices 2 and 3 and a drive cylinder device 4, and includes pressure increase cylinder devices 2, 3, and a drive cylinder device 4.
3 is a pressure increase cylinder part 5 in which fluid chambers 7, 8, and 9 are formed, and a pressure increase cylinder part 5 that is slidably provided in the axial direction and is slid by a drive cylinder device 4. A plunger section that has a plunger 6 and sucks fluid into the fluid chambers 7, 8, 9 by sliding in the axial direction of the pressure increase plunger 6, and discharges the sucked fluid to supply it to the fluid device 27. 17, 18, and 19 are formed, and the pressure receiving area of the fluid pressure acting in the axial direction on the drive piston 22 of the drive cylinder device 4 at the time of fluid discharge from the pressure increase cylinder devices 2 and 3 is the pressure increase plunger 6.
In the pressure increasing cylinder section 5, a plurality of fluid chambers 7, 8, and 9 are arranged independently in the axial direction, and the pressure increasing area is larger than the pressure receiving area of the fluid pressure acting in the axial direction. Each fluid chamber 7, 8, 9 is attached to the plunger 6.
A plurality of plunger portions 17, 18, 19 are arranged in the axial direction, and each fluid chamber 7, 8, 9 and a single fluid device 27 are connected to a fluid supply path 29, 31, 3.
3, 36, 38, 41, and each supply path 29, 31, 33, 36, 38, 41 is provided with a non-return check that allows fluid to flow only from each fluid chamber 7, 8, 9 to the fluid device 27. Valve 30, 32, 34, 35, 3
7, 39, 40, 42, 53, 54 are provided,
A fluid supply device characterized in that drain passages 46, 47, and 48, which can be opened and closed, are connected to each of the fluid chambers 7, 8, and 9, respectively.
