Title:
PRESSURE GENERATOR DEVICE
Document Type and Number:
Japanese Patent JP3814211
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a miniaturized pressure generator device for generating negative or positive pressure air in pulses.
SOLUTION: A driving side piston 17 fixed to a driving side piston rod 15 and a driven side piston 13 fixed to a driven side piston rod 14 are stored inside a driving side cylinder 16 and a driven side cylinder 10 respectively in such a way that they can reciprocate in the axial direction. The piston rods 15 and 14 project outward through rod covers 42 and 12 respectively, and both are connected by a connection plate 43. The driving side piston 17 is driven as compressed air is fed to pressure chambers 44 and 15, and the driven side piston 13 is operated synchronously. Expansion/contraction chambers 21 and 22 are expanded/contracted according to the reciprocation of the driven side piston 13, and the pressure in negative pressure feeding pathways 23 and 24 becomes negative by negative pressure check valves 31, 32 and exhaust check valves 33 and 34.
