Document Type and Number:
Japanese Patent JPH09501218
Kind Code:
A
Abstract:
The gas driven oscillator 10 employs as its main part an engine 11 having a casing 12 and a pair of expansion chambers 13 and 14 on either side of a floating piston 15 adapted to reciprocate within the cylinder 12. The piston is mounted on a piston rod 16 extending through the cylinder 12 and into a compressor 17, the compressor 17 having a cylinder 18 and a piston 19 mounted on the piston rod 16 to move in concert with the piston 15. An air storage tank 20 holds compressed air typically at a pressure between 100psi to 300psi. The compressed air in tank 20 can be generated using a compressor located upstream. The upstream compressor can be driven by any suitable means including electric motor, internal combustion engine, windmill or the like. A valve 21 downstream of the tank 20 controls delivery of the compressed air from the tank 20 to the engine 11 via a pair of valves 22 and 23 with the valves 22 and 23 being mounted on an adjustment screw and slidably disposed on the piston rod 16. The spacing between the valves 22 and 23 can be adjusted in order to vary the amplitude of the piston 15 within the cylinder 12. The valves can be moved in opposite directions and an equal amount. The piston rod 16 includes spaced slots 24 and 25 which alternately align with passages inside the respective valves 22 and 23 to deliver a pulse of compressed air from the tank 20 to the respective chambers of the cylinder 12 at each movement of alignment. The piston 15 oscillates according to an amplitude set by the spacing between the valves 22 and 23. The valves 22 and 23 are mounted on the adjuster screw 26 so they can be moved together or apart as desired.
