PURPOSE:To increase the discharging capability by compressing air with a piston reciprocated by the rotation of a cam to feed it to a combustion chamber, injecting fuel into the combustion chamber to ignite and explode it, and utilizing the explosion energy to discharge slurry. CONSTITUTION:When a shaft 4 is rotated by a hydraulic motor 1, a cam 3 is eccentrically rotated accordingly, and radially arranged multiple pistons 7 are vertically moved in cylinders 6 via rollers 8 in slide contact with a recessed groove 5 around the cam. The outside air sucked through an inlet valve 13 is compressed into the high-temperature compressed air, which is discharged at once into a combustion chamber 14 via an outlet valve 15. When the outlet valve 15 is closed and an exhaust port 21 is sealed by a check valve 20, a fixed quantity of fuel is injected into the combustion chamber 14 through a fuel injection nozzle 18, it is exploded and burnt by an ignition plug 19, the check valve 20 is simultaneously opened, and the high-pressure combustion air is sprayed through the exhaust port 21. This spray energy is utilized to discharge slurry. |
