Title: Pneumatic compressor
Inventor: ODAGIRI MEIJI
IPC: F04B49/06
Filed: 1990-03-20
Abstract: PURPOSE:To prevent useless power consumption by interrupting provision of three-phase driving pulses to a driving means during an interval of reciprocal motion of piston in which the piston is subjected to inertia. CONSTITUTION:When a piston reaches a top dead center (crank angle pi), a top dead center sensor 4 outputs a detection signal which is fed to a CPU 14. The CPU 14 commands an inverter module (INV) 17 to interrupt provision of three-phase driving pulse. Consequently, the piston is subjected to inertia of itself or due to the motion of a pulley and moves from the top dead center toward a bottom dead center (crank angle 2pi). When the piston reaches the bottom dead center, the CPU 14 commands the INV 17 to start provision of the three-phase driving pulse. When the INV 17 resumes provision of the three- phase driving pulse, the piston moves from the bottom dead center toward the top dead center (crank angle 4pi) thus pressure feed the air.
