Title: Air compressor
Inventor: SETOYAMA MICHINOBU
IPC: F04B49/00
Filed: 1987-05-18
Abstract: PURPOSE:To prevent a suction valve from fluttering by opening an on-off valve in an unloader pipeline when tank internal pressure is more than the upper limit value, but when it is less than the lower limit value, opening this on-off valve after the elapse of the specified time, at the time of suspension of compressor operation. CONSTITUTION:An unloader pipeline 5 with a solenoid valve 4 is installed between an air tank 2 and a compressor body 3, and internal pressure in the tank is added to a piston 7 operating a suction valve 6. When the tank internal pressure is more than the upper limit value at the time of suspension of compressor operation, the solenoid valve 4 is opened at once, and air pressure acts on the piston 7, thus the suction valve 6 is opened. And, when the tank internal pressure is less than the lower limit value, the suction valve 6 is opened after the elapse of the specified time. Accordingly, any fluttering of the suction valve is thus preventable.
