  • Method of releasing a stuck air value and sticking release apparatus
    Patent number: 5771000
    Abstract: The present invention provides a method of releasing a stuck air valve and also a sticking release apparatus that detects sticking of the air valve from a discrepancy in the waveform of an excitation current of a DC solenoid, then uses that current to release the sticking of the air valve.
