Abstract:
     The present invention provides the principle and structure of a variable film capacitor with deformable rotor. The rotor and stator are close to the medium film without air gap. The capacitance is changed by means of lifting or pressing the rotor. One rator may constitute a multigang variable capacitor together with several stators. Or else, several rotors driven with an insulating carrier and several stators may constitute a multigang variable capacitor. Six practical examples are provided. The variable capacitor has high precision, low noise and large rotation range of rotor, and its rotor may be led out without sliding contact.
