<p>PURPOSE:To detect rotational frequency and inclination by providing a detector adapted to transmit a detection signal every time a detected body mounted on an oscillating plate passes between the center position of an oscillating motion locus line of the detected body at the time of the minimum oscillating inclination and the limit point thereof on piston side. CONSTITUTION:A pin 45 is fixed to an oscillating plate 41, and a signal pulse is generated by an electromagnetic induction type detector 48 every time the pin 45 passes a detecting portion 48a to be supplied to an air control unit 19. The electromagnetic induction type detector 48 is disposed in such a manner that in the passing position of the pin 45, the detecting portion 48a exists at the center position of an oscillating motion locus line of the pin 45 when the oscillating plate 41 is inclined at its minimum angle. Accordingly, the rotational frequency of a compressor and the inclination of the oscillating plate can be detected at the same time.</p> |
