縮機の異常検出機構。 A compressor housing having a cylinder chamber in which fluid is compressed, and for automatically opening and closing the cylinder chamber to suck fluid into the cylinder chamber or discharge fluid from the cylinder chamber according to a compression stroke. In a compressor having a valve mechanism, a voltage is applied to the valve mechanism, and the valve mechanism is insulated from the compressor casing in an open state and electrically connected to the compressor casing in a closed state. A contact switch is configured by a valve mechanism, and has a detection means for detecting conduction or non-conduction of the valve mechanism, and the detection means detects the compression operation of the compressor when the conduction or non-conduction continues for a predetermined period of time. An abnormality detection mechanism for a compressor, characterized in that the compressor is stopped.
