Abstract

PURPOSE:To improve reliability and simplify and lower the cost of a device in the belt breakage detecting device of a V-belt driving device by providing wiring for a compressor controlling circuit on the outer peripheral portion of a V-belt. CONSTITUTION:A V-pulley 1 receives the transmission of power from an M- sheave 2 via a V-belt 3. On the outer peripheral portion of the V-belt 3, wiring which is provided at a right angle to the V-belt is divided into a wiring (1) 4 and a wiring (2) 5 by means of a connector 6. The V-belt which was broken during operation is brought into contact with the wiring 4 or wiring 5 dividing a lead wire from the connector portion. As a result, the coil of the connector 6 is demagnetized without electrifying a second circuit, to stop a compressor. At the same time, an unloader for the compressor is totally closed preventing the jetting out of oil. Thereby, reliability can be improved while simplifying and lowering the cost of a device.

If the V-belt breaks during operation, the V-belt will jump up and come into contact with this conductor wire, causing part of the connector to break. comes off. At this moment, the control circuit is disconnected.

(2) Pulley 1 receives power from M sheave 2 via V-belt 8. The outer periphery of the V-belt 8 is perpendicular to the V-belt, and a portion A-B of the control circuit shown in FIG.
It is divided into two wiring lines (2). The V-belt that breaks during operation comes into contact with wiring (1) or wiring (2) and causes the conductor to split from a part of the connector. As a result, the control circuit shown in FIG. 2 is not energized, the coil of the contactor 52 is demagnetized, and the compressor is stopped. At the same time, the solenoid valve 20P is demagnetized, the compressor unloader is fully closed, and oil spout can be prevented.
