A new type torque limiter for the continuous variable displacement compressor has been developed. The limiter should meet conflicting requirements of strength under normal operating conditions on the one hand, and limiter characteristics on the other. This technology was achieved by special metal and special limiter shape. As a result, it has achieved various superior characteristics, such as accurate limiter torque and light weight. One of the reasons is that limiter torque hardly vary with temperature and deformation velocity.
