  • Patent number: 5879146
    Abstract: The invention includes a wear indicator for a radially extensible vane compressor. The indicator is an elongate member having two longitudinal sections with a step inbetween. The step catches on a mating step formed in the compressor rotor when it is good and does not catch on the mating step when it is bad (i.e., worn). A repair person can test the wear of the indicator merely by attempting to withdraw the indicator. If it is removed it is worn, and if it is not removable, it is acceptable.
