ABSTRACT:
The eccentric wheel, which is driven to rotate in the housing of a compressor, having two eccentric axles longitudinally aligned at two opposite ends for mounting a pair of links to hold a blocking plate. The blocking plate is carried by the links to displace when it is constantly disposed in contact with the eccentric wheel, and therefore, friction between the blocking plate and the eccentric wheel is greatly improved.
