1. A compressor comprising:
a shell assembly;
a first compression member rotatable relative to the shell assembly about a first axis;
a bearing housing coupled to the first compression member and rotatable relative to the shell assembly about the first axis, the bearing housing including a plurality of pins extending therefrom; and
a second compression member rotatable relative to the shell assembly about a second axis that is spaced apart from the first axis, the second compression member cooperates with the first compression member to define fluid pockets, the second compression member including a base plate and a plurality of pin pockets, the pin pockets formed in the base plate and receiving the pins, wherein each of the pin pockets includes a working surface that engages and disengages a respective one of the pins,
wherein at a given time during operation of the compressor, a first pin of the plurality of pins engages the working surface of its respective pin pocket and a second pin of the plurality of pins is disengaged from the working surface of its respective pin pocket to allow relative radial movement between the first axis and the second axis.
