ABSTRACT:
In a sliding-vane rotary compressor, one of the opposite open ends of a cylinder is closed by a first head, the other open end being closed by a side block to which is secured a second head so as to define jointly with the side block a low pressure chamber and a high pressure chamber. With this construction, one side block can be omitted and hence the number of structural components is reduced. Preferably, a displacement adjustment mechanism is incorporated in the side block and the second head for adjusting the displacement of the compressor.
