Abstract

A rotary piston compressor, particularly Root's type compressor, includes a housing which is made of only two portions, one of which is cut-shaped and accommodates pistons rotating in opposite directions, and the other of which is formed as a cover closing the end face of the first portion. The two portions are connected to each other and positioned relative to each so that they abut each other along a separation plane which extends centrally of a suction connection and a pressure connection formed on the housing diametrically opposed relative to each other.
