Abstract: A device for controlling the output of rotary compressors which includes a housing (8) formed of two housing parts which define connection flanges (1, 3) at opposite ends thereof and which define a dividing plane (13) therebetween that is slanted toward the plane of the connection flanges (1, 3) on both sides between a regulating flap valve (4), which controllably changes the passage cross-section of the suction duct, and a check valve (7) that is arranged behind the flap check valve in the direction of flow. The housing (8) may be assembled in different relative positions of the two housing parts (14, 15), which makes manufacturing simpler and more cost-effective and makes possible different relative positions of the two connection flanges (1, 3) to one another.
