ABSTRACT:
A device for delivery control is provided in a rotary piston compressor which takes the general form of a housing which is composed of a shell and two parallel side parts and has an outlet duct and at least one lateral inlet duct, and a piston which is mounted on an eccentric of an eccentric shaft, and which in rotation, defines with the inner surface of the shell, working chambers which are variable in volume and which with axial seals located along its circumferential edges, overrides one of the inlet ducts. The improvement of the delivery control device is provided by at least one recess in one side part lying in the direction of rotation of the piston after the inlet duct, a withdrawable plug being disposed within the recess so that it is flush in its closed position with the side wall. When the plug is withdrawn the recess enables one of the working chambers which is in the compression cycle to communicate with the inlet duct through a hollow space provided in the piston during sliding of the axial seals arranged along the circumference of the piston over the recess.
