Abstract: A compressor includes a compressor housing defining a cavity, and a compressor wheel disposed in the cavity, the compressor housing defining an inlet for leading air into the compressor wheel, a discharge volute for receiving air compressed by the compressor wheel, and a recirculation duct connected to the inlet at a location upstream of the compressor wheel. A recirculation valve is disposed between the discharge volute and the recirculation duct for regulating air flow through the recirculation duct into the inlet. The recirculation duct defines multiple parallel channels, the multiple parallel channels respectively conducting multiple parallel streams of air from the recirculation valve into the inlet.

Abstract: The subject matter relates to a stylized layer for a cigarette packet, which is developed to fit the packet. It fits the packet recess, enclosing all the rear part and part of the side of the packet, and is provided with a rear wall with a cutout and an internal compartment housing an infrared insert emitting signals in the long infrared. The long-infrared insert has substances that allow a reduction in the level of nicotine and of various other elements harmful to the user's health, found in cigarettes. The user can stylize the packet, since the layer is able to receive promotional messages and be decorated. It allows the control of the substances entering the body, making it possible for the user, to give up smoking. The longer the time of contact between the layer and the packet, the more the level of nicotine and substances in cigarettes will diminish.
