Compressor in induction tract of internal combustion engine has blocking element that acts on spin device at auxiliary channel opening so blocking element control movement displaces spin device

摘要

The device has a rotatable compressor wheel in a compressor inlet channel that compresses combustion air to an increased charge pressure, an auxiliary channel opening into the compressor inlet channel, an adjustable blocking element in the inlet channel upstream of the wheel and an adjustable spin device in the opening region of the auxiliary channel. A control movement of the blocking element causes a displacement of the spin device. The device has a rotatable compressor wheel (2) mounted in a compressor inlet channel (5) that compresses combustion air to an increased charge pressure, an auxiliary channel (15) opening into the compressor inlet channel, an adjustable blocking element (9) in the compressor inlet channel upstream of the compressor wheel and an adjustable spin device (14,17) in the opening region (16) of the auxiliary channel. The blocking element acts on the spin device so a control movement of the blocking element causes a displacement of the spin device. AN Independent claim is also included for the following: (a) an exhaust gas turbocharger with an inventive compressor.
