METHOD OF FLOW CONTROL AT INLET OF COMPRESSOR SYSTEM COMPRESSOR (OPTIONS) AND INTERNAL COMBUSTION ENGINE TURBOCHARGER SYSTEM

摘要

1. A method of controlling flow at an inlet of a compressor of a compression system, comprising: directing air from a high pressure source to an inlet upstream of a compressor impeller through a pipeline connected to an inlet and a high pressure source, the pipeline being obliquely connected to the inlet. 2. The method of claim 1, wherein the compression system is a turbocharger or engine supercharger system. The method of claim 1, wherein the conduit is connected to the inlet tangentially to the circumference of the inlet connected to the compressor. The method of claim 1, wherein the conduit is connected to the inlet perpendicular to the circumference of the inlet connected to the compressor. The method of claim 1, wherein the pipeline is connected to the inlet at a predetermined angle from the central axis of the compressor. The method of claim 5, wherein the predetermined angle is greater than the compressor blade angle of the compressor impeller from the central axis of the compressor impeller. The method of claim 1, wherein the air is fresh air without exhaust gases. The method of claim 1, further comprising the step of adjusting the amount of air directed from the outlet to the inlet through a valve located in the line between the high pressure source and the inlet. The method according to claim 8, which includes the step of controlling the amount of air directed from the high pressure source to the inlet through the valve based on the operating condition of the engine. The method according to claim 1, further comprising the step of adjusting the amount of air directed from the high pressure source to the inlet through an opening located
