  • Compressor cover assembly method and forming tool
    Patent number: 10233946
    Abstract: A method of assembling and retaining a noise attenuation device (30) within an air inlet (16) of a compressor cover (12) includes inserting the noise attenuation device (30) into the air inlet (16) and applying a rolling compressive force to the air inlet (16) using a forming tool (40). As a result, the air inlet terminal end (17) is deformed radially inward so as to form a radially-inwardly protruding lip (17b) about the air inlet terminal end (17). The radially-inwardly protruding lip (17b) is configured to retain the noise attenuation device (30) within the air inlet (16). The forming tool (40) used to form the radially-inwardly protruding lip (17b) is also described.

  • AXIAL COMPRESSOR WITH A MAGNETIC STEPPER OR SERVO MOTOR
    Publication number: 20160252095
    Abstract: An axial compressor (30) is disposed upstream from a compressor wheel (16), and may be mounted in the inlet pipe (32) of a compressor housing (26) of a turbocharger (10). The axial compressor (30) can increase the pressure ratio approximately 1.3. The axial compressor (30) can be driven by a motor (40), such as a magnetic stepper, servo and squirrel cage motor. The axial compressor may have a fan (34) where boost can be controlled by speed of the fan (34), which can be accelerated or decelerated depending on use conditions. A magnetic stepper motor (40) can drive the fan (34) with a fan wheel (36) having magnets (44) associated with energizeable coils (42) that make a rotating magnetic field that the magnets (44) can follow.
