  • Publication number: 20190085717
    Abstract: A turbocharger including a pivoting vane (50) aligned with a volute slot (25) of the housing (10) and located proximal a downstream end (57) of a tongue (15) defining an initial inlet throat area (11) of the housing. When the vane is in its fully closed position (60), inlet exhaust gas is prevented from flowing into the volute slot and, therefore, the turbine wheel, until the inlet exhaust gas passes a downstream end (57) of the vane. The vane effectively extends the inlet throat area to define a revised inlet throat area (12). The A/R ratio of the housing progressively varies as the vane pivots between the fully opened and fully closed positions.

  • Patent number: 10132190
    Abstract: An improvement to a turbocharger having a housing (10) with a slot (25) located along a mid-line of the housing (10) above the turbine wheel (29) and a tongue (15) defining the end of an initial inlet throat area (11) of the housing (10), the slot (25) permitting inlet exhaust gas which flows past the tongue (15) to flow into the turbine wheel (29), the improvement being a pivoting vane (50) aligned with the slot (25) and having an upstream end (55) located at a downstream end (57) of the tongue (15). When the vane (50) is in its fully closed position (60), the inlet exhaust gas is prevented from flowing into the slot (25) and, therefore, the turbine wheel (29), until the inlet exhaust gas passes the downstream end (57) of the vane (50). The vane (50) effectively extends the tongue (15) to define a revised inlet throat area (12). The A/R ratio of the housing (10) progressively varies as the vane (50) pivots between the fully opened (70) and fully closed (60) positions.

  • Patent number: 7481056
    Abstract: An exhaust gas turbocharger for an internal combustion engine has a flow control gate that is timely pivotal and located within the exhaust gas inlet downstream of the flow splitter. Control is provided to timely pivot the flow control gate toward the turbine rotor and thus provides an initial high velocity spin to the rotor when turbo charged boost pressure is demanded from an adjustable direction flow control valve. The control valve uses boost pressure from the compressor to timely actuate a piston and lever connected to the pivotal flow control gate, or a signal from an engine control module (ECM) can be directed to a hydraulic, pneumatic or electrical actuator having a reciprocal control rod connected to the flow control gate.

  • Publication number: 20070227142
    Abstract: An exhaust gas turbocharger for an internal combustion engine has a volute or spiral turbine housing and a compressor housing where a turbine rotor and a compressor impeller are connected with one another by a common shaft. The exhaust gas inlet to the turbine housing has a fixed flow splitter. A pivotal flow control gate is attached to the downstream end of the fixed flow splitter. Control means is provided to timely pivot the pivotal flow control gate toward the turbine rotor and thus provide an initial high velocity spin to the rotor when turbo charged boost pressure is demanded. An adjustable directional flow control valve uses boost pressure from the compressor to timely actuate a piston and lever connected to the pivotal flow control gate or a signal from an engine control module (ECM) can be directed to an hydraulic, pneumatic or electrical actuator having a reciprocatable control rod connected to the flow control gate.
