The turbine includes a turbine rotor having turbine blades; a turbine housing accommodating the turbine rotor 80 and whose cross-sectional area of a scroll portion formed between the turbine housing and the turbine rotor gradually decreases; a plurality of fixed vanes fixed along a curved line dividing the scroll portion into an inner scroll part and an outer scroll part; throats formed between the adjacent fixed vanes and communicate between the inner scroll part and the outer scroll part; and a switch valve which switches a flow path in the turbine housing either to the inner scroll part or to both the inner scroll part and the outer scroll part, in which flow path areas of the throats are reduced in a downstream direction of the scroll portion.Type: GrantFiled: November 26, 2008Date of Patent: July 24, 2012Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Atsushi Matsuo, Takao Yokoyama, Motoki Ebisu

Patent number: 8221058Abstract: The present invention relates to a fresh gas system (1) for supplying an internal combustion engine (4) with fresh gas, in particular in a motor vehicle, having a charging device (8) for increasing the pressure of the fresh gas and having a swirl generator (12), which is arranged upstream of the charging device (8), for generating a swirl, which rotates about the main flow direction of the fresh gas, in the fresh gas, wherein the swirl generator (12) has guide blades (14) with adjustable angle of incidence. In order to be able to produce the fresh gas system (4) more cost-effectively, the swirl generator (12) has a flow guide body (13) on which the guide blades (14) are integrally formed and which, in order to adjust the angle of incidence of the guide blades (14), can be twisted with elastic deformation about the main flow direction starting from an undeformed initial position.Type: GrantFiled: May 18, 2007Date of Patent: July 17, 2012Assignee: Mahle International GmbHInventors: Tristan Fleischer, Neil Fraser

Patent number: 8210793Abstract: The invention relates to a radial compressor for a turbocharger (5), in particular for an internal combustion engine, with a compressor wheel (4) for conveying and compressing a gas, which has an axial intake end (7) and a radial exhaust end (8), with a compressor wheel space (3), in which the compressor wheel (4) is arranged and which extends from the intake end (7) to the exhaust end (8), with an inlet port (10) leading to the intake end (7) of the compressor wheel (4), with at least one recirculation path (12) which opens at one end into the inlet port (10) and at the other end into the compressor wheel space (3). To increase the efficiency of the compressor (1) and/or the charger (5) equipped with the compressor, a control device (15) is provided for varying the flow-through cross section, namely at least opening and closing the flow-through cross section, of the at least one recirculation path (12).Type: GrantFiled: July 29, 2008Date of Patent: July 3, 2012Assignee: Bosch Mahle Turbo Systems GmbH & Co. KGInventor: Thomas Hale

Patent number: 8206089Abstract: A flow control device for controlling fluid flow into a turbine comprising a stator and a rotor located in a fluid flow direction downstream of the stator is provided. The stator has a plurality of vanes extending radially inwards from a casing. Nozzles are defined, with each being defined between each adjacent pair of vanes. A flow controller is arranged to control a nozzle area open for fluid flow from a stator to rotor by altering the radial length of at least one of the nozzles and comprises an actuator and baffle plates connected at first ends thereof to a periphery of the turbine and at second ends thereof to arcuate plates of the actuator. Each baffle plate extends through a corresponding nozzle from an upstream to a downstream side of the stator. The actuator may selectively move the baffle plates to adjust flow through the nozzles.Type: GrantFiled: November 30, 2007Date of Patent: June 26, 2012Assignee: Parsons Brinckerhoff LimitedInventors: Paul Michael Willson, George Andrew Atkinson

Patent number: 8202040Abstract: A header body for use in fluid circulation systems such as a hydronic heating system is provided in which the header body is configured to couple fluid flow to individual fluid circuits of the system. In one embodiment, the header body comprises a suction chamber with a fluid passage through which fluid flows as between one or more header bodies coupled together to form a manifold. A valve is disposed in the suction chamber, wherein in one example the valve comprises a valve body that is supported by portions of the suction chamber on opposite sides of the fluid passage. The valve body is configured with an aperture that is aligned with the fluid passage in a first and second operating state, one of which decouples the fluid circuit from the system.Type: GrantFiled: July 1, 2010Date of Patent: June 19, 2012Inventor: Kevin J. Koenig
