In a second open position, the piston is spaced apart from the vanes, thereby increasing the input nozzle cross-section.Type: ApplicationFiled: April 28, 2003Publication date: February 12, 2004Inventors: Jean-Luc Hubert Perrin, Olivier Espasa, Marylene Ruffinoni, Alain Lombard, Philippe Joseph Muller

Patent number: 6554568Abstract: In an exhaust turbocharger for an internal combustion engine including a turbine and a compressor, which is driven by the turbine, wherein the compressor comprises a compressor impeller in a flow duct, a transfer component with flow passages extends radially around the compressor impeller in the axial direction of the impeller and provides for communication with the flow duct. To provide for variable adjustment of the effective flow cross-section of the transfer duct, a transfer ring is provided which comprises two component rings, which are rotatable relative to one another.Type: GrantFiled: June 15, 2001Date of Patent: April 29, 2003Assignee: DaimlerChrysler AGInventors: Peter Fledersbacher, Siegfried Sumser, Helmut Finger

Publication number: 20030035720Abstract: The invention relates to a valve arrangement (1), in particular for a power plant. A housing (2) contains a shut-off valve (3) for shutting off a fluid flow, a control valve (4) for controlling the fluid flow through a housing outlet (8) and a bypass valve (5) for controlling the fluid flow through a bypass (13). This bypass (13) branches off from the housing (2) between the shut-off valve (3) and the control valve (4).Type: ApplicationFiled: March 29, 2002Publication date: February 20, 2003Inventors: Ralf Gerdes, Roger Padfield, Franz Suter

Patent number: 6461104Abstract: A flow regulator for a water pump, comprising a control valve. The control valve is mounted on an inlet pipe of a water pump and has a chamber, housing a flat-shaped control plate, the upper part of which forms a piston plate, vertically gliding in an upper chamber. The upper chamber is connected with an outlet pipe. The control valve is exposed to water pressure in the outlet pipe, with the control plate driven downward by the water pressure, countered by two springs at two lateral sides of the control plate. The control plate thus has a varying vertical position according to the water pressure.Type: GrantFiled: June 23, 2001Date of Patent: October 8, 2002Inventor: Der-Fan Shen

Patent number: 6443696Abstract: An exhaust-gas turbocharger turbine of an internal combustion engine is provided with a spiral guide passage arranged in a turbine housing, a turbine impeller, a flow gap be ween the guide passage and the turbine impeller, and guide blades forming a guide cascade. The guide cascade with the guide blades projects axially from a support, arranged so as to be displaceable in the axial direction in the turbine housing, in such a way that the guide blades, in normal operation, are mounted in recesses of a housing wall part of the turbine housing, the recesses, in the form of a female piece, forming a mating profile shape for the guide blades. In braking operation of the internal combustion engine, the guide blades project into the flow gap during an axial displacement of the support. The device with actuation for the braking operation can be fitted as a complete module into the turbine spiral.Type: GrantFiled: October 12, 2000Date of Patent: September 3, 2002Assignee: DaimlerChrysler AGInventors: Wolfgang Erdmann, Carsten Funke, Thomas Hardt, Paul Löffler, Erwin Schmidt, Siegfried Sumser

Patent number: 6401563Abstract: A linkage mechanism for linking for example actuator rods to the nozzle ring of a variable geometry turbine. First and second components of the mechanism are interconnected by at least two links which are displaceable in a predetermined direction relative to the first component and connected at spaced apart locations to the second component. At least one of the links incorporates an element which is pivotal relative to the first component about a first axes and pivotal relative to the second component about a second axis, the two axis being parallel to each other, parallel to the predetermined direction, and offset relative to each other.Type: GrantFiled: June 4, 1999Date of Patent: June 11, 2002Assignee: Holset Engineering Company, Ltd.Inventor: Philip C.

Patent number: 6350101Abstract: The barrel pump has a tubular pump housing and a rotor shaft which is supported by a support tube and, at its bottom end, bears an elastic cone which has a circumferential groove which interacts with the opening edge of an inlet in the manner of a snap-action closure when the rotor shaft is displaced in the direction of incoming flow with respect to the pump housing. The cone seal is situated in front of the inlet, as seen in the direction of flow. To displace the rotor shaft with respect to the pump housing, a rotary cap is provided above the outlet, pins of which cap engage in grooves of a groove flange which is screwed onto the pump housing, the grooves having a pitch, so that as a result of the rotary cap being turned relative displacement between rotor shaft and pump housing is brought about.Type: GrantFiled: August 14, 2000Date of Patent: February 26, 2002Assignee: Lutz-Pumpen GmbH & Co. KGInventors: Volker Fertig, Thomas Sigel

Patent number: 6302644Abstract: Steam turbines with or without a control stage are constructed with the same number of control valves. There are preferably two control valves in each case. The valve subassembly, the turbine outer casing and parts of the turbine inner casing are of identical design and can be used for steam turbines with or without a control stage. In the case of the steam turbine illustrated with a control stage, the inner casing is provided with integrated nozzle boxes, which are separated from each other by intermediate walls. In the case of a steam turbine without a control stage, the nozzle boxes, and accordingly, also the intermediate walls are missing.Type: GrantFiled: February 1, 2000Date of Patent: October 16, 2001Assignee: ABB Alstom Power (Schweiz) AGInventors: Ivan Kukalj, Franz Suter
