20100284832 | REGULATABLE COOLANT PUMP - The invention relates to a controllable coolant pump driven by a belt pulley for internal combustion engines. The aim of the invention is to develop a controllable coolant pump (having a gate valve) driven by a belt pulley, allowing significant reduction in both pollutant emissions and frictional losses and fuel consumption over the entire working range of the engine, and allowing reliable actuation of the gate valve with very low drive power, even under unfavorable thermal boundary conditions, such as in proximity of the turbocharger, as well as under very limited installation space, and ensuring continued functioning of the coolant pump (fail-safe) even if the controller fails, and characterized by a very simple, low-cost production and assembly design “standardized” for different pump sizes, thereby ensuring continuously high operational reliability at a high volumetric efficiency, and requiring no air-free charging in the factory, and that can be simply and inexpensively integrated in the engine management system. The controllable coolant pump according to the invention, having a gate valve and driven by a belt pulley ( | 11-11-2010 |

20100021282 | Side-Channel Pump - A side-channel pump for pumping a medium by means of an impeller having a ring of rotor chambers, comprising pockets in a radially outer region delimited by the rotor chambers. The pockets are filled by means of leakage with the medium to be pumped and create an axial force on the impeller. Therefore, the impeller is reliably held in the side-channel pump. | 01-28-2010 |
20120003083 | Side Channel Pump for Conveying Fuel in a Motor Vehicle - A side channel pump for conveying fuel having a flow divider disposed in an impeller. The flow divider divides blade chambers of the impeller into individual partial chambers. Flow dividers are also disposed in housing parts opposing the impeller having partial ring-shaped channels radially encompassing each other. The flow dividers in the impeller and in the housing parts are at a distance from each other in order to allow cross flow between the conveyance chambers formed by the partial chambers and the partial ring-shaped channels. The side channel pump thereby has a high efficiency and particularly low radial dimensions. | 01-05-2012 |

20100162564 | METHOD FOR MACHINING A GAS TURBINE ROTOR - A method for machining a gas turbine rotor which is provided with a cooling air slot which concentrically extends around the axis of the gas turbine rotor and is supplied with compressed cooling air via axial cooling air holes which at the side lead into the slot base of the cooling air slot, and the opening of which is covered by bridges which are arranged in a distributed manner over the circumference and spaced apart from each other by gaps. A crack-resistant slot shape is achieved without intervention into the configuration of the bridges by a material-removing tool, particularly a milling tool, being lowered in the gaps between the bridges one after the other into the cooling air slot and in this way the slot base of the cooling air slot being machined and widened over the entire circumference. | 07-01-2010 |
