20130283763 | PRESSURE REGULATING VALVE - A pressure regulating valve assembly includes a pressure regulating valve sleeve and a pressure regulating valve spool. The pressure regulating valve sleeve includes a first window set and a second window set. The pressure regulating valve spool includes a first cylindrical portion, a second cylindrical portion, and a third cylindrical portion formed between the first and second cylindrical portions. The pressure regulating valve spool also includes an angled bucket formed on the first cylindrical portion having a high gain portion of a first width, a low gain portion of a second width, and a ratio of the first width to the second width between 1.44 and 1.47. The pressure regulating valve spool further includes an angled outlet surface. The angled bucket is configured to align with the first window set and the angled outlet surface is configured to align with the second window set. | 10-31-2013 |
20140053927 | TURBOMACHINE WINDMILL BYPASS VALVE - An example bypass valve includes a sleeve providing a bore that extends along an axis. The sleeve has at least one window. The bypass valve also includes a spool received within the bore. The spool is configured to move within the bore between a first position that restricts flow through at least one window and a second position that permits flow through the at least one window of the sleeve. An outer diameter of the spool is from 99.90 to 99.95 percent of a diameter of the bore. | 02-27-2014 |
20140075950 | MINIMUM PRESSURE SHUT-OFF VALVE - A minimum pressure shut-off valve closes off fuel flow responsive fuel pressure being below a predefined pressure. A sleeve includes at least a first flow window and a second flow window. The second window includes a notch providing a flow area based on an axial position of a spool moveable within the sleeve. | 03-20-2014 |
20140109979 | Pressure Regulating Valve - In one featured embodiment, a sleeve for a valve includes a sleeve body surrounding a center axis and defined by an overall length extending from a first end to a second end. The sleeve body has a central bore extending from the first end to the second end. The central bore has a first surface portion comprising a piston contact surface that is defined by a first inner diameter, wherein the piston contact surface is configured to slide against a piston to be received within the central bore. In one example, a ratio of the overall length to the first inner diameter is between 3.51 and 3.63. | 04-24-2014 |
20140158227 | PRESSURE REGULATING VALVE - A pressure regulating valve includes a housing having a valve inlet and a valve outlet. A movable piston is located in the housing, and a position of the piston is determined by a selected difference between and inlet pressure and an outlet pressure. The movable piston at least partially defines one or more flow channels between the valve inlet and the valve outlet. When the movable piston is in a fully open position, an axial inlet opening at an inlet end of the one or more flow channels is smaller than an radial depth of the one or more flow channels at the inlet end of the one or more flow channels. | 06-12-2014 |

20090283508 | Method for producting a hole - A method for producing a hole with side-delimiting flanks in a component using a laser beam is provided. A laser beam is directed onto the component. A side flank of the hole is traced with the laser beam. A partial volume of the hole is formed by vaporizing the component material. This is repeated until the whole volume is formed. The laser beam may be oriented so that it includes an angle of more than 8° with the traced side flank. | 11-19-2009 |
20110036819 | Process for Producing a Hole Using Different Laser Positions - Methods for producing a continuous hole in a substrate are provided. A laser is used for producing an inner proportion and a diffuser of the continuous hole, wherein an angular position of the laser with respect to the substrate is changed at least three times. | 02-17-2011 |
20120099978 | Turbine Component Having Easily Removable Protective Layer, Set of Turbine Components, a Turbine and a Method for Protecting a Turbine Component - Turbine components are often shipped individually and are not shipped assembled into a turbine. To this end, the turbine blade has to be protected of external stresses and external damage. This is done by an easily removable protective coating that easily evaporates during the first operation of the newly produced or restored component, so that the protective coating does not have to be removed in an additional operational step before installation. | 04-26-2012 |
20120205355 | Method for producing an asymmetric diffuser using different laser positions - A process for producing a hole with an asymmetrical diffuser is produced. The angular position of the laser with respect to the substrate is changed discontinuously during the processing. The production of complex holes in a substrate is simplified by using a laser in five different angular positions relative to a substrate to be processed. | 08-16-2012 |
