20090070088 | Method and Apparatus fo Computer Modeling Diabetes - The present invention relates generally to a mathematical and computer model of diabetes related disorders (e.g., human type 2 diabetes) within the framework of multiple macronutrient metabolism. The model includes a representation of complex physiological control mechanisms directing, for example, fat metabolism, protein metabolism and/or carbohydrate metabolism. In one embodiment, for example, the model can account for the interconversion between macronutrients, as well as their digestion, absorption, storage, mobilization, and adaptive utilization, as well as the endocrine control of these processes. In this embodiment, the model can simulate, for example, a heterogeneous group of diabetes related disorders, from insulin resistant to severe diabetic, and can predict the likely effects of therapeutic interventions. | 03-12-2009 |

20120318885 | VALVE ASSEMBLY FOR AN INJECTION VALVE AND INJECTION VALVE - A valve assembly for an injection valve may include a valve body comprising a cavity with a fluid inlet portion and a fluid outlet, and a valve needle axially movable in the cavity, the valve needle preventing a fluid flow through the fluid outlet in a closing position and releasing the fluid flow through the fluid outlet in further positions, the valve needle comprising a radially extending protrusion and an electro-magnetic actuator unit configured to actuate the valve needle and comprising an armature in the cavity. The armature comprises an armature cavity having a first stop surface and a second stop surface that faces the first stop surface. The protrusion of the valve needle is arranged in the armature cavity axially between the first stop surface and the second stop surface such that a relative movement between the valve needle and the armature in axial direction is limited. | 12-20-2012 |
20130181070 | Valve Assembly for an Injection Valve and Injection Valve - A valve assembly for an injection valve includes a valve body including a cavity with a fluid inlet portion and a fluid outlet portion, a valve needle axially movable in the cavity, the valve needle preventing a fluid flow through the fluid outlet portion in a closing position and releasing the fluid flow through the fluid outlet portion in a further position, an upper retainer arranged in the cavity and fixed to the valve needle, and an electro-magnetic actuator unit configured to actuate the valve needle, the electro-magnetic actuator unit comprising an armature, arranged in the cavity and axially movable relative to the valve needle, the armature configured to be coupled to the upper retainer when the valve needle is actuated to leave the closing position, and a permanent magnet arranged in the cavity adjacent the position of the armature when the valve needle is in its closing position. | 07-18-2013 |
20140123946 | Injector For Injecting Fluid - An injector for injecting fluid includes a valve needle axially moveable with respect to a valve body and operable to prevent a fluid injection in a closing position and to permit the fluid injection in an open position, an armature for moving the valve needle in a first direction from the closing position towards the open position, a needle retainer fixed to the valve needle, and an armature holder fixed to the armature, wherein the needle retainer and the armature holder are releasably coupleable such that when the armature moves in the first direction the needle is moved in the first direction by the movement of the armature holder and the needle retainer. | 05-08-2014 |
20140166120 | Valve Body, Fluid Injection Valve And Method For Producing A Valve Body - A valve body for a fluid injection valve has a longitudinal axis and includes a base body. The base body has a sidewall defining a recess extending through the base body in an axial direction. The sidewall includes a magnetic material and has at least one opening that perforates the sidewall. The valve body further includes a cover element which includes a non-magnetic material and which is arranged to sealingly cover at least one opening. In addition a fluid injection valve and a method for producing the valve body are disclosed. | 06-19-2014 |
20140352667 | Fluid Injector For a Combustion Engine - A fluid injector for a combustion engine includes a central longitudinal axis, an injection valve housing with an injection valve cavity, a valve needle axially movable within the injection valve cavity, and an electromagnetic actuator unit that actuates the valve needle. The electromagnetic actuator unit includes a pole piece fixedly coupled to the injection valve housing and an armature axially movable within the injection valve cavity and operable to displace the valve needle. The pole piece has a first contact surface and the armature has a second contact surface which are directed opposite each other, wherein one of the two contact surfaces is designed to have a contact angle of less than 90° with a given fluid,and wherein the other of the two contact surfaces is designed to have a contact angle of at least 90° with the given fluid. | 12-04-2014 |
20150040869 | Fluid Injector And Method For Operating A Fluid Injector - A fluid injector includes a valve body, a valve needle and axially moveable in the valve body between a closing position that prevents a fluid injection and further positions that permit the fluid injection, an armature coupled to the valve needle for displacing the valve needle away from the closing position, and a solenoid assembly including at least a first and second coil and operable to magnetically actuate the armature via an electrical signal. A method for operating the fluid injector includes applying the electrical signal to the first coil to generate a magnetic field to move the armature for displacing the valve needle away from the closing position, evaluating a voltage across terminals of the first coil, and controlling the second coil with a further electrical signal to saturate a magnetic field in a portion of the valve body between the armature and solenoid assembly during evaluating the voltage. | 02-12-2015 |
20150069151 | Fluid Injection Valve - A fluid injection valve includes a fluid inlet tube with a recess and a valve body including a central longitudinal axis. The valve body includes a cavity with a fluid outlet portion. The injection valve also includes a valve needle received in the recess and in the cavity. The valve needle is axially displaceable with respect to the fluid inlet tube and the valve body for preventing a fluid flow through the fluid outlet portion in a closing position and releasing the fluid flow through the fluid outlet portion in other positions. The injection valve includes a spring element arranged in the recess and operable to interact with the valve needle for biasing the valve needle in axial direction towards its closing position, wherein the spring element is configured such that a spring stiffness of the spring element depends on a pressure of fluid in the recess. | 03-12-2015 |
