| 20080240942 | Diaphragm pump for pumping a fluid - A diaphragm pump for pumping a fluid, includes a flexible diaphragm which contains magnetically hard or soft particles and is actuated by an electromagnetic actuator. The diaphragm pump having a housing having an interior space containing two pump chambers which are separated by the diaphragm, and in that the diaphragm is actuated by two opposite electromagnetic actuators. | 10-02-2008 |
| 20080265195 | Flow connector for a valve - A flow connector for a valve, including a body in which a flow channel is formed that is made up of a first port, a second port and an opening area to receive a movable plug, whereby the ports can be flow-connected through the opening area. An objective of the present invention is to configure and refine a valve having a flow connector in such a way that the volume of fluid that flows through the flow channel per unit of time can be set without any problem wherein the cross section surface area of the flow channel in the opening area is configured to be constant along a first height of lift and to be variable along a second height of lift. A solenoid valve includes the flow connector according to an embodiment of the present invention. | 10-30-2008 |
| 20090057587 | Valve with magnetic sealing element made of foam - A valve is described having an inlet, an outlet, a sealing element and a device to generate a magnetic field, whereby the sealing element can be moved at least partially by the device and whereby the sealing element connects the inlet to the outlet in a fluid-conducting manner in that the sealing element lifts off at least partially from a valve seat wherein the sealing element is made at least partially of a foam element that can be deformed by the magnetic field. | 03-05-2009 |
| 20110006239 | PREASSEMBLED VALVE ASSEMBLY FOR USE IN A TURBOCHARGER - A valve assembly disposable in a turbocharger housing includes a cover; a sealing body connected to the cover so as to form a pressure space between the cover and the sealing body; a restoring spring disposed in the pressure space and disposed against the cover and the sealing body, wherein the sealing body is moveable relative to the cover counter to the force of the restoring spring; and a diaphragm connecting the cover and the sealing body to each other, wherein the diaphragm at least partly surrounds the sealing body. | 01-13-2011 |
| 20110203691 | NON-RETURN VALVE - A non-return valve includes a valve housing having at least one inlet, at least one outlet, a first valve seat and a second valve seat; and an at least partially flexible sealing member forceable into a scaling engagement with the first valve seat in response to a first differential pressure and forceable into a sealing engagement with the second valve seat in response to a second differential pressure. | 08-25-2011 |
