  • Patent number: 9970327
    Abstract: The invention relates to a device and a method for separating dirt particles from the working medium of a turbine (10). The turbine (10) comprises at least one rotor (11) which is arranged in a housing (17). A swirl generator (20) is provided that sets the working medium and the dirt particles in a spiral-shaped rotational movement along a principal axis (22) by means of the geometry of the swirl generator (20) and thereby separates the dirt particles from the working medium. The swirl generator (20) is designed in such a way that the working medium experiences a reversal of the speed component parallel to the principal axis (22) within the swirl generator (20).

  • Patent number: 8671912
    Abstract: The invention relates to an injector, in particular, a common-rail injector for injection of fuel into a combustion chamber of an internal combustion engine. An injection valve element, adjustable between a closed position and an open position, is controllable by means of a control valve. The control valve has a control valve element, adjustable between a closed position and an open position by means of an actuator, which in the closed position is an at least almost pressure-equalized and has a sealing line which cooperates in a sealing manner with a control valve seat. The sealing line of the control valve element is lifted off the control valve seat in the open position and hence opens fuel flow from a high pressure region to a low pressure region of the injector. According to the invention, the control valve element has a support region extending over the sealing line in a radial direction to the high pressure region.
