Abstract: The present invention provides a moisture-generating device (10) for generating a moisture-enriched air flow or gas flow, said device comprising: a housing (H) having an outflow region (3), in at least sections of which a gas flow or air flow can be generated, and having a lateral inlet region (EB), and having a mixing region (MB) which extends inside the housing (H); a water injector (WI) which is located in the lateral inlet region (EB) and by means of which atomized water can be introduced into the mixing region (MB) at the specific angle, wherein, in the mixing region (MB), the gas or air can be mixed with the atomized water; a humidifying grid (BG) which is located in the mixing region (MB) and to which the water injector (WI) is aligned; and a flow generator (SZ) which is located in the housing (H) between the mixing region (MB) and the outflow region (3) and by means of which the air flow or gas flow comprising the atomized water can be delivered to the outflow region (3) and can be generated.

Abstract: The present invention relates to a moisture-generating device (10) for generating a moisture-enriched air flow or gas flow, said device comprising: a housing (H) having a main extension direction (HR) and an inflow region (2) and an outflow region (3), and having a lateral inlet region (EB) which extends at a specified angle to the main extension direction (HR), and having a mixing region (MB), a water injector (WI) which is located in the lateral inlet region (EB) and by means of which atomized water can be introduced into the mixing region (MB) at the specified angle with or counter to the main extension direction (HR); a separator grid (SG) which is located in the mixing region (MB); and a homogenizing region (HB), which adjoins the mixing region (MB) in the main extension direction (HR), and wherein a degree of moisture of at least regions of the gas or air flow in the homogenizing region (HB) can be homogenized.

Abstract: A sealing element of a valve, e.g., a gas valve, for controlling a medium includes a base body having a sealing surface, the sealing surface either (i) being inclined in relation to a center axis of the sealing element or (ii) having at least one inclined area. In addition, a valve seat support of the valve for controlling a medium includes: a first ring-shaped valve seat in a first valve seat plane; a second ring-shaped valve seat in a second valve seat plane; and a passage aperture situated between the first valve seat and the second valve seat, the first and second valve seat planes being perpendicular to a center axis of the valve seat support.

Abstract: A valve for controlling a medium, e.g., a gaseous medium, includes: a valve support having at least one passage aperture; a closing element which is configured to open and to close the at least one passage aperture; and a valve seat including at least one area projecting in the axial direction of the valve, the projecting area being coated with an elastomeric sealing element, and the elastomeric sealing element being exclusively situated on the projecting area of the valve seat.

Abstract: A pressure-effected interconnection of a metal part and a plastic part which is slipped over the metal part with a press fit, in particular in a fuel injector for internal combustion engines, is provided in which, for a reliable connection between the pressing pieces, without high demands on manufacturing tolerances, the outer wall of the metal part has circumferential ribs disposed one behind the other in the axial direction, with a back that rises from the outer wall towards the outside in the slide-on direction of the plastic part, and a flank that falls steeply from the back to the outer wall. Each rib has disposed in front of it—viewed in the slide-on direction of the plastic part—an annular groove, the annular groove being introduced into the outer wall, directly at the foot of the back.

Abstract: A valve for controlling a fluid, in particular for controlling a gas. The valve includes a valve housing having a housing sleeve and an electromagnetic actuator for an armature which is guided in an axially displaceable manner and which cooperates with a valve seat situated on a seating plate so that a fluid flow through outflow orifices in the seating plate is controllable. The armature is guided along an armature sleeve which is situated in the housing sleeve.

Abstract: A fuel injector (1) for the direct injection of fuel into the combustion chamber of an internal combustion engine has a piezoelectric actuator (2) which is encapsulated in an actuator housing (3); a valve needle (9) which is in operative connection with the actuator and on which a valve-closure member (11) is formed which forms a sealing seat together with a valve-seat surface (13); and a nozzle body (12) into which the actuator housing (3) is able to be inserted. The actuator housing (3) and the nozzle body (12) are sealed by a common connecting part (4), the connecting part (4) having a first and a second diameter step (19; 20).
