Abstract: The fuel injector including an orifice plate which is provided with a multitude of outlet openings and situated downstream from a valve-seat body having a fixed valve seat. Directly upstream from the outlet openings is an inflow opening having an annular inflow cavity. The valve-seat body covers the inflow cavity in such a way that the downstream outlet openings of the orifice plate are covered. The outlet openings each have an inflow region whose diameter D1 is considerably larger than the diameter D2 of a region that abuts at a sharp angle directly downstream therefrom, which forms the narrowest cross section of the outlet opening and from where the outlet opening widens in the flow direction to a diameter D3 in a trumpet-shaped manner. The fuel injector may be particularly suitable for use in fuel injection systems of mixture-compressing ignition engines having externally supplied ignition.

Abstract: An evaporator defines an evaporator volume, and boils the liquid inside evaporator volume. A mixing chamber is in communication with the evaporator volume and mixes the vapor or moisture from the liquid in the evaporator with the breathing gas of the patient. The mixing chamber is a separate structure than the evaporator. The mixing chamber and the evaporator are connected by a first connection that is repetitively connectable and disconnectable without significant destruction of a respective connection. A heater is arranged outside of the evaporator and in a heat conducting connection with the evaporator. The heater is a separate structure than the evaporator. The evaporator and the heater are connected by a second connection that is repetitively connectable and disconnectable. A liquid storage tank is in communication with the evaporator and supplies a liquid to the evaporator through a flow channel. The liquid storage tank is larger than the evaporator.

Abstract: An arrangement for pouring a pourable melt made up of a copper alloy, which comprises a melting furnace, pivotable about a horizontal pivot axis, having a pouring tube which discharges pourable melt and through which the pourable melt can be conveyed under a shielding gas atmosphere to a filling end of a launder and can be conveyed through an outlet of the launder to a mold. The filling end of the launder is coverable by a hood that seals off the pourable melt from the atmosphere, the pouring tube engaging, with interposition of a seal arrangement, in pivotably movable fashion into the hood. As a result, the pourable melt can be transferred into the launder under a shielding gas atmosphere upon pivoting of the melting furnace and the pouring tub.
