Abstract
A displaceable nozzle (8) of an injection steam generator for small appliances, particularly irons or ironing stations, comprising a steam chamber (3) inside a steam generator housing (1) provided with an injection opening (5), is positioned telescopically on a fixed member to define a nozzle chamber (10). This nozzle (8) can be displaced by an inside pressure in the nozzle chamber in a first pressure range in the direction of the injection opening (5) and can be moved back from the injection opening (5) by a restoring force e.g., a restoring spring (12), wherein the inside pressure in the nozzle chamber (10) is lower in second pressure range than in the first pressure range. A drain passage (18) for the nozzle chamber 10 is connected via a valve arrangement (19, 21) to the fixed member (11), so that excess residual water, which exits when the nozzle (18) is moved back from the nozzle chamber (10), does not cause calcification of the nozzle opening (9) and the injection opening (5). The valve arrangement (19, 21) closes off the drain passage (18) in the first pressure range and opens it in the second pressure range.
