Abstract:
An injection steam generator for small appliances, said generator comprising a steam chamber disposed within and formed by a steam generator housing that is provided with an injection opening in a sidewall; a displaceable nozzle mounted telescopically on a fixed tubular member, to define a nozzle chamber within said nozzle and said fixed member, for displacement in a first pressure range in a direction toward the injection opening by an internal pressure in the nozzle chamber; a restoring force device for displacing the nozzle in a direction away from the injection opening when the internal pressure in the nozzle chamber is in a second pressure range that is lower than the first pressure range; and means for discharging residual water from the injection steam generator when the nozzle is displaced in a direction away from the injection opening, said means including a drain passage connected via a valve arrangement with the fixed member and in communication with the nozzle chamber for discharging the excessive residual water from the nozzle chamber when the nozzle is displaced away from the injection opening, with the valve arrangement being responsive to the pressure in the nozzle chamber to close the drain passage in the first pressure range and to open the drain passage in the second pressure range.
