20110296723 | Ironing Appliance Comprising a Piezoelectric Pump - Provided is an ironing appliance, including a pump that has a pumping chamber provided with an inlet and an outlet, the pumping chamber including a movable wall having an outer surface contacting a piezoelectric actuator provided to move the movable wall while changing the volume of the pumping chamber by the piezoelectric actuator, wherein the pump is placed in the ironing appliance such that the outlet of the pumping chamber is located at a higher level than the inlet in a normal position for operating the appliance. | 12-08-2011 |
20110296722 | Piezoelectric Pump for Household Electric Appliance - Piezoelectric pump for a household electric appliance having a moving wall interposed between a first casing element defining a pumping chamber with the moving wall, and a second casing element applying pressure to the periphery of the moving wall in order to hold the latter in position. The moving wall has an exterior face in contact with a piezoelectric actuator designed to cause the moving wall to move so as to bring about a periodic variation in the volume of the pumping chamber under the action of the piezoelectric actuator wherein the first casing element and the second casing element are held together under stress by an elastic clip, the elastic clip applying a pressure that tends to compress the first casing element onto the second casing element. | 12-08-2011 |
