  • Patent number: 8522462
    Abstract: 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.

  • Patent number: 8215108
    Abstract: A Control apparatus for a piston/cylinder arrangement, having a valve arrangement connected to a first part space, which assumes a closed position preventing a fluid held in the first part space from flowing out if the pressure in the fluid is smaller than a pressure control value set on the valve arrangement and which assumes an opening position if the pressure in the fluid is greater than the set pressure control value, and having a priming device which is coupled to the valve arrangement and the first part space serving to prepare for the damping of a pressure increase in the fluid which is brought about by a movement of the piston caused by a load acting on the piston in the direction of the first part space such that a pressure increase can be generated in the fluid to a predefined pressure priming value independently of the load.

  • Patent number: 8132289
    Abstract: A locking device for a telescoping pole for use with a retractable handle system, the pole having at least one moveable section slideably mounted in a guide member having at least one opening. The locking device includes a body fixed to the movable section, a locking member carried by the body and movable between locking an unlocking positions, a rotatable lever carried by the body and pivotable between a release position, in which relative movement is permitted between the movable section and the guide member, and a blocking position, in which the lever comes to bear on the guide member and exerts a force assuring a transverse immobilization of the moveable section in the guide member. The lever is coupled to the locking member to be displaced toward the blocking position when the locking member is engaged in the opening under the force produced by a restoring element.
