Patent number: 7654106Abstract: A no-frost refrigerator having an opening in a separating wall for the through passage of air between a storage chamber and an evaporation chamber. A control element is arranged in the opening and can be displaced or shifted between positions in which the control element covers the opening to different extents. The control element can be rotated about an axis substantially perpendicular to an axis or plane of the air passage opening.Type: GrantFiled: October 16, 2003Date of Patent: February 2, 2010Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Rolf Kordon, Renate Pradel

Publication number: 20070051416Abstract: A multiway valve contains a housing having several inlets and outlets and a chamber. Several seats are provided and each is respectively associated with one inlet or one outlet. A closure element is provided which can move between the seats and at least one actuator is provided in the form of an element made of a form memory alloy, able to displace the closure element from one of the seats when heating occurs. A spring element presses the closure element against each respective seat that it engages.Type: ApplicationFiled: November 9, 2006Publication date: March 8, 2007Applicant: BSH Bosch und Siemens Hausgerate GmbHInventors: Hans-Frieder Eberhardt, Rolf Kordon, Michael Neumann, Udo Wenning

Patent number: 7093462Abstract: A multi-way valve, particularly for a refrigerant circuit, includes a housing having a number of inlets and outlets and a chamber with a number of seats respectively associated with an inlet or outlet. The multi-way valve also includes a closing element that can move between the seats and at least one actuator, which is provided in the form of an element made of a shape-memory alloy and capable of being displaced from one of the seats when the closing element is heated. The direction of displacement is transversal to the normal direction of the seat.Type: GrantFiled: June 21, 2004Date of Patent: August 22, 2006Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Hans-Frieder Eberhardt, Rolf Kordon, Michael Neumann, Udo Wenning

Patent number: 6899135Abstract: A housing of a multiway valve contains several inlets and outlets and a chamber containing several valve seats, each of which is allocated to one of the outlets. A closing device can be displaced between the valve seats. A cylinder contains a cylinder chamber having a fluid. A heating device is provided for heating the fluid and a plunger is provided that can be displaced in the cylinder by the pressure of the fluid. By its displacement, the plunger is able to dislodge the closing device from one of the valve seats.Type: GrantFiled: June 21, 2004Date of Patent: May 31, 2005Assignee: BSH Bosch und Siemens Hausgeräte GmbHInventors: Hans-Frieder Eberhardt, Rolf Kordon, Michael Neumann, Udo Wenning
