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.

No-frost refrigerator

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.

Multiway valve

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.

Multi-way valve and refrigerating machine with multi-way valve

A solenoid valve for a coolant circuit including a valve body having at least one inlet and at least one outlet for the coolant. A valve member is displaceable in the interior of the valve body between two switching positions for the solenoid valve. At least one outlet is formed by a capillary tube.

Solenoid valve for a coolant circuit

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.

A solenoid valve, in particular, for a refrigerating machine, includes a valve body with an inlet and two outlets, a valve element that can be moved in the valve body between two end positions corresponding respectively to different switching positions of the solenoid valve, at least one permanent magnet for holding the valve element in the respectively assumed end position, and a magnet coil for exerting on the valve element a magnetic force effecting a shift into the respective other end position. The valve body and the magnet coil are accommodated in two compartments of a housing, and the at least one permanent magnet is held in a receptacle on a wall of the housing in a fashion facing a middle position of the valve element situated between the two end positions.
