Abstract: A linear compressor has a rigid frame (11, 12, 13), on which an oscillating body (16) is held via at least one spring (9) so as to be able to effect reciprocating motion and at least one electromagnet (14, 15) is mounted for driving the reciprocating motion of the oscillating body (16), and having a pump chamber (13) forming part of the frame, in which pump chamber a piston, connected to the oscillating body (16), may effect reciprocating motion. The frame (11, 12, 13) is connected in an oscillatory manner to a fixing member (1) for fixing the linear compressor to a support by a diaphragm spring (5, 7, 9) oriented transversely of the direction of movement of the oscillating body.

Abstract: A compressor housing comprising an upper shell and a lower shell assembled at a peripheral weld seam. At least one shell extends from the center of the housing beyond the weld seam outwards and upwards.

Abstract: A compressor for a refrigeration device comprising a compartment, a piston which can be displaced inside the compartment, and valves which are arranged between the compartment and a suction connection or a pressure connection. The movable parts of the valves are provided with a coating that is harder than the movable parts.

Abstract: A drive unit for a linear compressor comprising a frame and an oscillating body. The oscillating body is mounted in the frame via at least one diaphragm spring and can be moved back and forth in one direction. The diaphragm spring comprises a plurality of limbs, fastened with one end to the frame and with the other end to the oscillating body. Two limbs each have inversely curved sections between the two ends.

Abstract: A linear compressor comprising a pump chamber wherein a moves reciprocatingly, a frame which is integral with the pump chamber and against which a floating body is reciprocatingly maintained by at least one spring, at least one electromagnet mounted on the frame for causing the reciprocating movement of the floating body. A translation rod is connected to the piston through a first articulation and to the floating body through a second articulation.

Abstract: A drive unit for a linear compressor comprising a frame and an oscillating body. The oscillating body is mounted in the frame via at least one diaphragm spring and can be moved back and forth in one direction. The diaphragm spring comprises a plurality of limbs, fastened with one end to the frame and with the other end to the oscillating body, which are associated with respective readjusting springs that counteract a deformation of the arm.

Abstract: A linear compressor comprising a cylinder, a hydraulically borne piston that can be longitudinally oscillated inside the cylinder, and a drive unit driving the movement of the piston. The compressor is characterized in that at least one of the lateral faces of the piston and the cylinder that face each other is provided with an abrasion-resistant bearing coating.

Abstract: A linear compressor with a pumping chamber, in which a piston moves back and forth, and a frame, fixed to the pumping chamber, on which an oscillating body, connected to the piston, is fixed by at least one spring such as to move back and forth and provided with at least one electromagnet, for driving the back and forth movement of the oscillating body. A one-piece spring connects the oscillating body to the frame and the frame to a fixing body, for fixing the linear compressor to a support.

Abstract: A household appliance comprising a body and a door which surround an interior, and a light source for illuminating the interior. The inventive household appliance further comprises a door opening sensor for detecting the open or closed state of the door and adjusting the mode of operation of the light source based on the detected state of the door. The door opening sensor encompasses a light sensor which is exposed to ambient light when the door is open while being isolated from said ambient light when the door is closed.
