Abstract
A linear compressor for a household appliance, for instance a refrigerator, includes a yoke-magnet-arrangement clamped on a cylinder of a cylinder-piston arrangement in such a way that temperature expansions of the yoke-magnet-arrangement are enabled. In particular, a spring force forces the yoke-magnet-arrangement against a fixed stop of the cylinder. A household appliance having the linear compressor is also provided.
