Linear compressor

一种线性压缩机，包括外壳；设置在外壳内的驱动单元；由驱动单元驱动压缩制冷剂的压缩单元；弹性支撑压缩单元的支撑弹簧；从压缩单元和外壳内顶部中的一个伸出的凸起；以及设置在压缩单元和外壳内顶部中的另一个中且在预定的可动范围内可动地容纳所述凸起的停止件。采用这种结构，线性压缩机能够防止压缩单元与外壳内表面之间的碰撞。 A linear compressor including a casing, a driving unit provided within the casing, a compressing unit driven by the driving unit, compressing refrigerant, and a supporting spring elastically supporting the compressing unit, a projection projecting from on one of the compressing unit and a ceiling part of the casing, and a stopper provided in a remaining one thereof, movably accommodating the projection within a predetermined movable range. With this configuration, the linear compressor is capable of preventing a collision between a compressing unit and an inner face of a casing.
