| 摘要 | An electromagnetic linear compressor has a linearly reciprocating piston (10) biassed in one direction by a helical coil spring. A rotational bearing (40) supports one end of the spring (20a,20b). To avoid uneven wear due to forces applied by the spring, the spring is replaced by a spring system comprising two helical coil springs (20a,20b) acting in series to bias the piston (10), and the rotational bearing (40) transmits thrust between the two springs while permitting relative rotation of the two springs about their axis. The compressor also has turbine means (30) for exerting a unidirectional rotational force to rotate the piston (10) about its axis gradually during operation of the compressor. | ||||||
