    • A linear compressor for generating a compressed gas includes two pistons (608a, 608b) and two cylinders (607a, 607b) so disposed coaxially as to face in mutually opposite directions, a shaft (603) equipped with the pistons (608a and 608b) at both ends thereof, coil springs (605a and 605b) coupled to the shaft (603), for returning the pistons moved apart from the piston neutral points to the piston neutral points, and a linear motor (613) for alternately generating compressed gas in two compression chambers (611a and 611b) by reciprocating the shaft (603) in the axial direction. Two non-linear forces exerted on the pistons by the compressed gas are generated and the phases of the forces are opposite. As a result, in comparison with a conventional construction equipped with only one piston, the motor thrust is reduced and converted to a linear thrust, and a high efficiency is achieved. Further, the size of the apparatus and vibration and noise are reduced.
    • 用于产生压缩气体的线性压缩机包括两个活塞(608a,608b)和两个同轴地设置为相互相反的方向设置的气缸(607a,607b),配备有活塞(608a和608b)的轴(603) 其两端连接有与所述轴(603)连接的螺旋弹簧(605a和605b),用于使从所述活塞中性点离开的所述活塞返回到所述活塞中性点;以及线性马达(613),用于交替产生压缩气体 压缩室(611a和611b)通过使轴(603)沿轴向往复运动。 产生由压缩气体施加在活塞上的两个非线性力,力的相位相反。 结果,与仅配备一个活塞的传统结构相比,电动机推力减小并转换成线性推力,实现高效率。 此外,装置的尺寸以及振动和噪声减小。
