Abstract

A linear compressor including: a cylinder part, a piston part, a main spring connecting between said cylinder part and said piston part and operating in the direction of reciprocation of said piston part relative to said cylinder part, a sealed housing, a linear electric motor arranged for operation between said cylinder part and said piston part, a cylinder part spring means connecting between said cylinder part and said housing part and operating in said direction of reciprocation, and a piston part spring means connecting between said piston part and said housing and operating elastically in said direction of reciprocation, said piston part spring means having a spring constant which is the product of the fraction of said piston part mass to said cylinder part mass and the effective spring constant of said cylinder part spring means acting in said direction of reciprocation.
