Linear compressor
A linear compressor is a gas compressor where the piston moves along a linear track to compress to minimize energy loss during conversion.
History
The first linear compressors were developed in 1973, the first market introduction of a linear compressor to compress refrigerant was in 2001[1][2]
Valved linear compressor
The single piston linear compressor uses dynamic counterbalancing, where an auxiliary movable mass is flexibly attached to a movable piston assembly and to the stationary compressor casing using auxiliary mechanical springs with zero vibration export at minimum electrical power and current consumed by the motor[3]. It is used in cryogenics .
