A linear compressor is a gas compressor where the piston moves along a linear track to compress to minimize energy loss during conversion.
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. It is used in cryogenics.
Linear compressors are use in LG and Kenmore refrigerators. These type of compressors have less noise, longer life, and are more energy efficient than conventional refrigerator compressors.
