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
A linear compressor powered by a free-piston engine was patented by Raúl Pateras Pescara in 1927, US1615133, published Jan 18, 1927.[1] The first market introduction of a linear compressor to compress refrigerant in a refrigerator was in 2001.[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.[4]
Linear compressors are used in LG and Kenmore refrigerators. Compressors of this type have less noise, longer life, and are more energy efficient than conventional refrigerator compressors. [5]
