FIELD: engines and pumps.
SUBSTANCE: invention can be used as coolant linear compressor wherein piston oscillates linearly. Linear compressor drive comprises carcass (21, 29, 30) and oscillating body reciprocating in one direction and arranged in aforesaid carcass (21, 29, 30) with the help of at least one membrane spring (8). The latter comprises several branches (14) with one their end interacting with carcass (21, 29, 30) and another end interacting with aforesaid oscillating body (24, 10). Every two branches (14) comprise sections (18, 19) arranged between their ends and having mutually opposite turns.
EFFECT: enlarged stroke of oscillating body that increases flow rate at minor diametre of piston.
