FIELD: refrigeration and freezing equipment, particularly for coolant compression. ^ SUBSTANCE: cooling device comprises linear compressor module with reciprocating magnet moving in alternating electromagnetic field. Magnet provides movable piston 7 sliding inside cylinder 9. Capsule 1 encloses cylinder 9 and defines buffer volume 24. Cylinder 9 is arranged inside capsule 1 so that cylinder 9 may perform oscillation movement. Inlet orifice 13 of cylinder 9 and inlet pipe 12 of capsule 1 are opposite one to another and are out of contact with each other to create conduit 23 communicated with buffer volume 24. Throttle member 20, 21 is installed in conduit 23. ^ EFFECT: decreased noise generation due to throat modulation. ^ 10 cl, 3 dwg |
