Title: Structure for reducing noise of rotary compressor
Inventor: AHN BYUNG HA
IPC: F04C29/06
Filed: 1998-12-17
Abstract: PURPOSE: A structure for reducing noises of a rotary compressor is provided to embody the low-noise operation structure by forming a coolant gas vent hole between a hole of a muffler and a boss unit of a main bearing. CONSTITUTION: Coolant gas flowed in through a vent passage(64b') of a main bearing flows toward the outside of a muffler(70') by an inertia force and speed energy. After the coolant gas consumes a certain degree of the speed energy while flowing, the coolant gas is discharged through a muffler vent hole while flowing in a central direction of the muffler. Herein, the coolant gas is discharged in a state that the speed energy and the inertia force are weakened to a certain degree. Accordingly, since the coolant gas is vented into a hermetic case through the muffler vent hole in a state that pressure pulsation and energy are reduced, the noises are reduced.
