Claim:
A compressor comprising: a closed vessel; a compression element disposed in the closed vessel, the compression element including a cylinder, an end plate member attached to an open end of the cylinder to form at least one cylinder chamber with the cylinder, a first muffler cover attached to the end plate member on an opposite side from the cylinder to form a space in fluid communication with the cylinder chamber through the end plate member, and a second muffler cover attached to an opposite side of the first muffler cover from the end plate member to form a muffler chamber that is in fluid communication with the space through the first muffler cover; and a motor disposed in the closed vessel to drive the compression element via a shaft, wherein a suction pipe attached to a suction mouth of the closed vessel to provide refrigerant gas, the cylinder chamber being arranged to compress refrigerant gas sucked into the compression chamber from the suction mouth and the muffler chamber being configured to reduce pulsation of compressed refrigerant gas discharged from the cylinder chamber, the muffler chamber having at least one inlet hole portion that receives the compressed refrigerant gas from the compression element into the muffler chamber and a plurality of outlets that discharge the compressed refrigerant gas from the muffler chamber into the closed vessel, and in an orthogonal projection to a plane that is perpendicular to a central axis of the closed vessel and passes through a center of a portion of the suction pipe located in a vicinity of the suction mouth, a direction connecting an arbitrary pair of the outlets coincides with neither a first direction nor a second direction, the first direction being parallel to a central axis of the portion of the suction pipe located in the vicinity of the suction mouth and the second direction being perpendicular to the first direction.
