[2] The sealed compressor according to claim 1,
wherein the hood section is provided with a first projection of a pin shape;
the auxiliary hood has a first through-hole; and
the hood section and the auxiliary hood are fastened together in a state where the first projection is inserted into the first through-hole and a tip end portion of the first projection is deformed.
[3] The sealed compressor according to claim 1 or claim 2,
wherein the suction muffler has a rectangular side wall having long sides and short sides, and the side wall has the opening portion; and

the hood section is provided on the side wall and has a circular-arc shape when viewed from a direction in which the hood section extends.
[4] The sealed compressor according to claim 2 or claim 3, further comprising:
a binder having a through-hole;
wherein the hood section, the auxiliary hood, and the binder are joined together in this order; and
the hood section, the auxiliary hood, and the binder are fastened together in a state where the first projection is inserted into the first through-hole of the auxiliary hood and into the through-hole of the binder, and a tip end portion of the first projection is deformed.
[5] The sealed compressor according to claim 4,
wherein the binder and the first projection of the hood section are made of the same material.
[6] The sealed compressor according to any one of claims 1 to5,
wherein the auxiliary hood has a press section for receiving a pressure of the cooling medium gas discharged from the suction pipe.
[7] The sealed compressor according to claim 6,
wherein the auxiliary hood has a circular-arc portion having a circular-arc shape;
the press section includes a connecting portion connecting both ends of the circular-arc portions together, at least a portion of the connecting portion being configured to contact the side wall of the suction muffler; and a cover portion provided on the connecting portion and configured to contact a front side wall adjacent to the side wall of the suction muffler.
[8] The sealed compressor according to claim 7, further comprising:
a second projection of a pin shape provided on the front side wall of the suction muffler which contacts the cover portion of the auxiliary hood;
wherein the cover portion of the auxiliary hood has a second through-hole into

which the second projection is fitted.
[9] The sealed compressor according to claim 8,
wherein the front side wall of the suction muffler which contacts the cover portion of the auxiliary hood has a recess to accommodate the cover portion.
[10] The sealed compressor according to any one of claims 1 to 9,
wherein the opening of the suction pipe at the sealed container side is positioned between a base end portion of the hood section and a tip end portion of the auxiliary hood hi the suction muffler.
[11] The sealed compressor according to any one of claims 1 to 10,
wherein a cross-section of the hood section in a direction perpendicular to a direction in which the hood section extends is geometrically similar to a cross-section of the auxiliary hood in a direction perpendicular to a direction in which the auxiliary hood extends.
[12] The sealed compressor according to any one of claims 1 to 11,
wherein the suction muffler includes:
a body forming a muffling space;
an inlet pipe having an upstream end forming the opening portion of the suction muffler at the sealed container side and a downstream end which opens in the muffling space;
an outlet pipe having a downstream end communicating with the compression chamber, an upstream end which opens in the muffling space; and a bent portion between the upstream end and the downstream end in the muffling space, a portion of the outlet pipe which is upstream of the bent portion being inclined in a downward direction; and
an oil discharge hole provided in a bottom portion of the muffling space so as to open in a space inside of the sealed container;
wherein the inlet pipe has a shape in which a horizontal length of an opening of the upstream end is smaller than a horizontal length of the opening of the suction pipe, and a vertical length of the opening of the upstream end is greater than a vertical length of the

opening of the suction pipe.
[13] The sealed compressor according to claim 12,
wherein the inlet pipe has a shape in which a vertical length of the inlet pipe is set to 25 to 50% of a vertical length of the muffling space.
[14] The sealed compressor according to claim 12 or claim 13,
wherein the inlet pipe is molded integrally with the body; and
the inlet pipe has a flow passage having a linear shape having no bent portion.
[15] The sealed compressor according to any one of claims 12 tol4,
wherein a cross-section of the inlet pipe in a direction perpendicular to a direction in which the cooling medium gas flows has a substantially rectangular shape.
[16] The sealed compressor according to any one of claims 1 to 15,
wherein the hood section of the suction muffler is formed of wall portions on at least three sides including a lower wall portion at a lower side of the opening portion of the suction muffler at the sealed container side when viewed from the direction in which the hood section extends, the wall portions enclosing the opening portion; and
the lower wall portion is positioned below a lower end of the opening portion the suction pipe at the sealed container side.
[17] The sealed compressor according to any one of claims 12 to 16,
wherein an opposite end of the outlet pipe opens in the same direction as a direction in which an opposite end of the inlet pipe opens.
[18] The sealed compressor according to any one of claims 13 to 17,
wherein the hood section has an inner peripheral surface connected smoothly to the inlet pipe through the opening portion of the suction muffler at the sealed container side.
