Abstract: PROBLEM TO BE SOLVED: To prevent the mixture of a fine foreign matter from an oil supply mechanism of a hermetic compressor by a simple constitution so as to improve the reliability of the compressor.SOLUTION: In such a constitution that a mesh filter 207 is put inside an inlet (caulked type) 208 to prevent the mixture of the foreign matter into a compressor mechanism 102, the mesh filter 207 is nipped in the caulking part provided at the inlet 208 and thereafter it is fixed by laser welding to a lid plate. Thus, a step of brazing the mesh filter 207 can be eliminated. In addition, the attachment of the mesh filter 207 takes place by a nipping method, whereby a stainless steel mesh filter 207 can be also attached, and thus an extremely fine mesh can be constituted.

Abstract: PROBLEM TO BE SOLVED: To provide an electric compressor for sufficiently making both compatible in security of oil separability and miniaturization.SOLUTION: This electric compressor includes a main vessel 1 incorporated with a compression mechanism part 3 and an electric motor 2, an oil feeding device 14 arranged on a sidewall of the main vessel, and a discharge sub-vessel 6 installed via a sealant on the sidewall of the main vessel so as to cover the oil feeding device. The discharge sub-vessel has an oil storage chamber 10 in a lower part, and an oil reserving chamber 23 in a substantially central part for supplying oil to the oil feeding device via an oil suction passage 21 from the oil storage chamber. The electric compressor is constituted so that at least one oil separating jet port 8 is arranged in an upper part of the sidewall of the main vessel, and an oil separating chamber 9 is provided in a position corresponding to the oil separating jet port in an upper part of the discharge sub-vessel. Thus, an external shape of the main vessel is miniaturized, and even if a space in the main vessel is small, refrigerant gas jetting from the oil separating jet port arranged in the discharge sub-vessel, collides with an inner wall of the discharge sub-vessel, oil in the refrigerant gas is efficiently separated, and both the miniaturization and the oil separability can be made compatible.

Abstract: PROBLEM TO BE SOLVED: To reduce cost in an electric compressor, by reducing the number of part items of an oil feeder. SOLUTION: This electric compressor has the oil feeder 19 for storing a motor 5 and a compression mechanism part 4 for compressing and delivering a refrigerant sucked in a compression space connected to the motor 5 via a driving shaft 14 in a main vessel 3, and supplying lubricating oil to the compression mechanism part 4 in a side end part of the motor 5 of the main vessel 3, and is attached with a sub-vessel in the shape of facing a side opening part of the motor 5 of the main vessel 3, and can reduce the cost by reducing the number of part items by integrally forming an oil storage chamber 53 and an oil suction passage 54 in a delivery sub-vessel 80, for introducing the lubricating oil to the oil feeder 19.
