Motor-driven compressor

摘要

A motor-driven compressor that suppresses the transmission of vibration and noise to the exterior, while obtaining heating performance that is sufficient for use in a heat pump. The motor-driven compressor includes a compressor mechanism, which compresses a refrigerant, and a motor mechanism, which actuates the compressor mechanism. The motor-driven compressor further includes an inner housing, which accommodates the compressor mechanism and the motor mechanism in a sealed state, and an outer housing, which accommodates the inner housing. The outer housing includes a mounting portion that can be mounted to another member. A first intermediate member is arranged between the inner housing and the outer housing. The first intermediate member includes anti-vibration and thermal insulation properties.

1. A motor-driven compressor comprising:
a compressor mechanism that compresses a refrigerant; a motor mechanism that actuates the compressor mechanism; an inner housing that accommodates the compressor mechanism and the motor mechanism in a sealed state; an outer housing that accommodates the inner housing, wherein the outer housing includes a mounting portion that can be mounted to another member, and the outer housing includes two opposing open ends in the longitudinal direction of the outer housing; and a first intermediate assembly arranged between the inner housing and the outer housing at longitudinal ends of the inner housing thereby sealing an interior space between the outer housing and the inner housing, wherein the first intermediate assembly includes an anti-vibration material having an anti-vibration property and thermal insulation material having a thermal insulation property, and the thermal insulation material is sandwiched in the longitudinal direction by the anti-vibration material, the anti-vibration material protrudes beyond the thermal insulation material in the longitudinal direction, wherein the inner housing protrudes beyond the first intermediate assembly in the longitudinal direction of the inner housing.
