An electric compressor includes a compression member configured to compress fluid, an electric motor configured to drive the compression member, an inverter configured to drive the electric motor, a housing accommodating the compression member, the electric motor, and the inverter, and a soundproof cover covering the housing. The housing includes a plurality of housing elements. The soundproof cover has a facing portion facing the housing. The facing portion has a groove that surrounds a boundary between two of the housing elements that are adjacent to each other and is distant from the boundary.

Electric compressor

A vehicle electric fluid machine includes: a housing provided with a mounting leg having an insertion hole; a fastener having a shaft portion inserted into the insertion hole and a head portion at one end of the shaft portion, the fastener fastening the other end of the shaft portion to a mounting object; a sleeve disposed between the mounting leg and the shaft portion, elastic vibration dampers disposed on opposite sides of the mounting leg in its axial direction, each of the elastic vibration dampers having a cylindrical portion disposed between an inner circumferential surface of the mounting leg and an outer circumferential surface of the sleeve, and a collar extending from one of opposite ends of the cylindrical portion in a radial outward direction of the cylindrical portion; and an annular plate through which the fastening force is applied to the mounting leg through the collar.

Vehicle electric fluid machine

A motor-driven compressor, a housing structure for a motor-driven compressor, and a method of installing a soundproof cover on a motor-driven compressor are provided. A soundproof cover includes layers that include a first layer and a second layer. The first layer is placed over a housing, and the second layer is placed over the first layer. Each of the layers includes a first segment and a second segment. A second selection layer is located inward of a first selection layer. A boundary in the second selection layer is located above the boundary of the first selection layer.

A vehicle electric fluid machine includes: a housing provided with a mounting leg; a fastener having a shaft portion and a head portion at one end of the shaft portion, the fastener fastening the other end of the shaft portion to a mounting object; a sleeve disposed between the mounting leg and the shaft portion; elastic vibration dampers each having a cylindrical portion and a collar extending from one of opposite ends of the cylindrical portion in its radial outward direction; and an annular plate through which a fastening force is applied to the mounting leg. The annular plate has an elongated protrusion protruding toward the mounting leg, the elongated protrusion spaced from the collar with a predetermined clearance formed radially outside the collar. A deformation limit of the collar is defined by the elongated protrusion being in contact with the collar.
