Abstract: An electric compressor includes a housing; a rotary shaft; an impeller connected to at least a first end portion of the rotary shaft in an axial direction of the rotary shaft, of the first end portion and a second end portion of the rotary shaft in the axial direction; and a pair of air bearings supporting the rotary shaft such that the rotary shaft is rotatable relative to the housing. A load on the first end portion is larger than a load on the second end portion. The pair of air bearings includes a first air bearing, and a second air bearing supporting the rotary shaft at a position closer to the second end portion of the rotary shaft than the first air bearing is. A load carrying capacity of the first air bearing is larger than a load carrying capacity of the second bearing.

Abstract: This intake apparatus for an internal combustion engine having a first bank and a second bank includes: an intake pipe including one new-air intake pipe, two branched pipes, and a junction connecting the new-air intake pipe to the two branched pipes; an EGR gas pipe connected to the junction; and a partitioning member placed around an opening in the EGR gas pipe that opens toward the intake pipe. The partitioning member defines an EGR gas storage chamber. The EGR gas storage chamber has first-bank and second-bank flow passages in which the EGR gas flows toward the first bank and the second bank. The first and second effective cross-sectional areas in the first-bank flow passage and the second-bank flow passage are smaller than the flow passage cross-sectional area in the opening of the EGR gas pipe.
