摘要： A compressor housing (1) includes a scroll member (2), a shroud member (4), and an annular member (6). The scroll member (2) has a first positioning portion (31), which contacts the shroud member (4) to determine the position of the shroud member (4) in relation to the scroll member (2) in the circumferential direction of the impeller (8), and a second positioning portion (32), which contacts the annular member (6) to determine the position of the annular member (6) in relation to the scroll member (2) in the circumferential direction of the impeller (8). The first positioning portion (31) and the second positioning portion (32) are formed at the same position in the circumferential direction of the impeller (8).

摘要： A compressor housing 1 for a turbocharger, which is composed of a scroll piece 20, a shroud piece 30, and an outer-circumferential annular piece 40. The scroll piece 20 includes a through part 22 constituting a discharge port 13, a first intermediate wall surface 23 extended from an intake-side wall surface 21 of a scroll chamber 12 and smoothly connected with the discharge port 13, and a scroll outer-circumferential part 24. The outer-circumferential annular piece 40 includes an outer-circumferential annular press-fit part 44 press fitted into the scroll outer-circumferential part 24, and a protruding part 42 bent from an outer-circumference-side wall surface 41 of the scroll chamber 12. The protruding part 42 is inserted into the through part 22 to form an inner wall surface 14a of an intermediate part 14 that communicates the discharge port 13 with the scroll chamber 12. Then, the compressor housing 1 is fixed to a center housing 2 that is made of iron with high rigidity through joining parts 25 provided at the scroll piece 20.

摘要： A compressor housing is constructed by assembling a scroll piece and a shroud piece. The scroll piece includes an inlet cylindrical portion 21, a front side wall section 22, and an outlet cylindrical portion 23 in which the inner wall surface of the outlet communicating section is curved to connect an inner wall surface of a scroll chamber and that of an outlet port. Fabrication of the scroll piece includes a die casting step that uses a back mold 4 having a first projecting portion 41 and a front mold 5 having a second projecting portion 51 projecting toward the back side to form an intermediate formed body 20 wherein both the first 41 and second projecting portions 51 are disposed within the outlet cylindrical portion 23, and a cutting and removal step that removes residue portions in the intermediate formed body 20 by cutting.

摘要： A turbocharger 1 includes a compressor housing 2 and a bearing housing 3. The compressor housing 2 has a shroud surface 221 and a diffuser surface 222. The bearing housing 3 has an opposite surface 311 facing the diffuser surface 222. An adhesion preventing part 4 is provided on at least one of the diffuser surface 222 and the opposite surface 311. The turbocharger 1 is configured so that compressed air spouts out from the adhesion preventing part 4 to the diffuser passage 15 by an ejector effect caused when compressed air passes through the diffuser passage 15.
