Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 72 words
A compressor with a plastic casing (1, 1', 1 "), wherein the plastic casing (1, 1', 1") comprises at least one thermosetting plastic body (11, 11', 11 ") for providing an intake port (3, 3', 3"), a compressor duct (7, 7', 7") and an outlet port (5, 5', 5"), characterized in that a thermoplastic (13, 13', 13") at least partially covers the thermosetting plastic body (11, 11', 11 ") like a hood.
Claim 2
Dependent Claim 24 words
A compressor according to claim 1, characterized in that the compressor is designed as a radial flow compressor, preferably for use in a turbocharger.
Claim 3
Dependent Claim 46 words
A compressor according to claim 1 or 2, characterized in that the thermoplastic (13, 13', 13") covers the full surface of the thermosetting plastic body (11, 11', 11") at least in the region of the intake port (3, 3") and/or of the compressor duct (7, 7').
Claim 4
Dependent Claim 49 words
A compressor according to any one of the preceding claims, characterized in that the thermosetting plastic body (11, 11', 11") has a stepped end (111, 111', 111") for receiving a compressor-casing back panel (9, 9', 9"), which compressor-casing back panel (9, 9', 9") is preferably formed of a metal.
Claim 5
Dependent Claim 33 words
A compressor according to claim 4, characterized in that for providing a sealing lip, the thermoplastic (13) extends with an extension (133) beyond the stepped end (111) of the thermosetting plastic body (11).
Claim 6
Dependent Claim 38 words
A compressor according to claim 5, characterized in that the compressor-casing back panel (9) can be locked into place between the stepped end (111) of the thermosetting plastic body (11) and the extension (133) of the thermoplastic (13).
Claim 7
Dependent Claim 45 words
A compressor according to any one of the preceding claims, characterized in that the thermosetting plastic body (11, 11', 11") tapers in the region of the intake port (3, 3', 3 ") towards the free end (115, 115', 115"), particularly because of inside-wall material saving.
Claim 8
Dependent Claim 35 words
A compressor according to claim 7, characterized in that the thermosetting plastic end (115, 115') extends beyond the thermoplastic (13, 13'), or the thermoplastic (13") encompasses the thermosetting plastic end (115") with an extension (136").
Claim 9
Dependent Claim 25 words
A compressor according to any one of the preceding claims, characterized by at least one fastening means (117", 118") in the thermosetting plastic body (11").
Claim 10
Dependent Claim 49 words
A compressor according to claim 9, characterized in that the fastening means (117", 118") is covered by the thermoplastic (13") when it opens towards the compressor-casing back panel (9"), and/or is free from the thermoplastic (13") when it opens in a direction away from the compressor-casing back panel (9").
Claim 11
Independent Claim 46 words
A method for manufacturing a plastic casing of a compressor according to any one of the preceding claims, characterized in that the thermosetting plastic body is formed as a basic body and the basic body is subsequently covered on its outside with thermoplastic at least partially.
Claim 12
Dependent Claim 27 words
A method according to claim 11, characterized in that the basic body is manufactured as one piece, preferably in an injection process, particularly in an injection-moulding process.
Claim 13
Dependent Claim 28 words
A method according to claim 11 or 12, characterized in that the thermoplastic is injection-moulded on the basic body, particularly in an injection-moulding process, or is clipped thereon.
Claim 14
Independent Claim 23 words
A method according to any one of claims 11 to 13, characterized in that a highly tough thermoplastic is selected as the thermoplastic.
Claim 15
Independent Claim 23 words
A method according to any one of claims 11 to 14, characterized in that a two-component plastic casing for a turbocharger is manufactured.
