Abstract
A variable geometry compressor housing module has a housing (1) into which a diffuser plate (3), a unison ring (5) and vanes (7) supported by a backplate (9) are inserted. The backplate is fixed to the housing by a crimping process. An actuation mechanism (13) for actuating the vanes (7) is provided on an inlet side of the housing (1). Furthermore, a shroud groove is partly defined by the diffuser plate (3).
Claims37
Variable geometry compressor device, characterized in that a vane cartridge is formed by two wall members (3, 9) attached to each other, which support a set of adjustable vanes (7) and a unison ring (5) for actuating said vanes (7) between each other.
Method for manufacturing a variable geometry compressor device comprising the steps of:
- providing two wall members (3, 9), inserting a unison ring (5) and a set of vanes (7) between said wall members (3, 9) and attaching said wall members to each other to form a vane cartridge.
A variable geometry compressor housing (1) comprising an inlet, a volute, and a shroud groove provided in said inlet, characterized by a diffuser plate (3) a radially inner portion of which at least partly defines said shroud groove.
A method for manufacturing a variable geometry compressor housing module, comprising the steps of:
- providing a die cast compressor housing (1), inserting a diffuser plate (3) a radially outer portion of which at least partly defines a volute in said compressor housing (1), and inserting an assembly consisting of a unison ring (5), a set of vanes (7) and a backplate (9) into said housing such that said unison ring (5) is housed in a groove provided in said diffuser plate (3), characterized in that said shroud groove is at least partly defined by a radially inner portion of said diffuser plate (3), and in that said backplate (9) is attached to said compressor housing (9) by crimping.
A variable geometry compressor housing (1) comprising an inlet, a volute, and a shroud groove provided in said inlet, characterized in that an actuation mechanism (13) is located on an inlet side of said housing (1).
A method for manufacturing a variable geometry compressor housing module, comprising the steps of:
- providing a die cast compressor housing (1), inserting a diffuser plate (3) a radially outer portion of which at least partly defines a volute in said compressor housing (1), and inserting an assembly consisting of a unison ring (5), a set of vanes (7) and a backplate (9) into said housing such that said unison ring (5) is housed in a groove provided in said diffuser plate (3), characterized in that an actuating mechanism is provided on an inlet side of said housing (1), and in that said backplate (9) is attached to said compressor housing (1) by crimping.
