Abstract
An electric refrigerant drive, in particular a refrigerant compressor for an air conditioner of a motor vehicle, has an electric motor drive module and a compressor module coupled to the drive module. The drive module has a motor housing which houses an electric motor with a rotatable motor shaft and is joined to an end shield. The drive module also comprises a fluid-tight housing partition opposite the end shield, thereby forming an electronic housing that receives an electronic motor unit and is closed by a housing cover. The compressor module has a compressor housing which is attached to the end shield of the motor housing of the drive module and which receives a compressor part that is coupled or can be coupled to the drive module so as to be driven.
Claims13
An electric refrigerant drive, comprising:
- an electric motor drive module and a compressor module coupled to said drive module;
- said drive module having a motor housing, said motor housing accommodating an electric motor with a rotatable motor shaft and being joined to an end shield, and a fluid-tight housing partition wall disposed opposite said end shield to form an electronics housing, said electronics housing accommodating motor electronics and being closed with a housing cover;
- said compressor module having a compressor housing that is connected to said end shield of said motor housing of said drive module, said compressor housing accommodating a compressor part propulsively coupled, or configured to be propulsively coupled, with said drive module;
- said compressor housing having a central plate on a drive-side housing end face of the compressor module;
- and
- said drive module and said compressor module being disposed to form a counter-pressure chamber for receiving a pressurized refrigerant between said end shield of said drive module and said central plate of said compressor module.
