Abstract
An electric valve, e.g., an electric expansion valve, for expanding a fluid, e.g., for a thermodynamic cycle, is disclosed. The electric valve includes an electric machine including a rotor and a stator interacting with the rotor during operation. A valve body is drive-connected with the rotor. The rotor, the stator, and the valve body are arranged in a valve housing. The valve housing, in an axial direction outside includes a bottom, and a connector projects axially from the bottom. At least one wing projects from the bottom, the at least one wing extending obliquely to the axial direction at least in portions and resiliently supports the bottom on the front side.

An electric valve for expanding a fluid, comprising:
- an electric machine including a rotor and a stator interacting with the rotor during operation,
- a valve body that is drive-connected with the rotor,
- a valve seat interacting with the valve body,
- a valve housing, in which the rotor, the stator, and the valve body are arranged,
- wherein the valve housing, in an axial direction outside includes a bottom, and a connector projects axially from the bottom,
- wherein the valve body is arranged in the connector,
- a valve block, through which a flow path of the fluid leads,
- wherein in the valve block an axial receiving passage is defined, and on an axial front side of the valve block an axially open receiving opening is provided,
- wherein the connector is axially inserted through the receiving opening into the axial receiving passage, and
- wherein at least one wing projects from the bottom, the at least one wing extending obliquely to the axial direction at least in portions and resiliently supports the bottom on the front side.
