Abstract
An electric stator for an expansion valve may include a first and a second coil body, a first electric connecting element, and a second electric connecting element. The first and second coil bodies may be substantially ring-shaped and extend along a circumferential direction. The first electric connecting element may protrude from the first coil body along an axial direction. The second electric connecting element may protrude from the second coil body. The first and second coil bodies may be arranged next to one another along the axial direction and may be fastened to one another via a common positioning aid.

An electric stator for an expansion valve, comprising:
- a first coil body and a second coil body which are substantially ring-shaped and extend along a circumferential direction, each of the first and second coil body including a stator winding arranged thereon which can be electrically supplied with current;
- a first electric connecting element protrudes from the first coil body along an axial direction which runs perpendicular to the circumferential direction;
- a second electric connecting element protrudes from the second coil body;
- wherein the first and second coil bodies are arranged next to one another along the axial direction and are fastened to one another via a common positioning aid;
- and
- wherein the first and second connecting elements are arranged next to one another along the circumferential direction and are connected to one another in a positive manner.
An expansion valve for an air conditioning system of a motor vehicle, comprising:
- a housing surrounding a housing interior;
- a rotor which can be rotated relative to the housing;
- and
- a stator arranged in the housing interior, the stator including:
- a first coil body and a second coil body which are substantially ring-shaped and extend along a circumferential direction, each of the first and second coil body including a stator winding arranged thereon which can be electrically supplied with current;
- a first electric connecting element protrudes from the first coil body along an axial direction which runs perpendicular to the circumferential direction;
- a second electric connecting element protrudes from the second coil body;
- wherein the first and second coil bodies are arranged next to one another along the axial direction and are fastened to one another via a common positioning aid;
- and
- wherein at least one guide rail is present at the housing for guiding the first and/or second connecting element or a first and/or second connecting housing along the axial direction.
An electric stator for an expansion valve, comprising:
- a first coil body and a second coil body that are substantially ring-shaped and extend along a circumferential direction, each of the first coil body and the second coil body including a stator winding arranged thereon that can be electrically supplied with current;
- a first electric connecting element protruding from the first coil body along an axial direction that runs transversely to the circumferential direction;
- a second electric connecting element protruding from the second coil body;
- wherein the first coil body and the second coil body are arranged next to one another along the axial direction and are secured to one another via a common positioning aid;
- wherein the first connecting element and the second connecting element have a respective electrically insulating first or second connecting housing, in which two electrically conductive connections are connected in an electrically conductive manner to the stator winding of the first and second coil bodies;
- and
- wherein at least one guide fin extends axially and engages with a recess, the recess is formed in a complementary manner to the at least one guide fin and extends axially and is provided at the second connecting housing and protrudes from the first connecting housing, or is provided at the first connecting housing and protrudes from the second connecting housing.
