摘要： An electric valve may include an electric machine having a rotor and a stator, a valve body drivingly connected to the rotor, a valve seat cooperating with the valve body, a housing in which the rotor and the stator are arranged, a split pot arranged in the housing and fluidically separating a dry region from a wet region in the housing, and a spring assembly including at least one spring. The rotor may be arranged in the split pot. The stator may surround the split pot radially on an outside in a circumferential direction. The split pot may protrude beyond an axially outer front side of the rotor. The spring assembly may be coupled to the housing and may rest on the front side spaced apart from the housing such that the spring assembly mechanically impinges on the stator radially and axially.

摘要： A controlling device may include an actuator for mechanically actuating a component. The actuator may be driven by an electric motor. The controlling device provides a return spring. In the case of a failure of the electric motor, the return spring brings about a shifting of the actuator into a starting position. The return spring may be mounted in the controlling device so that it prestresses the actuator into the starting position with a predetermined minimum restoring force.

摘要： 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.

摘要： An expansion valve may include a housing, a threaded bush, a valve body, and a permanent magnet body. The threaded bush may be arranged in the housing and may extend along an axial direction. The threaded bush may include an external thread. The valve body may be partially adjustably received in the threaded bush along the axial direction. The permanent magnet body may be of a pot-shaped design and may be arranged in the housing. The permanent magnet body may extend the threaded bush along the axial direction such that the valve body is partially received in a valve body receptacle surrounded by the permanent magnet body. The permanent magnet body may surround a radially outside of the threaded bush in a common transition portion. In the transition portion, the permanent magnet body may be firmly connected to the threaded bush via a latching connection.

摘要： An actuating device for mechanically actuating a component may include a housing having first and second housing parts lying against one another in a separation plane and fastened to one another, and an electric motor arranged in the first housing part and having an input shaft. The device may also include an output shaft rotatably mounted at least on the second housing part and penetrating a wall thereof, the output shaft one of (i) being connected externally on the second housing part with an actuating element for mechanical coupling with the component which is to be actuated, or (ii) forming an actuating element for mechanical coupling with the component which is to be actuated. The device may further include a gear connecting the input shaft with the output shaft, and having an output gearwheel rotatably connected with the output shaft. The second housing part, in relation to an axis of rotation running perpendicularly to the separation plane, may be able to be fastened to the first housing part in at least two different rotation positions. The output shaft may be arranged eccentrically to the axis of rotation on the second housing part. At least one of the first and second housing parts may have at least one bearing point for rotary bearing at least one additional gearwheel. In a first rotation position between the housing parts, the gear without the additional gearwheel may connect the input shaft with the output shaft with a first transmission ratio. In a second rotation position different from the first rotation position, between the housing parts, the gear with the additional gearwheel may connect the input and output shafts with a second transmission ratio different from the first transmission ratio.
