## Abstract

A drive device for an injection valve may include an actuator configured for exerting a force along a first force action axis, a lever device coupled to the actuator, an output element coupled to the lever device and configured for absorbing a force from the lever device along a second force action axis, wherein the first and second force action axes are arranged offset with respect to one another, and a transmission element arranged between the actuator and the lever device. The transmission element may be coupled to the actuator in a first contact region and to the lever device in a second contact region. The first contact region of the transmission element may be arranged such that it is penetrated by the first force action axis. The second contact region of the transmission element may be arranged such that it is penetrated by the second force action axis.

## Claims

### Claim 1

A drive device for an injection valve, comprising:
an actuator configured to exert a force along a first axis of force action,
a lever device mechanically coupled to the actuator,
a drive output element mechanically coupled to the lever device and configured to absorb a force from the lever device along a second axis of force action, wherein the second axis of force action is offset with respect to the first axis of force action, and
a transmission element arranged between the actuator and the lever device, the transmission element being coupled in a first contact region to the actuator and coupled in a second contact region to the lever device,
wherein the first contact region of the transmission element is intersected by the first axis of force action, and
wherein the second contact region of the transmission element is intersected by the second axis of force action.

### Claim 2 (depends on 1)

The drive device of claim 1, wherein the transmission element comprises a convexly curved shape in at least one of the first and second contact regions.

### Claim 3 (depends on 1)

The drive device of claim 1, wherein the transmission element comprises a substantially hemispherical shape in at least one of the first and second contact regions.

### Claim 4 (depends on 1)

The drive device of claim 1, wherein at least one of the first and second contact regions of the transmission element comprises a substantially hemispherical shape with a radius substantially smaller than half of a distance between the first contact region and the second contact region.

### Claim 5 (depends on 1)

The drive device of claim 1, wherein at least one of the first and second contact regions of the transmission element comprises a substantially spherical segment having a radius greater than half of a distance between the first contact region and the second contact region.

### Claim 6 (depends on 1)

The drive device of claim 1, wherein the transmission element comprises a pin.

### Claim 7

An injection valve comprising:
a drive device comprising:
an actuator configured to exert a force along a first axis of force action,
a lever device mechanically coupled to the actuator,
a drive output element mechanically coupled to the lever device and configured to absorb a force from the lever device along a second axis of force action, wherein the second axis of force action is offset with respect to the first axis of force action, and
a transmission element arranged between the actuator and the lever device, the transmission element being coupled in a first contact region to the actuator and coupled in a second contact region to the lever device,
wherein the first contact region of the transmission element is intersected by the first axis of force action, and
wherein the second contact region of the transmission element is intersected by the second axis of force action.
