Abstract

A device for actuating a valve, comprising a casing, said casing exhibiting a transparent region and said casing preferentially having been formed from an upper part and a lower part, a transmission assembly, an electric motor and a base board for attaching electrical components, wherein LEDs or a multicolour LED and an optical waveguide have been arranged in the casing, preferentially on the base board, the position or another function of the valve being indicated by the LEDs lighting up, and the optical waveguide collimating and focusing the light of the LEDs for the purpose of indicating the position or malfunction.

First claim

1 . A device for actuating a valve, comprising: a casing, said casing exhibiting a transparent region and said casing preferentially having been formed from an upper part and a lower part, a transmission assembly, an electric motor and a base board for attaching electrical components, wherein LEDs or a multicolour LED and an optical waveguide have been arranged in the casing, preferentially on the base board, the position or another function of the valve being indicated by the LEDs lighting up, and the optical waveguide collimating and focusing the light of the LEDs for the purpose of indicating the position or malfunction.

2 . The device for actuating a valve, according to claim 1 , wherein the transmission assembly exhibits an upper base plate and a lower base plate, gearwheels for transmitting the power of the electric motor to the valve to be driven having been arranged between the upper base plate and the lower base plate.

3 . The device for actuating a valve, according to claim 1 , wherein the upper base plate and the lower base plate have been spaced from one another by spacer bolts.

4 . The device for actuating a valve, according to claim 1 , wherein the base board rests on a carrier plate, said carrier plate having been arranged on the upper base plate of the transmission assembly.

5 . The device for actuating a valve, according to claim 1 , wherein a position indicator has been arranged in the casing.

6 . The device for actuating a valve, according to claim 1 , wherein the transparent region in the casing takes the form of inspection glass, said inspection glass serving for discerning the position indicator.

7 . The device for actuating a valve, according to claim 1 , wherein the optical waveguide has been arranged in the background of the position indicator.

8 . The device for actuating a valve, according to claim 1 , wherein the LEDs have been arranged on the base board.

9 . The device for actuating a valve, according to claim 1 , wherein the optical waveguide has been formed from Plexiglas or transparent polycarbonate.

10 . The device for actuating a valve, according to claim 1 , wherein the optical waveguide takes the form of an injection moulding.

11 . The device for actuating a valve, according to claim 1 , wherein the electric motor has been arranged on the upper base plate of the transmission assembly.

12 . The device for actuating a valve, according to claim 1 , wherein the optical waveguide exhibits a straight region and a circular region.

13 . The device for actuating a valve, according to claim 1 , wherein the optical waveguide exhibits an inner ring and an outer ring in the circular region.

14 . The device for actuating a valve, according to claim 1 , wherein grooves have been arranged in the circular region, preferentially on the outer ring, said grooves preferentially forming a structure.
