Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Hereinafter, the disclosure is explained in more detail based on exemplary embodiments. Technical features having the 2019063 EP ENG same function are identified in the Figures with identical reference numerals. It shows:

[0056] FIGS. 1a and 1b the inventive regulating valve 1 for a door drive 2, and

[0057] FIG. 2 the inventive door drive 2.

DETAILED DESCRIPTION OF THE DRAWINGS

[0058] FIG. 1a shows the inventive regulating valve 1 for a door drive 2, wherein the regulating valve 1 has an axis of rotation 3, wherein the regulating valve 1 includes at least two ends 8, wherein the regulating valve 1 includes at least two sealing sections 12, wherein the regulating valve 1 includes a regulating section 4, wherein the regulating section 4 is disposed between the sealing sections 12.

[0059] Three respective radial thickenings 5 form both sealing sections 12. The radial thickenings 5 are spaced apart from each other along the axis of rotation 3. A radial tapering 6 forms the regulating section 4. The radial thickenings 5 are integrally formed with the regulating valve 1. The radial thickenings 5 extend rotation-symmetrically about the axis of rotation 3. The tapering 6 likewise extends rotation-symmetrically about the axis of rotation 3. In the direction of the axis of rotation 3, the tapering 6 has a symmetric cross-section.

[0060] The regulating valve 1 has two engagements 7. The regulating valve 1 has two ends 8. One engagement 7 is disposed at each end 8. Thus, each end 8 has an engagement 7. In FIG. 1b, the regulating valve 1 of FIG. 1a is illustrated in a perspective view, so that the engagements 7 are better visible. Respectively one hexagon socket forms the engagements 7.

[0061] The regulating valve 1 includes a thread 9. The thread 9 is disposed at the right of the two ends 8 of the regulating valve 1. Thus, the right one of the two ends 8 includes both an engagement 7 and a thread 9. The thread 9 is formed coaxially to the axis of rotation 3.

[0062] The regulating valve 1 includes a guide section 10. The guide section 10 is disposed at the left one of the two ends 8. The guide section 10 has a smaller diameter than the right one of the two ends 8.

[0063] The regulating valve 1 includes two surrounding annular sealing grooves 11. The annular sealing grooves 11 serve for accommodating non-illustrated sealing rings. The annular sealing grooves 11 are disposed between one of the ends 8 and the nearest sealing section 12.

[0064] The thread 9 allows for screwing the regulating valve 1 into the regulating valve reception 14 of a door drive 2 (see FIG. 2). For this purpose, the regulating valve reception 14 has a receiving thread. The regulating valve 1 is rotatable about the axis of rotation 3 thereof via the engagement 7. When rotating the regulating valve 1 in the regulating valve reception 14, the regulating valve 1 is displaced along the axis of rotation 3 thereof. Hereby, the regulating valve 1 is also displaced in relation to hydraulic channels disposed in the door drive 1. Depending on the position of the regulating valve 1 in the door drive 2, hydraulic fluid can flow along the tapering 6 of the regulating valve 1 or is blocked.

[0065] FIG. 2 shows the inventive door drive 2. The door drive 2 includes a regulating valve reception 14. An inventive regulating valve 1 is disposed in the regulating valve reception 14. One end 8 of the regulating valve 1 is visible in FIG. 2. The end 8 of the regulating valve 1 includes an engagement 7. A hexagon socket forms the engagement 7.

[0066] The door drive 2 has a longitudinal axis 13. The door drive 2 includes an output shaft 18. The output shaft 18 is supported in the door drive 2. The output shaft 18 extends vertically to the longitudinal axis 13. The output shaft 18 is rotatable about an output axis 19. The output axis 19 extends vertically to the longitudinal axis 13. The output shaft 18 protrudes from the top side and from the bottom side of the door drive 1 from the door drive 1. At the two ends thereof, the output shaft 18 has a connection 20. In the Figure just the upper connection 20 is visible. The connections 20 serve for connecting a non-illustrated arm assembly. The regulating valve 1 is disposed vertically to the output axis 19.
