Abstract

The disclosed subject matter relates to a hydraulic and electrical interface ring for a turbine engine, characterized in that said ring comprises fluid transfer pipes which axially pass therethrough and having axial ends that form axial interlocking means, the supporting means of at least one electrical device, and at least one electrical linking connector of the device, said connector being configured to engage by axial interlocking with a complementary electrical connector of another part.

First claim

The invention claimed is:

1. Hydraulic and electrical interface ring for a turbine engine, comprising:
ducts configured to transfer fluid passing axially through the ring, the axial ends of which form axial interlocking means;
an electrical equipment support; and
at least one connector configured to electrically connect an electrical equipment supported by the electrical equipment support, said connector being configured to interact by axial interlocking with a complementary electrical connector of another part.

2. The ring according to claim 1 , further comprising means for fastening to said other part.

3. The ring according to claim 1 , wherein the electrical equipment includes at least one axial position sensor.

4. The ring according to claim 3 , wherein the electrical equipment support is articulated to one end of the sensor by a ball-joint connection.

5. The ring according to claim 1 , wherein at least one of the ends of each duct is tubular and projects axially on the ring.

6. An assembly, comprising:
a hydraulic and electrical interface ring including
ducts configured to transfer fluid passing axially through the ring, the axial ends of which form axial interlocking means;
elements for supporting at least one electrical equipment; and
at least one connector configured to electrically connect the equipment, said connector being configured to interact by axial interlocking with a complementary electrical connector of another part; and

an annular collar including a cylindrical bearing surface for centering the ring and an annular face for axially supporting the ring, an electrical connector configured to interact by axial interlocking with the at least one connector of the ring when the ring is axially supported on the collar, and longitudinal channels configured to circulate fluid, which each have a longitudinal end which is opposite an end of a duct of the ring and adapted to be connected to said end by a fluid connection.

7. The assembly according to claim 6 , wherein the collar comprises holes in which nuts or inserts are accommodated, the ring comprising axial holes for the passage of screws which are adapted to be screwed into said nuts or inserts.

8. The assembly according to claim 6 , wherein a cavity configured to receive fluid is provided between the collar and the ring, said cavity being connected to the longitudinal ends of the channels in the collar and to the ends of the ducts of the ring.

9. The assembly according to claim 8 , wherein the cavity comprises a circular groove which is provided in the collar and a circular groove which is provided in the ring.

10. The assembly according to claim 6 , wherein the longitudinal channels comprise pipes which are attached to the collar or are formed in bosses on the collar.

11. Turbine engine module, comprising an assembly according to claim 6 , which is mounted on an axial end of a linear actuator, said linear actuator comprising a fixed inner part and an outer part which can move in translation on the fixed inner part, the movable outer part defining chambers around the fixed inner part, at least one of said chambers being supplied with fluid by rods of which the axial ends opposite the linear actuator are configured to be interlocked in the ducts of the ring.

12. The module according to claim 11 , wherein the movable part of the actuator is fastened to an end of at least one axial position sensor, the opposite end of which is fastened to the ring.

13. Method for mounting a turbine engine module having an assembly according to claim 6 , said method comprising:
providing a linear actuator comprising a fixed inner part and an outer part which can move in translation on the fixed inner part, the movable outer part defining chambers around the fixed inner part, at least one of said chambers being supplied with fluid by rods of which the axial ends opposite the linear actuator are configured to be interlocked in the ducts of the ring;
mounting the ring of the assembly at an axial end of the actuator in such a way that the axial ends of the rods which are opposite the actuator are interlocked in the ducts of the ring;
moving the actuator and the ring in axial translation towards the collar, until the ring is axially supported on the collar, the ducts of the ring are in fluid communication with the channels in the collar, and the connector of the ring is interlocked with the electrical connector of the collar; and
fastening the ring to the collar.

14. The ring according to claim 1 , further comprising at least one hole for receiving a fastener for fastening the ring to said other part.
