  • Patent number: 11692459
    Abstract: A method for manufacturing a turbine engine part in which a first rough casting element includes a first face and a second face opposite to each other is assembled by the second face on an orifice which has a second element of the part. The method includes machining a through-cavity in the first element which opens at the first face and from the second face of the first element and machining the first face of the first element so as to form an area suitable for ensuring the attachment of a conduit on the first element. The machining of the cavity and of the first face is achieved by using a machining reference frame based on the second element.

  • Publication number: 20150316425
    Abstract: A pump including a first substrate in a plane with a side having a cavity formed therein. There are intake and discharge channels in the side for admitting and discharging a fluid. There is a second substrate having a side joined to the first substrate, to close the channels and form tubes in which pumped fluid flows. The second substrate also has a membrane to close the cavity to form a leak-tight chamber. The membrane is deformable: in order to expel the fluid out of the chamber via the discharge channel, and to suck the fluid into the chamber via the intake channel. There is actuator capable of converting the energy into movement of the membrane and an assembly for measuring the temperature/flow rate of the fluid. There is a temperature probe placed on the exterior side of the insulating material to insulate thermally the probe from the substrate.
