    Abstract: A dosing device (1) is provided that is suitable for administering a reagent (2) into an exhaust chamber (4) of an internal combustion engine. The device (1) comprises a nozzle body (6) and an insulating jacket (5) wherein the jacket (5) is mounted to the nozzle body (6) at one or more mounting points (8,9), and wherein the dosing device (1) is adapted to engage with a port (10) located in the wall of an exhaust chamber (4). The insulating jacket (5) defines a compartment (11), which can comprise an insulating material or can be substantially evacuated. The dosing device (1) of the invention is advantageously insulated from the elevated temperatures in the surrounding environment, thereby allowing for the reagent to be maintained at an optimal working temperature range.

    Abstract: Apparatus is disclosed that is suitable for connecting first and second electrical connection points arranged at different angular orientations, for example in a fuel injector having a pressure sensor integrated into a cap nut. The apparatus comprises a generally cylindrical first body (118) having a first electrical connection point (B), a generally tubular second body (122) attachable to an end region (120) of the first body (118) and having a second electrical connection point (136), a first annular conductor (152) associated with the first body (118) and connected to the first connection point (B), and a second annular conductor (164) associated with the second body (122) and connected to the second connection point (136). The first and second connection points (B, 136) are located laterally from a common axis (A) of the first and second bodies (118, 122) and, when the second body (122) is attached to the first body (118), the first and second annular conductors (152, 164) are in electrical contact so as to connect the first connection point to the second connection point (136) irrespective of whether the first and second connection points are in alignment in a direction parallel to the common axis (A).

    Abstract: The invention concerns an encapsulated actuator as well as a method of encapsulating an actuator/stack in an encapsulation member, which comprising at least an innermost heat shrinkable, polymeric sleeve member and an overlaying outermost, heat shrinkable, polymeric sleeve member. The sleeve members have each a different shrinkage temperature, wherein the shrinkage temperature of the outermost sleeve member is higher than the shrinkage temperature of the innermost sleeve member. The method comprising essentially the following steps:
    a. Arranging the stack inside the innermost sleeve member,
    b. Arranging the outermost sleeve member so as to overlay the innermost sleeve member(s),
    c. Placing the stack under vacuum so as to degas it,
    d. Heating the stack above the shrinkage temperature of the outermost sleeve member so as to shrink the outermost sleeve member,
    e. Placing the stack under atmospheric pressure
    f. Cooling the stack.
