摘要： A piezo-electric fluid pump is provided comprising: a main housing (102); a fluid reservoir located within the main housing; a piston head (114) moveably mounted within the main housing; a piezo-electric stack (106); a bias mechanism arranged to couple the piston head and piezo-electric stack and maintain the piezo-electric stack in compression; an outlet plate (104) statically mounted within the main housing adjacent to the piston head, wherein the adjacent surfaces of the outlet plate and piston head define a pumping chamber (126); an inlet disc valve (130) arranged to permit a one-way flow of fluid from the reservoir into the pumping chamber; and an outlet disc valve arranged to permit a one-way flow of fluid out of the pumping chamber. The combination of pre-loading of the piezo-electric stack in compression and use of inlet disc valve enables the piezo-electric pump described above to exhibit substantial improvement to the pressure and flow capability compared to other piezo-electric pumps.

摘要： The invention provides an attachment assembly for an aircraft joint, and in particular for a strut mounting joint. The attachment assembly comprises a tubular structure having a central axis and at least one open end. The attachment assembly further comprises at least one mounting pin arranged at least partially within the at least one open end of the tubular structure and moveable along the central axis between a retracted position and an extended position. In the extended position, a portion of the at least one mounting pin protrudes from the at least one open end of the tubular structure for engagement with a lug and in the retracted position the at least one mounting pin is withdrawn into the tubular structure for disengagement with the lug. The attachment assembly further comprises a retraction mechanism disposed within the tubular structure and coupled to the at least one mounting pin, the retraction mechanism arranged to convert a rotary input motion into linear motion of the at least one mounting pin along the central axis to drive the at least one mounting pin between the extended position and the retracted position.
