Abstract: The present disclosure relates to a servovalve assembly comprising a pair of opposed nozzles spaced apart by a first gap. A control element positioned in the first gap (G) between the pair of opposed nozzles. Each nozzle has an outlet opening. The control element has a central control portion and two resiliently deformable end portions at opposite ends of the central control portion. The central control portion is perpendicular to a central axis (C) of each nozzle outlet opening.

Abstract: The present disclosure relates to a nozzle assembly for use in a servo valve. The nozzle assembly comprises three nozzle parts and a housing. The second part is coaxial with the first part and surrounds at least a first portion of the first part. The third part is coaxial with the first part, and a first portion of the third nozzle part surrounds a first portion of the second nozzle part, and a second portion of the third part is attached to a second portion of the first part. First and second nozzle parts are made of materials having approximately the same first coefficient of thermal expansion (TE1), and third part and housing are made of materials having approximately the same second coefficient of thermal expansion (TE2). TE1 is different from TE2. The interaction between the portions due to the differences in TE1 and TE2 allow the nozzle assembly to compensate for temperature fluctuations during and operation whilst remaining firmly held in position.

Abstract: A method of manufacturing a hydraulic plug includes providing a shell comprising a circumferential wall, a sealed end, an open end and a cylindrical cavity opening to the open end is provided. The open end of the shell is wider externally than the sealed end. A head of an expander is inserted into the cavity. The head of the expander has a convex contact surface which is rounded in an axial direction (A) of the cavity. A region of the shell adjacent its open end is plastically deformed causing material from the circumferential wall of the shell to be displaced radially inward around the head of the expander to form a constricted opening retaining the expander within the cavity. The deforming reshapes an internal surface of the cavity from a cylindrical to a non-linear shaped ramp leading up to a constricted opening.
