Abstract

There is provided a linear actuator (10) comprising: an output rod (20) having a longitudinal axis (22) and a distal end (11); a structure (26) comprising a friction surface (28) radially spaced from the output rod (20), wherein the output rod (20) is configured for extension and retraction in an axial direction relative to the structure (26); an input rod (18) for driving movement of the output rod (20), wherein the input rod (18) is axially moveable relative to the output rod (20); and a locking element (30; 48). The locking element (30; 48) comprises: a brake portion (32; 50) arranged between the friction surface (28) and the output rod (20); and an inclined surface (26; 54). The locking element (30; 48) is axially moveable relative to the output rod (20), wherein when the input rod (18) is moved in a first axial direction (D1; D2) relative to the structure (26), the input rod (18) contacts the locking element (30; 48) so as to drive the output rod (20) in the first axial direction (D1; D2), and wherein when an external load acts on the distal end (11) of the output rod (20) in the first axial direction (D1; D2), an engagement feature (40; 58) of the output rod (20) is pushed against the inclined surface (26; 54) of the locking element (30; 48) so as to wedge the brake portion (32; 50) of the locking element (30; 48) against the friction surface (26), limiting movement of the output rod (20) in the first axial direction (D1; D2).
