Abstract

An artillery weapon (10) comprising a carriage (100) and an ordnance (200) having a barrel (202) operable to travel between an in-battery position and an out-of-battery position. The artillery weapon (10) further comprises a multifunction cylinder (300) mounted to, and moveable with the ordnance (200). The multifunction cylinder (300) comprises a regulator unit (302) comprising a fluid housing (304) for retaining a working fluid (306), the fluid housing (304) being in fluid communication with a buffer system (308), the buffer system (308) configured to deliver fluid to, and receive fluid from, the fluid housing (304) in response to the barrel (202) moving relative to the carriage (100). The regulator unit fluid housing (304) is in fluid communication with a hydraulic accumulator chamber (310) via a first flow aperture (312). There is also provided an accumulator piston (314) provided in, and operable to move along the accumulator chamber (310). The buffer system (308), regulator unit (302), hydraulic accumulator chamber (310) and first flow aperture (312) are configured such that displacement of the barrel (202) along the barrel axis (204) from an in-battery position to an out-of-battery position causes fluid flow from the buffer system (308) to the fluid housing (304), and thereby causes fluid flow through the first flow aperture (312) into a first accumulator sub-chamber region (316), causing the accumulator piston (314) to move along the accumulator chamber (310) in a first direction and thereby cause gas in a second accumulator sub-chamber region (318) to compress.
