A flow limiter valve assembly comprising a housing defined by an end cap and a guide base, a fluid inlet orifice provided in the base and a fluid outlet orifice in the circumferential wall of the housing, with a fluid flow path defined from the inlet orifice to the outlet orifice. The valve assembly further comprises a spool mounted in the base of the housing and arranged to be axially moveable relative to the housing end cap and biasing elements to bias the spool away from the end cap. When the spool is biased away from the end cap, the fluid flow path is defined by a gap between the end cap and the spool such that fluid can flow from the inlet orifice through this gap to the outlet orifice.
