The jacket is formed preferably of three or more sections—the trunnion section, an inter-mediate section or t^ections. and the valve section—bolted together. The trunnion and inter-mediate sections are sujiported from the barrel by radial webs or studs, leaving ample spacefor the free passage of tlie fluid from the trunnions to the breech.
