<p>The burster has a body in two parts (10, 12) separable by pistons (20,22,24) in cylinders (14, 16, 18) in the part (12). The pistons have piston rods (32, 34, 36) secured to the part (10) by screws (54). The relative rectilinear movement of the parts (10, 12) is guided by the sliding engagement between the internal cylindrical surfaces (58, 60, 62) of the rings (44) and (46) and of the cylinder (18) and the external surfaces of the piston rods (32, 34,36). Separating movement is effected by fluid fed into the three cylinders via a passage (88) and is limited by engagement between stop surfaces (66, 68) on the part (10) and stop surfaces on the part (12). Approach movement is effected by fluid fed into two cylinders (14, 16) via a passage (90) and is limited by engagement between the inner surface (64) of the part (10) and the rings (44, 46).</p> |
