ABSTRACT 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. DOC. NO. PAT2002
