摘要： The strip (16) is of the type comprising a wall portion (20) for delimiting a cell (18) for receiving a fuel rod (4) and allowing flow of a coolant upwardly through the spacer grid (14), a spring (22) provided on the wall portion (20) for biasing a fuel rod (4) extending through the cell (18) away from the wall portion (20), the spring (22) being cut out in the strip (16) and delimited by a slot (40) and a motion limiter (34) formed in the strip (16) on the wall portion (20) to limit motion of a fuel rod (4) received in the cell (18) towards the wall portion (20) against action of the spring (22).
According to one aspect of the invention, the motion limiter (34) is located on an edge (54) of the slot (40) opposite the spring (22) and defines a risen portion (56) on said edge (54).
摘要翻译：条带（16）的类型包括壁部分（20），用于限定用于容纳燃料棒（4）并且允许冷却剂向上流过间隔栅格（14）的电池（18），弹簧（22））设置在所述壁部分（20）上，用于将延伸穿过所述电池（18）的燃料棒（4）偏离所述壁部分（20），所述弹簧（22）在所述带材（16）中切割并且由形成在壁部分（20）上的带（16）中的狭槽（40）和运动限制器（34），以限制容纳在电池（18）中的燃料棒（4）朝向壁部分（20）的运动，反对春天的动作（22）。根据本发明的一个方面，运动限制器（34）位于与弹簧（22）相对的槽（40）的边缘（54）上并且限定了所述边缘（54）上的上升部分（56）。

摘要： The lower nozzle (12) is of the type having an axis (A-A) and comprising a transverse lower tie plate (16) for channelling the coolant through the lower tie plate (16) and a tubular skirt (18) extending axially from the periphery of the lower tie plate (16), the skirt (18) delimiting an axial housing (24) closed at one end by the lower tie plate (16) and open at the opposite end, a debris filter (20) configured for axial insertion in the housing (24) and snap-fit springs (38) for retaining the debris filter (20) in the housing (24) after insertion. The springs (38) are configured to shift the debris filter (20) axially towards the lower tie plate (16).
摘要翻译：下喷嘴（12）是具有轴线（AA）的类型，并且包括用于将冷却剂引导通过下连接板（16）的横向下拉板（16）和从周边轴向延伸的管状裙部（18）所述裙部（18）限定一个轴向壳体（24），所述轴向壳体（24）在一端由所述下部连接板（16）封闭并且在相对端处敞开;碎屑过滤器（20）被构造成用于轴向插入在壳体（24）和用于在插入之后将碎屑过滤器（20）保持在壳体（24）中的卡合弹簧（38）。弹簧（38）构造成使碎屑过滤器（20）沿轴向朝向下连接板（16）移动。
