摘要： In a fuel injection valve support structure which can apply a substantially constant set load, the fuel injection valve has first and second load receiving portions, the first load receiving portion being supported on the engine, the second load receiving portion being supported on an elastic support member which receives a set load from a fuel supply cap. The elastic support member includes a base plate placed on the second load receiving portion, and an elastic piece curving rearward from one end toward the other end of the base plate, with an apex portion in pressure contact with the cap, the base plate has a portion overhanging from the second load receiving portion and supporting a tip end portion of the elastic piece. The overhang portion starts bending when a load the overhang portion receives from the cap through the elastic piece reaches or exceeds a predetermined value.
摘要翻译：在能够施加基本恒定的设定负荷的燃料喷射阀支撑结构中，燃料喷射阀具有第一和第二负载接收部分，第一负载接收部分被支撑在发动机上，第二负载接收部分被支撑在弹性支撑件从燃料供给盖接收设定负载的构件。所述弹性支撑构件包括设置在所述第二负载接收部上的基板和从所述基板的一端向另一端向后弯曲的弹性片，其顶端部与所述盖压力接触，所述基板具有该部分从第二负载接收部分伸出并支撑弹性件的末端部分。当悬臂部分通过弹性件从盖子接收的负载达到或超过预定值时，伸出部分开始弯曲。

摘要： In an electromagnetic fuel injection valve which is configured to absorb an unbalanced load applied to sliding portions between a fixed core and a valve stem, thereby enabling a reduction in a frictional resistance of the sliding portions, a guide bush is press fitted in an inner peripheral surface of the fixed core, the valve element includes a valve part configured to cooperate with the valve seat, and the valve stem continuously provided to the valve part and extending toward the guide bush, a sliding member configured to be slidably fitted to an inner peripheral surface of the guide bush is press fitted on the valve stem, wherein an annular gap is provided at least at one of a location between the fixed core and the guide bush and a location between the valve stem and the sliding member, within sliding regions of the guide bush and the sliding member.
摘要翻译：在电磁燃料喷射阀中，其构造为吸收施加到固定芯和阀杆之间的滑动部分的不平衡载荷，从而能够降低滑动部分的摩擦阻力，将导套压配合在内周固定芯的表面，阀元件包括构造成与阀座配合的阀部分，阀杆连续地设置到阀部分并朝向导套延伸;滑动构件，其构造成可滑动地装配到内周边引导衬套的表面压配合在阀杆上，其中环形间隙至少在固定芯和导套之间的位置之一处以及阀杆和滑动构件之间的位置处设置在滑动区域内导套和滑动构件。
