摘要： A fuel pressure regulator (10) for use with an internal combustion engine includes a housing (12) a valve assembly in the housing, an elastic diaphragm (34) connecting the valve assembly to the housing, a stop (58) on one of the housing (12) or the valve assembly and a spring (22) between the housing (12) and the valve assembly. The housing includes an inlet (14), an outlet (16) and a longitudinal axis. The valve assembly is displaceable along the longitudinal axis by an opening distance when a fuel pressure at least equal an overpressure amount acts on the diaphragm so that the diaphragm does not exceed its yield strength. The diaphragm (34) is in fluid communication with the inlet (14) and elastically displaceable along the longitudinal axis up to a maximum distance. The stop (58) is spaced from the other of the housing (12) or the valve assembly along the longitudinal axis by a travelling distance (D t ) when the valve assembly closes the fluid communication between the inlet and the outlet. The travelling distance is at most equal to the maximum distance and substantially greater than the opening distance.

摘要翻译：一种与内燃机一起使用的燃料压力调节器（10）包括壳体（12），壳体中的阀组件，将阀组件连接到壳体的弹性膜片（34），其中一个壳体（12）或阀组件以及在壳体（12）和阀组件之间的弹簧（22）。壳体包括入口（14），出口（16）和纵向轴线。当至少等于超压量的燃料压力作用在隔膜上时，阀组件可以沿着纵向轴线移动开口距离，使得隔膜不超过其屈服强度。隔膜（34）与入口（14）流体连通，并可沿着纵向轴线弹性移位直到最大距离。当阀组件关闭入口和出口之间的流体连通时，止动件（58）与壳体（12）中的另一个或阀组件沿着纵向轴线间隔行进距离（Dt）。行进距离最大等于最大距离并且大大大于开口距离。
