Abstract: A valve assembly for controlling the rate of flow of fluid between a valve inlet (18) and a valve outlet (22) comprises a valve housing (10), and a spool valve member (14) that is movable axially within a valve bore (12) provided in the valve housing (10) in an opening direction and a closing direction. The spool valve member (14) is provided with a blind bore (28), the open end of which communicates with the valve outlet, and at least one opening (32, 34; 40; 50, 52, 54, 56) into the blind bore, the at least one opening communicating, to a variable degree dependent on the axial position of the spool valve member (14) within the valve bore (12), with the valve inlet (18). The valve inlet (18) comprises a first boundary (24) and a second boundary (26), wherein the first boundary (24) acts as a control edge so that for axial positions of the spool valve member (14) in which the opening (30, 32; 40; 50, 52, 54, 56) does not overlap the control edge there is no flow into the outlet (22).A blind end (30) of the blind bore (28) is positioned, for all positions of the spool valve member (14) within the valve bore (12), beyond the second boundary (26) in the opening direction of the spool valve member (14).

Abstract translation: 用于控制阀入口（18）和阀出口（22）之间的流体流速的阀组件包括阀壳体（10）和可在阀孔内轴向移动的滑阀构件（14） 12）设置在阀壳体（10）中的打开方向和闭合方向上。 滑阀构件（14）设置有盲孔（28），其开口端与阀出口连通，并且至少一个开口（32,34; 40; 50,52,54,56）进入 盲孔，所述至少一个开口连通到与所述阀入口（18）相关的取决于所述阀孔（12）内的所述滑阀构件（14）的轴向位置的可变程度。 阀入口（18）包括第一边界（24）和第二边界（26），其中第一边界（24）用作控制边缘，使得对于滑阀构件（14）的轴向位置，其中开口 （30,32; 40; 50,52,54,56）不与控制边缘重叠，没有流入出口（22）。盲孔（28）的盲端（30）位于所有 滑阀构件（14）在阀孔（12）内的滑阀构件（14）的打开方向上超过第二边界（26）的位置。
