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: 一种用于控制阀入口（18）和阀出口（22）之间的流体流动速率的阀组件包括阀壳体（10）和滑阀构件（14），滑阀构件可在阀孔 设置在所述阀壳体（10）中的打开方向和关闭方向上。 所述滑阀构件（14）设置有盲孔（28），所述盲孔（28）的开口端与所述阀出口连通，并且至少一个开口（32,34; 40; 50,52,54,56） 所述至少一个开口根据阀孔（12）内的滑阀构件（14）的轴向位置与阀入口（18）连通至可变程度。 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）不与控制边缘重叠时，没有流入出口（22）。 对于滑阀构件（14）在阀孔（12）内的所有位置而言，盲孔（28）的盲端（30）定位成在滑阀的打开方向上超过第二边界（26） 成员（14）。
