    • A fluid flow control valve (10) having an elongated valve body (14) with a longitudinally extending aperture (14a) and a plurality of longitudinally spaced, radially extending ports (14b) formed therein. The valve body (14) includes an undercut portion (14c) located between two adjacent radially extending ports (14b). A valve spool (12) within the longitudinally extending aperture (14a) of the valve body (14) can be moved between first and second end limits of travel. The valve spool (12) has a plurality of lands (12a) and reduced diameter portions (12b) defining fluid passages (18) for fluid communication with selective radially extending ports (14b) of the valve body (14) depending on a longitudinal position of the valve spool (12) within the valve body (14). A longitudinally extending passage (12c) and a radially extending passage (12d) are formed in the valve spool (12). The radially extending passage (12d) terminates in one land (12a) of the valve spool (12) for fluid communication with the undercut portion (14c) of the valve body (14).
    • 一种具有细长阀体(14)的流体流量控制阀(10),其具有纵向延伸的孔(14a)和形成在其中的多个纵向间隔的径向延伸的端口(14b)。 阀体(14)包括位于两个相邻的径向延伸端口(14b)之间的底切部分(14c)。 在阀体(14)的纵向延伸的孔(14a)内的阀芯(12)可以在行进的第一和第二终点之间移动。 阀芯(12)具有多个平台(12a)和限定流体通道(18)的直径减小的部分(12b),用于与阀体(14)的选择性径向延伸的端口(14b)流体连通,这取决于纵向位置 的阀芯(12)内。 在阀芯(12)中形成有纵向延伸通道(12c)和径向延伸通道(12d)。 径向延伸的通道(12d)终止在阀芯(12)的一个平台(12a)中,用于与阀体(14)的底切部分(14c)流体连通。
