Abstract
一种滑阀,包括阀体(41)和阀芯(42)。阀体(41)包括多个腔室(A、B1、B2、C1、C2);阀芯(42)在阀体(41)内部并且相对于阀体(41)可移动。阀芯(42)进一步包括轴(12)、在轴(12)上的至少两个肩部(22、24、26、52、54、56)以及至少一个台阶(36、36'、36''、66、68)。至少两个肩部(22、24、26、52、54、56)包括位于最外侧的第一肩部(22、52)和邻近第一肩部(22、52)的第二肩部(24、54),第一肩部(22、52)和第二肩部(24、54)之间形成第一槽(34);至少一个台阶(36、36'、36''、66、68)在第一槽(34)内,至少一个台阶(36、36'、36''、66、68)到第二肩部(24、54)的距离(n)与第一槽(34)的轴向长度(m)的比为15%‑40%。可以防止流体在特定的腔室内滞留,并且引导流体直接流出腔室。
