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。
