| 摘要 |
The present invention relates to a slide valve (10) comprising a valve slide (14) having at least one control edge at a slide side (34); a housing (12); and at least two oil pressure connection parts (18, 20) arranged in the housing (12) and spaced apart in an axial direction. The valve slide (14) has a central axis (16) and the valve slide can move in the housing (12) along the central axis. At least one among the oil pressure connection parts (18, 20) includes control edges at a housing side (28, 30), which cooperates with the control edge at a slide side (34). The connection parts (8, 20) can be connected or separated by the valve slide (14) using oil pressure. According to the present invention, at least one hole (22, 24) is formed on the control edges at a housing side (28, 30). And the central axis (22a, 24a) of the hole (22, 24) extends perpendicularly or obliquely with respect to the central axis (16) of the valve slide (14) but does not intersect with the central axis (16) of the valve slide (14). |
