用于凸轮轴的回转马达调整器的液压阀
摘要：
本发明涉及一种液压阀(1)，尤其用于凸轮轴的回转马达调整器，液压阀包括：-套筒(2)，具有在孔(3)中沿着纵向方向(L)可移动地设置的活塞(4)，-供应接头(P)，用于输送液压流体，-至少一个第一工作接头(A)和第二工作接头(B)，以及-至少一个箱流出接头(T1，T2)，用于导出液压流体，第一工作接头和第二工作接头分别配设有止回阀(15，16)，并且第一工作接头和第二工作接头通过活塞的移动经由止回阀中的至少一个能交替地彼此和/或与供应接头和/或与箱流出接头连接。根据本发明，液压阀具有五个接通位置(10，11，12，13，14)，在第一和/或第五接通位置中，在工作接头与箱流出接头之间的相应连接无控制棱边地节流。
摘要（英）：

The invention relates to a hydraulic valve (1), in particular for a pivoting engine adjuster of a camshaft. The hydraulic valve includes a bushing (2) including a piston (4) that is movable in a bore(3) along a longitudinal direction (L); a supply connection (P) configured to feed a hydraulic fluid; at least a first operating connection (A) and a second operating connection (B); and at least a tank drain connection (T1, T2) for draining the hydraulic fluid, wherein the first operating connection and the second operating connection are respectively equipped with check valves (15, 16), and thefirst operating connection and the second operating connection are connectable through at least one of the check valves alternatively with each other or with the supply connection or with the at leastone tank drain connection by moving the piston. According to the invention, the hydraulic valve includes five switching positions (10, 11, 12, 13, 14), and a connection between the operating connections and the at least one tank drain connection in the first/fifth switching position is throttled without control edges.
