Beschreibung
Zusammenfassung:	A hydraulic overpressure valve (1) is provided comprising a valve housing (2), a valve seat (3) located in said valve housing and having a seat center and a seat center axis (4), a cone element (5) movable relatively to said valve seat (3), said cone element (5) having a cone (6) protruding at least partly into said valve seat (3) and having a cone center axis (4), and force generating means acting on said cone element (5) in a direction towards said valve seat (3). Such a hydraulic overpressure valve should be operated with low noise. To this end said cone (6) is movable along a path of movement in which said cone center axis is kept outside said seat center axis (4). 提供种液压过压阀(1)，所述液压过压阀包括阀壳体(2)、定位在所述阀壳体中并且具有座中心和座中心轴线(4)的阀座(3)、能够相对于所述阀座(3)移动的锥体元件(5)、和在朝所述阀座(3)的方向上作用在所述锥体元件(5)上的力生成装置，所述锥体元件(5)具有至少部分地突出进入所述阀座(3)并且具有锥体中心轴线(4)的锥体(6)。该液压过压阀应该在低噪声的情况下被操作。为此所述锥体(6)可沿着移动路径移动，在所述移动路径中，所述锥体中心轴线被保持在所述座中心轴线(4)外侧。
