Valve for Variable Throttling of a Hydraulic Flow with a Fatigue-Resistant Mechanical Means for Reducing Possible Valve Oscillations

A valve (1) for variable throttling of a hydraulic flow includes a tappet (2) and a guide element (3) in which the tappet (2) is guided for movement in a stroke direction (4). The valve also includesat least one fatigue-resistant, mechanical member (5) that locally reduces a radial play (6) of the t...

Beschreibung
Zusammenfassung:	A valve (1) for variable throttling of a hydraulic flow includes a tappet (2) and a guide element (3) in which the tappet (2) is guided for movement in a stroke direction (4). The valve also includesat least one fatigue-resistant, mechanical member (5) that locally reduces a radial play (6) of the tappet (2) so as to reduce possible valve oscillations. 本发明涉及一种用于液压流的可变的节流的阀门(1)，包括挺杆(2)和引导元件(3)，挺杆(2)在该引导元件中引导，以沿行程方向(4)运动，其特征在于，设有至少一个抗疲劳的机械式器件(5)，其局部减小挺杆(2)的径向游隙(6)，以减小可能的阀门振动。
