Embodiment Construction
[0018] figure 1 The illustrated valve device 10 consists of a valve body 12 , which is formed with a valve bore 14 , and a valve member 16 , in which the valve member is accommodated so as to be displaceable in the axial direction. The valve bore 14 is offset once inwards on its inner diameter and forms a valve seat 18 around a throttle cross section 20 . The valve seat 18 is formed, for example, as an inner cone, but it can also be embodied as right-angled or rounded.
[0019] As indicated by the drawn flow arrow S, the pressure medium is based on figure 1 The illustration in , flows through the throttle cross-section 20 from bottom to top. The valve member 16 is thus arranged downstream of the throttle cross section 20 in the valve bore 14 . In the shown flow state of the valve device 10 , the valve member 16 is lifted from the throttle cross section 20 , so that the valve member 16 is surrounded by pressure medium over its entire circumference. The outlet of the valve d...
