| 摘要 |
The invention relates to a valve, in particular a pilot-operated proportional directional poppet valve, having a valve housing (7) which has a fluid inlet (21) and a fluid outlet (23), wherein the fluid stream between the fluid inlet (21) and the fluid outlet (23) is adjustable by a main piston (27), wherein a pilot valve chamber (37) provided on a rear face (29) of the main piston (27) has a pilot valve closing member (33) which can be moved by an actuating device (69) and by which the fluid stream between the pilot valve chamber (37) and the fluid outlet (23) can be adjusted, wherein an inlet aperture (3) is arranged between the fluid inlet (21) and the pilot valve chamber (37), characterised in that a maximum volumetric flow controller (5) is provided in the main piston (27) in an outflow between the pilot valve chamber (37) and the fluid outlet (23). |
