发明名称 Level controlling valve for keeping constant automatically the height of a commercial vehicle with pneumatic suspension
摘要 <p>The position of the valve tappet (20) relative to the housing (2) of the level regulating valve (1) is variable via an adjustment drive (6) monitoring the vehicle height and having a guide piece (27) and eccentric cams (10). Via the adjustment drive the end position of a first vehicle height is controllable, in which both the inlet valve (17, 18), and the outlet valve (17, 19) are closed. Aligned with the valve tappet is a control piston (28) which is fed with pressure by a ventilated control chamber (31). By the adjustment of the end position, the control of a second vehicle height is achieved. The guide piece of the adjustment drive is extended towards the side turned away from the inlet seat and is formed into a socket. Between the guide piece and the socket is a tapped hole (99).</p>
