Abstract
1. Level-regulating valve for load-dependent pneumatic suspension units in vehicles, with a double seat valve (15, 23, 35) arranged in a housing (20), which double-seat valve (15, 23, 35) connects an external pneumatic suspension bellows (5) to an external air-supply reservoir (2) via an inlet valve (15, 23) and to atomsphere via an outlet valve (15, 35), with the inlet valve seat (23) being designed in the shape of a sleeve and arranged axially adjustably in the housing (20), an a hollow actuating plunger (7 ; 24), which ist axially displaceable in the housing (20), having on one end the outlet valve seat (35), being connected via a follower (12, 25) to an actuating lever (6) and, with the actuating lever (6) in the neutral position, holding the double-seat valve (15, 23, 35) in the closed position, characterized in that the inlet valve seat (35) can be adjusted by a screw-in cover (21), which is arranged on the end face of the housing (20), and against a spring (28) supported on the housing, and that a connection (32) arranged on the housing (20) radially to the housing axis, a channel (34) made in the screw-in cover (21) and an annular groove (33) connecting the connection (32) and the channel (34) are available for connecting to the air-supply reservoir (2).
