Device for controlling pressurized fluid flow rates in a vehicle suspension

Device for controlling the flow rate of pressure fluid in a supply line for the cylinder chambers of spring cylinders on vehicles with permanently suspended and level-controlled axles via level control devices, in particular on tractors, wherein a throttle for limiting the flow rate of the pressure fluid is inserted into the supply line, wherein the supply line (2) is provided with a bypass line (15) bypassing the throttle (4), into which an additional throttle (16) controlled by a control device (17) with a height sensor is inserted, which is switched on upon reaching the end stops of the vehicle axle after severe static load changes and permits a greater flow rate of the pressure fluid.
