Abstract: A suspension control valve arrangement for a pneumatic suspension system of a commercial vehicle includes a supply port, a delivery port, an exhaust port, a service valve arrangement, and an operation control mechanism (5, 6) for switching the service valve arrangement into one of the following normal operation modes of a normal operation status: a blocking position for a blocking mode for blocking an air supply from the supply port to the delivery port, a supply position for a supply mode for supplying air from the supply port to the delivery port, or an exhaust position for a normal exhaust mode for connecting the delivery port to the exhaust port. A dump-control device (7, 11) in the housing (2) is configured for switching between the normal operation status and a quick-dump mode (IV), win which the delivery port is connected to the exhaust port by bypassing the service valve arrangement.

Abstract: An air suspension control system (ECAS, electronic controlled air suspension) (10) for a utility vehicle, such as a truck or the like, or for a passenger car, includes a main control unit (12) for operating the air suspension control system (10)and at least two auxiliary control units (14) connected to the main control unit (12) via a data link (16). The auxiliary control units (14) each have at least one output (18) for actuating at least one actuator (20) which can be connected to the output (18), in particular an adjustment drive (28) for a valve (30). Furthermore, at least one function for generating control signals at the output (18) can be stored in the auxiliary control units (14), and the main control unit (12) is adapted to call up and/or to parameterize at least the stored functions by transmitting commands via the data link (16).

Abstract: An air control valve (100) adapted to control an air flow (FA) for an air cushioning receptacle (802) in a motor vehicle (1000) includes a valve seat (120), a valve body (110), and a valve passage element (105) with a passage inlet (140) on an inlet side (141) and a passage outlet (150) on an outlet side (151). A coil spring (160) in contact with the valve body (110) and with a valve stop (152) on the outlet side (151) is adapted to exert a closing force (FC) to press the valve body (110) to the valve seat (120). A damping body (200) is arranged in an inner spring space (161) of the coil spring (160) such that the damping body (200) radially extends in a winding space (162) between a first coil winding (163) and a second coil winding (164) of the coil spring (160).

Abstract: A leveling valve (101) for discharging and supplying air from and to a plurality of utilization elements (205a, b), in particular pneumatic suspension bellows, includes a valve arrangement (103) for directing air between a source (207) of pressurized air, an exhaust port (3) and the utilization elements, a supply port (1) in fluid communication with the valve arrangement (103) and the source (207) of pressurized air, and an exhaust port (3) having an exhaust air channel (a) for discharging exhaust air. The exhaust port (3) includes at least one air-permeable damping element, which is at least partly positioned within the exhaust air channel (a).
