The invention relates to a compressed air supply system for a first compressed air consumer circuit (70, 71), particularly for an air spring system for a vehicle. The compressed air supply system comprises a first compressed air line (14) leading to the first compressed air consumer circuit and a distribution line (18) leading to further consumer circuits (25, 30, 42, 43, 44, 45). A priority valve arrangement (16) is disposed between the first compressed air line (14) leading to the compressed air consumer circuit and the distribution line (18) leading to the further consumer circuits (25, 30, 42, 43, 44, 45), wherein the first compressed air line (14) comprises no safety valve. The first compressed air consumer circuit (70, 71) can therefore be filled at a higher priority, and achieve operational readiness quickly. Air spring processes, for example, such as lifting or raising activities, can be performed very quickly with priority.
A compressed air supply system for a first compressed air consumer circuit, in particular for an air suspension system for a vehicle, which has a first compressed air line (14) leading to the first compressed air consumer circuit (70, 71) and a distributor line (18) leading to further consumer circuits (25, 30, 42, 43, 44, 45), having a priority valve arrangement (16) which is arranged between the first compressed air line (14) leading to the compressed air consumer circuit and the distributor line (18) leading to the further consumer circuits (25, 30, 42, 43, 44, 45), when the first compressed air line (14) does not have a protection valve.
The compressed air supply system as claimed in one of the preceding claims, characterized in that the priority valve arrangement (16) does not have a hysteresis or only has a small or a negative hysteresis.
The compressed air supply system as claimed in one of the preceding claims, characterized in that the priority valve arrangement (16) has a relatively high opening pressure compared to the working pressure of the first compressed air consumer circuit.
The compressed air supply system as claimed in one of the preceding claims, characterized in that at least one first air container (73), which is associated with the first compressed air consumer circuit (70, 71), are connected to the distributor line (18) via a second compressed air line (19, 72).
The compressed air supply system as claimed in one of the preceding claims, characterized by a connecting line (52) between the first compressed air line (14) and a second compressed air line (19, 72) leading to at least a first air container (73).
The compressed air supply system as claimed in one of the preceding claims, characterized by a nonreturn valve (50) between the inlet of the priority valve arrangement (16) and at least one control valve (70) of the first compressed air consumer circuit.
The compressed air supply system as claimed in one of the preceding claims, characterized in that a nonreturn valve (54) is arranged between the protection valve (20) and a second compressed air line (19, 72) leading to at least a first air container (73).
The compressed air system as claimed in one of the preceding claims, characterized in that the priority valve arrangement (16) is embodied as an overflow valve which has a fluid connection (61) which can be connected to the distributor line (18) and can be closed by a valve body (62), a fluid connection (68) which can be connected to the first compressed air line (14), and a valve element (65) which acts as a nonreturn valve.
An air conditioning system, in particular for vehicles, characterized by a compressed air supply system, in particular air suspension system, as claimed in one of the preceding claims.
A method for controlling a compressed air supply system for a first compressed air consumer circuit (70, 71), in particular for an air suspension system, in which firstly the first compressed air consumer circuit (71, 73) is fed, and an air container (73), belonging to the first compressed air consumer circuit (70, 71), of the compressed air consumer circuit is not filled via a priority valve arrangement (16) until after a predetermined time period has passed or a predefined pressure has been attained in the compressed air consumer circuit (70, 71).
