Embodiment Construction

[0018] The drawing shows a schematic diagram of a pneumatic door control system with a compressor 1 for generating compressed air, a cylinder 2 for actuating a door, an air dryer 3 and a door control valve 4 . The cylinder 2 has a first cylinder chamber 8 and a second cylinder chamber 9 which are separated from one another by a cylinder piston 13 which is movably arranged in the cylinder 2 . The cylinder piston 13 can, as intended, assume a first functional position O and a second functional position X, wherein the cylinder piston 13 assumes the second functional position X as soon as the first cylinder chamber 8 is pressurized. The cylinder piston 13 is in the first functional position O when the second cylinder chamber 9 is pressurized.

[0019] Switching between the first functional position O and the second functional position X is effected by changing the first switching position A and the second switching position B of the gate control valve 4 . In the illustration show...

Abstract

The invention relates to a door controller for vehicles, comprising a compressor (1), an air drier (3), a door control valve (4), and at least one cylinder (2) that can be actuated by means of compressed air. The invention further relates to a method for actuating a cylinder (2) of a vehicle door, wherein a cylinder piston (13) of the cylinder (2) can assume a first functional position (O) and a second functional position (X). In the drying mode the air flowing into the cylinder (2) flows through the air drier (3), and in the regeneration mode the air flowing out of the cylinder (2) flows through the air drier. The cylinder (2) is loaded only with compressed air from a compressed-air accumulator (7).

Description

technical field [0001] The invention relates to a pneumatic door control device for a vehicle having a compressor, an air dryer, a door control valve and at least one cylinder actuatable with compressed air. The invention also relates to a method for actuating a door cylinder, wherein a cylinder piston of the cylinder can assume at least a first and a second functional position. Background technique [0002] A pneumatic door control device is known from DE 10 2008 011 315 A1, which has a double-acting cylinder connected to the door, the two cylinder chambers of which are connected via valves to a compressor. When the cylinder is exhausted, the compressed air is reduced to atmospheric pressure. [0003] Usually, the compressed air generated by the compressor is dehumidified in an air dryer, since the dry compressed air has a higher quality, which also has a positive effect on the service life of the pneumatic system. Such air dryers must periodically remove moisture manuall...
