Abstract: A pneumatic cylinder includes a cylinder housing, a central piston displaceable longitudinally in the cylinder housing, a first trailing piston configured to work with a first trailing stop of the central piston and a first positioning stop on the cylinder housing, and a second trailing piston configured to work with a second trailing stop of the central piston and a second positioning stop on the cylinder housing. The cylinder housing comprises a base body in which the first trailing piston runs, a cylinder cover in which the second trailing piston runs, and an intermediate washer on which the first positioning stop and the second positioning stop are formed.

Abstract: The invention relates to a pressure control device (7, 8, 9, 18, 22, 23, 24, 57, 58, 60, 70, 71, 80, 81, 82, 90) for a vehicle (100), wherein the vehicle (100) comprises at least one drive motor (101) for producing a driving force of the vehicle, a compressed-air supply and storage system (12), and an air compressor (1) that is or can be coupled to the drive motor (101) of the vehicle, and the pressure control device (7, 8, 9, 18, 22, 23, 24, 57, 58, 60, 70, 71, 80, 81, 82, 90) comprises at least one electronic control unit (18) and at least one valve device (7, 8, 9, 23, 24, 57, 58, 60, 70, 71, 80, 81, 82, 90) for controllably connecting a compression chamber (4) of the air compressor (1) to the compressed-air supply and storage system (12), wherein the pressure control device has the following characteristics: a) the pressure control device (7, 8, 9, 18, 22, 23, 24, 57, 58, 60, 70, 71, 80, 81, 82, 90) is designed to connect the compression chamber (4) to the compressed-air supply and storage system (12) in

Abstract: The invention relates to a pneumatic cylinder (10) having a cylinder housing (12), a central piston (16) displaceable longitudinally in the cylinder housing (12), a first trailing piston (18) designed for working together with a first trailing stop (30) of the central piston (16) and a first positioning stop (44) on the cylinder housing (12) and a second trailing piston (20) designed for working together with a second trailing stop (32) of the central piston (16) and a second positioning stop (46) on the cylinder housing (12). According to the invention, the cylinder housing (12) comprises a base body (24) in which the first trailing piston (18) runs, a cylinder cover (28) in which the second trailing piston (20) runs, and an intermediate washer (26) on which the first positioning stop (44) and the second positioning stop (46) are formed.
