摘要： A compressed-air feed system for operating a pneumatic system includes a compressed-air supply, a compressed-air connection to the pneumatic system, a ventilation connection to surroundings, and a pneumatic main line between the compressed-air supply and the compressed-air connection. The pneumatic main line has an air dryer and a regeneration throttle. The compressed-air feed system further includes a ventilation line between the pneumatic main line and the ventilation connection. The ventilation line has a ventilation valve and a ventilation throttle. The compressed-air feed system further includes a bypass line between the compressed-air connection and the air dryer. The bypass line has a bypass valve formed as a 2/2 directional valve configured to permit an air flow conducted via the air dryer, and bypassing the regeneration throttle, for filling and ventilating the pneumatic system.

摘要： A compressed-air feed system for operating a pneumatic system includes a compressed-air supply, a compressed-air connection to the pneumatic system, at least one ventilation connection to surroundings, and a pneumatic main line between the compressed-air supply and the compressed-air connection. The pneumatic main line has an air dryer and a regeneration throttle. The compressed-air feed system further includes a first ventilation line between the pneumatic main line and the at least one ventilation connection. The first ventilation line has a first ventilation valve and a ventilation throttle. The compressed-air feed system additionally includes a second ventilation line between the compressed-air connection and the at least one ventilation connection. The second ventilation line has a second ventilation valve formed as a 2/2 directional valve. The compressed-air feed system is designed to provide an operating mode in which the second ventilation valve is open over a predetermined time period.

摘要： A reciprocating piston machine includes a first cylinder and a first piston assigned to the first cylinder and a second piston assigned to the first cylinder or a second cylinder. The reciprocating piston machine further includes a crankshaft having an eccentric crankshaft journal and a drive shaft coupling configured for coupling a drive shaft of a drive motor for driving the crankshaft, a first connecting rod configured to deflect the first piston and configured to be moved by the eccentric crankshaft journal, and a second connecting rod configured to deflect the second piston and configured to be moved by a bearing pin. The reciprocating piston machine additionally includes at least one of a first elastomer element arranged between the bearing pin and the first connecting rod and a second elastomer element arranged between the bearing pin and the second connecting rod.
