Embodiment Construction

[0101] figure 1 In detail D is shown an air compressor with a reciprocating piston machine in the form of a two-stage piston compressor 400 with a first compressor stage 401 and a second compressor stage 402, the second compressor The stages are driven via a motor 500 as a drive motor M.

[0102] Such a piston compressor 400 is preferably used in a pneumatic compressed air supply system 1000, for example in figure 1 as shown in.

[0103] figure 1 A pneumatic circuit diagram of a pneumatic compressed air supply system 1000 is shown, which has a compressed air supply system 1001 with an air dryer installation 100 and a pneumatic system 1002 in the form of an air spring system. The compressed air supply device 1001 is used to operate the pneumatic device 1002 .

[0104] The compressed air supply 1 is currently formed with an air supply 0 , an air filter 0.1 arranged upstream of the air supply 0 , and an air compressor driven via a motor 500 arranged downstream of the air supp...

Abstract

A reciprocating-piston machine includes at least one first cylinder and at least one first piston assigned to the first cylinder as well as at least one second cylinder and at least one second piston assigned to the second cylinder. During operation, the first piston and the second piston are deflected in a respective cylinder displacement chamber of the respective first cylinder and the second cylinder. The reciprocating-piston machine further includes a crankshaft which, during operation, can be driven and which has an eccentric crankshaft journal and a drive shaft coupling designed for the coupling of a drive shaft of a drive motor for driving the crankshaft. Additionally, the reciprocating-piston machine includes a first connecting rod configured to deflect the first piston, a second connecting rod configured to deflect the second piston, and a bearing pin about which the first and second connecting rod are rotationally movable.

Description

technical field [0001] The invention relates to a reciprocating piston machine, especially a two-stage or multi-stage piston compressor. The invention also relates to a compressed air supply system, a compressed air supply system and a vehicle, in particular a passenger car, with a reciprocating piston machine, in particular with a piston compressor. Background technique [0002] Compressed air supply systems are used in all types of vehicles in particular to supply compressed air to air spring systems of passenger cars or commercial vehicles. The air spring system can also include a leveling device with which the distance between the axle and the body can be set. The air spring device of the pneumatic compressed air supply system mentioned at the outset consists of several air bellows pneumatically coupled to a common line (channel), which raise the bodywork as the filling increases and correspondingly lower as the filling decreases bodywork. Such systems are preferably ...
