A double-piston compressor of a compressed air supply device. The double-piston compressor includes a low pressure stage and a high pressure stage, each of the low pressure stage and the high pressure stage having a cylinder with a piston guided in an axially movable manner therein. A piston of the cylinder of the low pressure stage and a piston of the cylinder of the high pressure stage are drivingly connected to the drive shaft via a sliding block guide. Sliding block tracks of the sliding block guide are constructed and arranged such that, during operation of the double-piston compressor, a movement of the pistons follows a stroke curve that deviates from a regular sinusoidal stroke curve, which has an amplitude corresponding to an eccentricity of the drive element.

A compressed air supply installation for operating an air suspension installation of a vehicle includes an air supply unit configured to supply air, an air compression unit configured to compress air, a bleeding line, and a compressed air supply line. The bleeding line includes a bleeding valve arrangement in the form of a controllable solenoid valve arrangement comprising a magnetic part and a pneumatic part actuatable directly via the magnetic part, and a bleeding port for bleeding air. The compressed air supply line includes an air dryer, and a compressed air port for supplying the pneumatic installation with compressed air. The pneumatic part is open in an unactivated state of the magnetic part of the solenoid valve arrangement. The pneumatic part is open in a branch line of the compressed air supply line between a pressure-side valve port and a control-side valve port of the branch line.
摘要:
A compressed air supply unit for operating a pneumatic unit by means of a compressed air flow, in particular of an air suspension unit of a vehicle, comprises an air dryer arrangement in a main pneumatic line that pneumatically links a compressed air feed line from an air compressor and a compressed air connection to the pneumatic unit. A valve arrangement is pneumatically connected to the main pneumatic line for controlling the compressed air flow. The air dryer arrangement has a drying container having a container outer wall. A partition along a length of the drying container divides an internal space delimited by the container outer wall into first and second chambers delimited by the partition and the container outer wall. The partition adjoins the container outer wall along the length of the drying container, and the first and second chambers are adjacent to one another along that length.
