AI Technical Summary
Technical Problem
Existing radial piston compressors suffer from contact gaps and fluctuations due to production tolerances, leading to noise, increased friction, and wear due to the inflexible nature of the piston guide ring, which fails to maintain constant contact with the eccentric.
Method used
The piston guide ring is designed to be at least partially elastic, allowing it to deform and maintain contact with all contact points, compensating for tolerances and fluctuations in diameter, thereby ensuring constant contact with the eccentric.
Benefits of technology
This design reduces noise and wear by maintaining consistent contact, improving kinematic dynamics and reducing friction, thus enhancing the operational performance of the radial piston compressor.

Abstract
A radial piston compressor comprises a compressor unit and a drive device for driving the compressor unit, wherein the compressor unit includes at least two piston-and-cylinder-bore assemblies, preferably a plurality of piston-and-cylinder-bore assemblies, which are arranged radially around an eccentric shaft, wherein the eccentric shaft is driven by the drive device, wherein each piston-and-cylinder-bore assembly includes a piston, wherein the radial piston compressor, in particular the compressor unit, includes a piston guide ring, wherein the pistons are in contact, in particular in positive engagement, with the piston guide ring, wherein the piston guide ring is elastic, in particular elastic in the radial direction, at least in parts, preferably completely.
