Reciprocating compressor used in a braking system of a vehicle comprises working cylinders sealed from each other in the region of a piston rod by a seal in the form of an axial gap seal

摘要

Reciprocating compressor (1) comprises working cylinders (2, 4) sealed from each other in the region of a piston rod (10) by a seal in the form of an axial gap seal (66) formed between a radial outer peripheral surface of the piston rod and a radial inner peripheral surface of a through opening (32). An independent claim is also included for braking system of a vehicle actuated by compressed air an containing the above reciprocating compressor. Preferred Features: The radial inner peripheral surface of a through opening is provided with radial grooves (68) arranged at an axial distance from each other.
