Problems solved by technology

Added to this are restrictions in the casting of the cylinder heads, making it difficult for narrow cooling cross sections to be formed by correspondingly delicate casting cores.
This is disadvantageous in respect of the further processing of the compressed air, in particular for drying of the air.
This results in the necessity of having to cool the air between the compressor and the air fil

DETAILED DESCRIPTION OF THE DRAWINGS

[0026]According to FIG. 1, a compressor 2 comprises a cylinder head 1 and a piston housing 8, wherein a valve plate 9 is arranged between the piston housing 8 and the cylinder head 1. The compressor 2 is driven via a shaft 10. The piston housing 8 is cut open in the vicinity of the valve plate 9 such that a piston chamber 11 is visible. A piston (not illustrated here) moves axially up and down in the interior of the piston chamber 11.

[0027]According to FIG. 2, the cylinder head 1 has four coolant-conducting regions 3a-3d and two air-conducting regions 4a, 4b. The four coolant-conducting regions 3a-3d are substantially arranged about the two air-conducting regions 4a, 4b, wherein the four coolant-conducting regions 3a, 3b are directly adjacent to the air-conducting region 4a in order to cool down the compressed air. Coolant-conducting ducts (not illustrated here) also penetrate the valve plate 9 in a meandering form.

[0028]The two air-conducting reg...

Abstract

A cylinder head is provided for a compressor, including at least one coolant-conducting region and at least two air-conducting regions. The at least one coolant-conducting region is arranged at least partially around the at least two air-conducting regions. The at least two air-conducting regions have at least one air-feeding duct for feeding the air to be compressed into the compressor and at least one air-discharging duct for outputting a compressed air which is compressed by the compressor. The at least one air discharging duct includes an open-pore, metallic cell structure.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of PCT International Application No. PCT / EP2015 / 066375, filed Jul. 17, 2015, which claims priority under 35 U.S.C. §119 from German Patent Application No. 10 2014 111 527.9, filed Aug. 13, 2014, the entire disclosures of which are herein expressly incorporated by reference.BACKGROUND AND SUMMARY OF THE INVENTION[0002]The invention relates to a cylinder head for a compressor, including at least one coolant-conducting region and at least two air-conducting regions, wherein the at least one coolant-conducting region is at least partially arranged around the at least two air-conducting regions. Furthermore, the at least two air-conducting regions have at least one air-supplying duct for feeding the air to be compressed into the compressor and at least one air-discharging duct for outputting compressed air compressed by the compressor.[0003]Modern commercial vehicles which are used in rail or road traffic are...
