Abstract:
1. A valve arrangement for a reciprocating machine, the arrangement comprising: an in-valve and an out-valve, each valve being a springloaded one-way valve designed to open for flow when the pressure differential in the direction of flow provides a force that exceeds the spring tension, wherein the valves are mounted in a casing that forms or is connected to a cylinder head of the reciprocating machine, wherein the in-valve and the out-valve are mounted in one common sleeve designed to be fitted in a bore in the casing, and where fluid may flow to the sleeve from an inlet in the casing and into the sleeve is provided with at least one perforated area where fluid may flow radially out of or into the sleeve via holes, thereby flowing to or from a passage that forms a perpendicular or near perpendicular connection with the bore, wherein the bore is provided with at least one eccentrically positioned cylindrical section with a larger diameter than that of adjacent sections of the sleeve, and where the eccentrically positioned section communicates with said passage.
