Abstract
A valve arrangement for reciprocating machine, where the arrangement () comprises 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 the cylinder head of the reciprocating engine (). The in-valve () and the out-valve () are mounted in a 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 () via the in-valve (), and where 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 ().
