Cylinder head for a two-stage reciprocating piston compressor

Abstract

The invention relates to a cylinder head (1) for a two-stage reciprocating piston compressor, comprising an intercooler (9) that is designed as a cooled overflow channel (14) between the pressure side of the first stage and the suction side of the second stage, wherein the overflow channel (14) has a substantially slot-like cross-section, and the overflow channel (14) is in addition divided by at least one indirectly cooled center rib (15) so that therefrom at least two overflow channel portions (14′) and (14″) are created, wherein the cylinder head (1) has a cylinder head upper part (2) and a cylinder head lower part (3), the cross-section of the indirectly cooled center rib (15) is divided in its longitudinal extent thereby forming a passage gap between the overflow channels (14′) and (14″) that run on both sides, and one portion of the center rib (15) is formed from the cylinder head upper part (2) and the other portion of the center rib (15) is formed from the cylinder head lower part (3).
