Problems solved by technology

Since the cooling water-conducting cross-section of the individual slats cannot be reduced arbitrarily in order to avoid flow stops and increased friction in the cooling water, only a large amount of compressed air to be cooled can be provided due to the limited installation space in the cylinder head. limited volume
For this reason, further optimization of the heat exchange from the compressed gas to the cylinder head cooling system is not possible in the known embodiments.

Embodiment Construction

[0013] The shown cylinder head essentially comprises a cylinder head upper part 2 and a cylinder head lower part 3 . The intake port 4 and the pressure port 18 are located in the upper part 2 of the cylinder head. The gas to be compressed—due to the downward movement of the piston of the reciprocating piston compressor, not shown—is sucked into the cylinder of the first stage via the suction port 4 via the suction chamber 5, wherein the The suction valve, not shown, is open.

[0014] As a result of the upward movement of the piston, the suction valve is closed and compressed gas enters the pressure chamber 8 of the first stage via the open pressure valve and its pressure valve ports 7 .

[0015] By means of the upward movement of the first piston, the push-out associated therewith, and by the simultaneous downward movement of the second piston and the suction associated therewith, the compressed air is fed into the suction chamber 10 of the second stage through the intercoole...

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).

Description

technical field [0001] The invention relates to a cylinder head for a two-stage reciprocating piston compressor, comprising an intercooler formed as a cooling overflow channel between the pressure side of the first stage and the suction side of the second stage, wherein the overflow The flow channel has a substantially slot-shaped cross section and the overflow channel is additionally separated by at least one indirectly cooled intermediate rib, so that at least two overflow channel parts are thereby formed. Background technique [0002] Nowadays, commercial vehicles such as trucks, buses, construction machines or railway vehicles usually have brakes that can be actuated with compressed air, for their compressed air supply, there is provided a compressor driven by an internal combustion engine serving as the drive of the vehicle, which The compressor often also supplies other subsystems of the vehicle, such as, for example, air springs. Today it is common to integrate the c...
