Compressors with improved sealing assemblies

A sealing assembly between a first component and a second component of a compressor with a cylinder having an inlet and an outlet, comprising:

• a ring seal between the first component and the second component at the outlet of the compressor;
• a vent port defined by the first component and at least partially sealed by the ring seal from air compressed within the cylinder;
• and
• a vent tube extending between the vent port and the inlet such that any portion of the air that leaks through the ring seal flows through the vent port, through the vent tube, and into the inlet.

A compressor, comprising:

• a housing;
• a compressor liner positioned within the housing and at least partially defining first, second, third and fourth cylinders, each of the cylinders having an inlet and an outlet, and the cylinders respectively corresponding to first, second, third, and fourth stages of compression;
• a cylinder head at least partially defining the fourth cylinder;
• and
• a sealing assembly for sealing an interface between the compressor liner, the cylinder head, and the housing, the sealing assembly comprising:
• a c-seal at an interface between the cylinder head and the compressor liner;
• a vent port on an opposite side of the c-seal from the fourth cylinder;
• and
• a vent tube extending between the vent port and the inlet such that air leaking through the c-seal from the fourth cylinder flows through the vent port, through the vent tube, and into the inlet of the fourth cylinder.
