Laterally moveable compressor piston rod lip seal assembly

A piston rod lip seal assembly comprising:

• a lip seal comprising a first circumferential lip configured to seal an inner diameter of the lip seal, and a second circumferential lip configured to seal an outer diameter of the lip seal, wherein the piston rod lip seal assembly is configured for lateral motion of a piston rod within a housing component, and the lateral motion is perpendicular to an axis of the piston rod;
• a heel;
• a spring;
• and
• a seal carrier disposed around, and in contact with, the second circumferential lip of the lip seal, wherein
• the spring is disposed between, in contact with, and secured by the first circumferential lip and the second circumferential lip,
• the seal carrier is further disposed around, and in contact with, the heel, and
• the seal carrier further comprises a protrusion configured to retain the lip seal axially.
