Poppet Valves are not tolerant of uneven flow distribution. The poppet valve is usedin a medium pressure range compressor. Nowadays these types of valves are used in
hydrocarbon service because of easy maintenance.
The Figure shows a drilled crankshaft.
Crankshafts should have removable balance weights to compensate the rotary unbalance
as well as reciprocating unbalances. The crankshaft should be dynamically balanced
when above 800 rpm.

The compressor can use narrow piston, due to the use of narrow piston larger valve area for greater efficiency.

Tangent Ring Radial Ring or Pressure Breaker Ring Backup ring.

Tangent Ring切线环
The tangent ring is cut into three segments so that each cut lies on the side of an
equilateral triangle. The cuts of this ring maintain sealing contact regardless of
variations of the ring’s inside diameter. If wear occurs in the tangent ring, the
garter spring will tighten the ring segments to compensate for the wear.
For lubricated service, metallic rings such as cast iron or bronze as well as non-metallic materials such as filled nylon are used. Nowadays the compressor manufacturers preferred non-metallic materials because of less weight and lower frictional force when compared with metallic rings.
