11 - B - CYLINDER HEADS & VALVES
The G05 compressor's intake and compression valves are made of annular discs which run
automatically.
Good water-tightness is necessary between the discs and their seats (avoid running the compressor
with clogged valves, with carbon deposits, oil carbon or more importantly, with broken valves).
In order to limit the number of parts, ERVOR use two types valves.
