1. General
Each cylinder cover is provided with an indicator valve combined, depending on
Class requirements, with a relief valve, which is connected by relief bore ’RB’ to the
compression chamber. An inadmissible high pressure peak in the compression
chamber opens the valve and the over-pressure is immediately reduced.
A relief valve which has blown off or valves leaking during engine operation
must be replaced at the first opportunity (with engine stopped only).
A relief valve can not be repaired nor adjusted any more after having blown-
off!
Relief valves require no maintenance, however they should be checked in general
at every major engine overhaul. Basically leaking or damaged valves should be
returned to the manufacturer for inspection and repair.
