Compressor, Clarion
The compressor is of the swash-plate type. It is
also of the reciprocating type and has ten hori-
zontal cylinders with double-acting pistons. The
valve system comprises individual swash plates
located between the compressor housing and
the cylinder heads. The valves are opened and
closed by the pressure differences created by
the action of the pistons. Service valves for the
system are incorporated in the rear cylinder head
of the compressor.
Caution
The compressor has an oil filler plug which
must be removed unless the system has
been drained of refrigerant. N.B. The plug
cannot be used for checking the oil level.
