First Stage Section
a. Description.
The first stage section
consists of an elbow, gaskets, cylinder head, valve stop,
valve spring, valve plate, exhaust valve, intake valve,
cylinder and piston assembly, and attaching hardware.
The first stage cylinder is provided with a cover and air
cleaners which remove particles of foreign matter from
the ambient air drawn into the compressor. Additional
filtering is provided by a strainer and relief valve
assembly installed in the inlet port of the second stage
cylinder. Fine mesh screens installed in the body of the
strainer and relief valve assembly trap solid particles in
the interstage air, and spring-loaded poppets function as
pressure relief valves to prevent interstage air pressures
from exceeding predetermined values. The intake and
exhaust valves used in the first stage of the air
compressor are spring steel flapper-type valves mounted
