Improvements relating to gas compressor apparatus |
(57) In a single cylinder piston and cylinder air compressor, transmission noise and stresses
are reduced by a valve arrangement (16,21) driven by an excentric (14) of the compressor
crankshaft to vent the compression chamber at or near its minimum volume thereby reducing
the cyclic torque reversal which occurs.
