Clearance Volume
Cylinder clearance volume is the
volume of gas left in the cylinder at the discharge end of the stroke.
It includes the space between the piston and cylinder head, the volume
of the valves, valve pockets and any added clearance. Clearance volume
is generally expressed as a percentage of the swept volume of a given
cylinder end.
Changes in the clearance volume
of a compressor cylinder will affect the throughput and power requirements
of that cylinder. Refer to the compressor
theory topic for additional information. Additional clearance can
be added to Ariel cylinders using the following devices:
