Lubricant-Free Compressor Having a Graphite Piston in a Glass Cylinder

摘要

A substantially lubricant-free compressor comprising a glass cylinder having a hollow interior, a graphite piston within the glass cylinder, a connecting rod operably attached to the graphite piston, a cylinder head sealing one end of the glass cylinder, an exhaust valve in operable connection with the hollow interior of the glass cylinder, and an inlet valve in operable connection with the hollow interior of the glass cylinder. The compressor may be driven by any suitable means including without limitation a brushless DC motor or a smart material actuator.

1. A compressor comprising
a glass cylinder having a hollow interior, a graphite piston within the glass cylinder, a connecting rod operably attached to the graphite piston, a cylinder head sealing one end of the glass cylinder and comprising an exhaust valve in operable connection with the hollow interior of the glass cylinder, and an inlet valve in operable connection with the hollow interior of the glass cylinder,wherein upon the connecting rod moving the graphite piston toward the cylinder head, material within the hollow interior of the glass cylinder is compressed until a sufficient pressure is attained to expel a portion of the material out the exhaust valve, and upon the connecting rod moving the graphite piston away from the cylinder head, material is drawn into the hollow interior of the glass cylinder through the inlet valve.
