Title:
NO OILING AIR COMPRESSOR
Document Type and Number:
Japanese Patent JPS58197480
Kind Code:
A
Abstract:
PURPOSE: To prevent wear of a piston and rider-ring by allowing a no oiling piston to be moved in reciprocation by revolution of a crankshaft, thus preventing application of a side-pressure to the piston and the rider ring.
CONSTITUTION: A no oiling piston 4 is allowed to move in reciprocation by revolution of a crankshaft 2, through a connecting rod 13 for allowing an oiling piston 12 to move in reciprocation and a connecting rod 14 for connecting the oiling piston 12 to the no oiling piston 4. Since the reciprocative movement of the no oiling piston 4 is transformed to a linear movement as decsribed in the above, a piston ring 5 and a rider ring 6 are not applied with a side-pressure, and the wear degree is extremely reduced.
