Title:
COMPRESSOR AND PUMP UP DEVICE
Document Type and Number:
Japanese Patent JP2006105045
Kind Code:
A
Abstract:

To provide a reciprocating compressor for reducing resistance to reciprocation of a piston, and for compressing air to generate high-pressure air and discharging the air, and to provide a pump up device provided with the compressor.

A plurality of grooves 114 are formed in an inner face of a cylinder 86 along a reciprocation direction of the piston 102. Since the grease as lubricant is piled up in the grooves 114, lubrication effect is maintained even after a lapse of many hours. Since the grooves 114 are formed to narrow a substantial contact area of packing 112 with respect to the inner face of the cylinder 86, sliding resistance in the reciprocation of the piston 102 is smaller than the constitution with no groove.
