Title:
PISTON BODY CONSTRUCTION OF AIR COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2014/121495
Kind Code:
A1
Abstract:
A piston body construction of an air compressor, comprising a piston head (61). The piston head (61) is provided thereon with a cushioning air-accommodating indentation (60) that has an opening formed from the top, is inwardly indented, and has formed a bottom wall and a sidewall. This allows a piston body (6), while moving reciprocatively in a cylinder of the air compressor, to be kept in a safe pressure value range with respect to an object being inflated, and obviates the need for a pressure valve to be provided additionally.
