CYLINDER ASSEMBLE STRUCTURE FOR COMPACT AIR COMPRESSOR

WIPO Patent Application WO/2018/212452

A1

A cylinder coupling structure of a compact air compressoraccording to the present invention comprises a block, a tubular-shaped cylinder assembled to the block, a valve cover which covers the valve assembly so as to form a suction space and a discharge space at the top of the valve assembly, at least one pressurized bolt which assembles the valve cover and the block so that the cylinder can be pressurized between the valve cover and the block, a piston which is reciprocated inside the cylinder, a stator which is assembled to the block, a rotator which is located to relatively rotate as to the stator, a crank axis which is assembled to the rotator to integrally rotate with the rotator to be axially supported in the block to be rotatable, and a connecting rod, each of both ends thereof is connected to the crank axis and the piston, respectively, so as to convert a rotational movement of the crank axis into a straight reciprocating movement of the piston, characterized in that the piston has the O-ring inserted into the ring insertion end formed at the front end part and has fixing rings inserted intothe ring insertion end at the outer side of the O-ring to be coupled to the piston.
