The invention provides an ultrahigh-pressure
air compressor. The defects that a traditional ultrahigh-pressure
air compressor is heavy and low in efficiency can be overcome, and the ultrahigh-pressure
air compressor is miniaturized and high in reliability. The ultrahigh-pressure air compressor comprises multiple air cylinders, multiple corresponding pistons, multiple double-acting connecting rods and a
swash plate. The double-acting connecting rods are arranged in the working direction of the air cylinders, one
piston is arranged at one end of each double-acting connecting rod, the other end of each double-acting connecting rod is connected with the
swash plate playing a role in driving, and the
swash plate is used for driving the double-acting connecting rods to move in the working direction. The number of the swash plate is one, and the swash plate is arranged obliquely relative to the working direction in an
acute angle or obtuse angle mode. The double-acting connecting rods and the air cylinders are symmetrically arranged in parallel on the two sides of the swash plate respectively. An
exhaust valve of the next level of air cylinder adjacent to each level of compression air cylinder is connected with an air
inlet valve of the last level of air cylinder adjacent to the compressor air cylinder in series, and the exhaust value of the most upstream air cylinder of a flow channel is connected with the air
inlet valve of the air cylinder in series.
