Abstract
There is disclosed a high-pressure compressor comprising a compression mechanism for reciprocating/driving a piston with respect to a conventional cylinder by rotation of a motor and compressing an operating fluid sucked by this driving to generate the high-pressure operating fluid according to improvements in a piston shape, positions of a cylinder operation surface and the piston, specifics shapes of the cylinder and piston, and connecting constitution of the piston to a connecting rod, which solves problems such as occurrence of wear on a cylinder inner surface by displacement of the piston, size enlargement by an increase of a removal capacity, difficulty in processing the piston and connecting rod, and a large top clearance.
