Description

Technical Field

[0001] The present invention relates to a gas compressor, in particular to a light and portable gas compressor. Background Art

[0002] The function of the well-known gas compressor is to use mechanical energy to compress gas. Commonly used ones are piston type with reciprocating compression and screw type with dual rotor meshing compression. Among them, the piston type is currently the most common. The principle of the piston type is that the crankshaft is driven by a motor, and multiple piston rods connected to the crankshaft drive a gas compression cylinder respectively, and then the gas is allowed to pass from the first compression cylinder through a pipe and a one-way valve into the second compression cylinder, and the second compression cylinder then passes through a pipe and a one-way valve to enter the third compression cylinder, and the third compression cylinder then passes through a pipe and a one-way valve to enter the fourth compression cylinder, and the fourth compression cylinder then passes through a pipe and a one-way valve to enter the fifth compression cylinder, and the fifth compression cylinder then passes through a pipe and a one-way valve to enter the sixth compression cylinder and then enters the equipment through a pipe, so that the equipment obtains multi-stage compressed gas; this method requires multiple compression cylinders to be connected to the motor through a crankshaft as a whole, which is not only bulky and difficult to move when used, but is also very inconvenient, especially for use in small spaces or high-altitude power equipment, in military fields, and on ships.
