Background

Currently, a large part of the existing gas compressors is a positive displacement gas compressor, which works by tightly closing a fixed amount of gas in a compression chamber, mechanically reducing the volume occupied by the gas to compress the gas, and outputting the compressed gas. The gas pressure increase corresponds to a volumetric decrement of the space occupied by the same amount of gas. The term "gas" as used in this specification includes gaseous substances, liquid substances or mixtures of liquid and gaseous substances, positive displacement compressors mostly use rotating parts that mechanically reduce the volume occupied by the gas, often using driving means to drive a rocker arm with a reciprocating movement of a piston that will sweep a portion of the compression chamber each time the piston moves into the compression chamber, thereby reducing the volume of the compression chamber occupied by the gas and increasing the pressure therein. The compressed gas then leaves the compression chamber, the piston is extracted from the compression chamber and the gas to be pressurized is sucked into the compression chamber for the subsequent reciprocating movement of the piston, which reciprocating compressors using piston compression have some disadvantages, such as the high inertia forces associated with the reciprocating parts in the compressor equipped with a piston, the compressor drive accelerating the piston in one direction, stopping it and then accelerating it in the opposite direction in a continuous reciprocating movement, the larger the piston assembly, the greater the force that the drive needs to provide to accelerate and decelerate the assembly, the lower the compressor efficiency since the kinetic energy of the assembly is usually dissipated at the end of the stroke. This energy loss is particularly severe in compressors with short piston strokes, and therefore the majority of the force generated by the compressor drive is not used to compress the gas, but is consumed in the process of continuously accelerating the piston assembly; to this end, an application number has also been proposed: 201380025455.2, compressor patent application entitled electromagnetic actuator and inertial retaining device for a reciprocating compressor, which proposes a reciprocating compressor solution comprising: a piston reciprocatably disposed within the compression cylinder; a translatable assembly connected to the piston; an electromagnetic drive having a stationary stator and a core coupled to the translatable assembly, wherein the drive is configured to reciprocally drive the translatable assembly within the compression chamber; and an accumulator connected to the translatable assembly, wherein the accumulator is configured to store kinetic energy residing in motion of the translatable assembly in a first direction, and wherein the accumulator is configured to transfer kinetic energy residing in motion of the translatable assembly in a second direction; in addition, there is an application No.: 201910311667.6, entitled compressor patent application for a bi-directional electromagnetically driven air compressor, which proposes the following: the utility model provides a two-way electromagnetic drive air compressor, piston in cylinder body and the cylinder body including the cylinder type, all be provided with the cylinder cap on the opening at cylinder body both ends, all be provided with the intake duct that has the check valve that admits air, the ventiduct and the electromagnetic drive ware of the check valve that gives vent to anger on every cylinder cap, the piston rod of connection on the piston stretches out and extends to the electromagnetic drive ware that corresponds from the cylinder cap at cylinder body both ends in, the reciprocating motion of syntropy application of force drive piston rod and piston behind the electromagnetic drive ware circular telegram of cylinder body both sides to make and admit air from the intake duct, export compressed gas from.
