specific Embodiment approach

[0026] Specific implementation: as figure 1 As shown, a multi-cylinder gas compressor includes a cylinder block 8, wherein an intermediate frame body 9 is provided in the middle of the cylinder cavity (the intermediate frame body can be a frame structure surrounded by four sides or also It can be a closed box structure), the middle frame 9 is slidably fitted in the inner cavity of the cylinder 8 and separates two secondary compression chambers 6 from both ends of the cylinder cavity along the sliding direction. The inner cavity forms an air intake chamber, and an equal-width cam 1 is arranged in the inner cavity of the middle frame. The rotation direction of the equal-width cam 1 is consistent with the sliding direction of the middle frame body, and the middle frame body is located at the two sides of the two secondary compression chambers. The inner side walls are used to contact with both sides of the equal-width cam when it rotates to form an equal-width cam mechanism. The ...

Abstract

The invention discloses a multi-cylinder type gas compressor. The multi-cylinder type gas compressor comprises a cylinder and is characterized in that a middle frame is arranged at the middle position of an inner cavity of the cylinder in a sliding fit manner and divides the inner cavity of the cylinder into two second-level compression cavities along the two ends in the sliding direction; an equal-width cam is arranged in an inner cavity of the middle frame, and an equal-width cam mechanism is formed; each of the two second-level compression cavities is provided with a second-level cavity air outlet cavity for compression air outflow; each of the two inner side walls of the middle frame is provided with a second-level cavity air inlet valve for air inflow; each of two matched outer side walls, used for being in sliding fit with the inner cavity of the cylinder, of the middle frame is provided with a first-level cavity air inlet for air inflow, and each of the middle portions of the inner walls, used for being in sliding fit with the two matched outer side walls, of the cylinder is provided with a cylinder air inlet. The multi-cylinder type gas compressor has the beneficial effects that the structure is simple, few motion components are arranged, cost is low, work vibration is weak, and the gas compression efficiency is high.

Description

technical field [0001] The invention relates to the field of gas compressors, in particular to a multi-cylinder gas compressor. Background technique [0002] Gas compressor is a kind of power device that converts mechanical energy into gas pressure energy. It is often used for pneumatic tools to provide gas power. Furnace gas, inert gas and other media. In addition, the engine cylinder is also a type of gas compressor. [0003] Existing gas compressors generally adopt a piston structure, that is, the output shaft of the motor drives the piston to perform a reciprocating linear motion through components such as a crankshaft, a connecting rod, a piston pin and a piston head to realize gas compression. [0004] Such existing gas compressors have defects such as many moving components, high cost and large vibration, the piston can only compress the cylinder chamber once in one round trip, and the gas compression efficiency is low. SUMMARY OF THE INVENTION [0005] In view o...
