Embodiment 1
[0027] Example 1: see Figure 1-2 :
[0028] The multi-cylinder translational compression device includes a motor 10, a main shaft 11, a crankshaft 12, a piston, a chute composed of upper and lower cover plates 40, 41, and a cylinder body 30. A group of pistons 21, 22 are connected to the crankshaft 12 driven by the motor main shaft 11. Of course, two or more sets of pistons can also be set on the crankshaft 12. When multiple sets of pistons are set, the axis of each set of pistons should be arranged to cross and evenly distribute on the axis of the main shaft. direction reciprocating movement, the cylinder 30 and the pistons 21 and 22 reciprocate in the left and right directions under the restriction of the upper and lower cover plates 40 and 41, and the upper and lower cover plates 40 and 41 are respectively provided with inlet and exhaust passages 401 and 402 , 411, 412, inlet and exhaust valves are respectively arranged in the inlet and outlet channels 401, 402, 411, 412,...
Embodiment 2
[0030] Example 2: see image 3 and Figure 1-2 :
[0031] The basic structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the above-mentioned cylinder body 30 can also be partially or completely closed, that is, the upper and lower openings of the cylinder body 30 are respectively fixed with fully closed upper and lower openings. Cylinder cover 31,32, at this moment, cylinder body 30, piston 21,22 and upper and lower cylinder cover 31,32 form two compression cavities 81 and 82, on upper and lower cylinder cover 31,32 and upper and lower cover plate 40,41 enter , The corresponding positions of the exhaust passages 401, 402, 411, 412 are provided with intake and exhaust openings, and the intake and exhaust openings of the upper and lower cylinder heads 31, 32 and the intake and exhaust passages 401, 402, 411, and 412 are respectively provided with sealing devices 52 for the intake and exhaust passages.
[0032] The motor 10 works, ...
Embodiment 3
[0033] Embodiment 3: see Figure 4 and Figure 1-2 :
[0034] The basic structure of this embodiment is basically the same as that of Embodiment 1, the difference being that left and right compression chambers 83, 84 are respectively provided on the left and right sides of the cylinder 30 other than the above-mentioned cylinder 30, and the outside of the cylinder 30 The left and right sides of the left and right sides are made into the structure of pistons, and the left and right cover plates 42, 43 of the left and right compression chambers 83, 84 are also respectively provided with inlet and outlet passages 421, 422, 431, 432, and in the inlet and outlet passages 421, Intake and exhaust valves are respectively arranged in 422, 431, 432, and intake and exhaust joints are respectively arranged at the outlets of the intake and exhaust passages 421, 422, 431, 432 on the above-mentioned left and right cover plates. The structure can also be transformed into a compressor structu...
