As the air of air compression plant, shown is example with the pressurized gas only, is not limited to air (for example, also can be nitrogen, oxygen, argon gas) clearly.
Below, utilize accompanying drawing to describe embodiments of the present invention in detail, but shown be representational example, as long as be no more than its main idea, the present invention is not limited to following embodiment.That is, technical scope of the present invention is not subjected to any restriction in the following example.
Embodiment
Fig. 4 is the stereogram as the cylinder part 40 of the constituting component of the gas piston compression set 100 of one embodiment of the present of invention.As shown in Figure 4, cylinder part 40 is made of the 1st cylinder part 41 and the 2nd cylinder part 42 these two cylinder parts, and the 1st cylinder part 41 and the 2nd cylinder part 42 link up by snorkel 50.
Fig. 6～Fig. 8 is the sectional view of above-mentioned gas piston compression set 100, and in this Fig. 1 and Fig. 2, for the easy to understand invention, the part of cylinder part 40 is a sectional drawing.
It is the most forward 180 degree on counterclockwise horizontal line that Fig. 6～crank mechanism 10 shown in Figure 8 is assumed to respect to the crank rotating center, and retreating most is 360 degree.
At this moment the 1st crank mechanism 10a is that radius 7.1mm-180 degree, the 2nd crank mechanism 10b are that radius 4.9mm-165 degree, the 3rd crank mechanism 10c are that radius 4.9mm-345 degree, the 4th crank mechanism 10d are radius 7.1mm-360 degree, and crank mechanism is in balance.
In detail, make the phase difference of the 1st crank mechanism 10a and the 4th crank mechanism 10d and the phase difference of the 2nd crank mechanism 10b and the 3rd crank mechanism 10c differ 180 degree, and, also be provided with phase difference (that is, being arranged between the piston element in the same cylinder part) between the 1st crank mechanism 10a and the 2nd crank mechanism 10b.
Rotatablely moving of piston shaft parts 15 successfully can be transformed to the round slip of piston element.And, the spin balancing of piston shaft parts 15 and rotational speed are improved.These all are the principal elements that is improved for the compression efficiency that makes gas.
Crank mechanism 10a and crank-connecting rod 11, piston shaft parts the 15, the 2nd piston 21, crank mechanism 10b and crank-connecting rod 12, piston shaft parts the 16, the 1st piston 22, crank mechanism 10c and crank-connecting rod 13, piston shaft parts the 17, the 2nd piston 23, crank mechanism 10d and crank-connecting rod 14, piston shaft parts the 18, the 1st piston 24 link up and obtain the balance with respect to the back and forth movement that rotatablely moves respectively.
The piston shaft parts 15,17 that are attached at respectively on the 2nd piston 21,23 are concentrated in one-sided by being penetrated into the through hole that the 1st piston 22,24 is provided with respectively.Therefore, only with a rotary system 2 pistons that are configured in each cylinder part are come and gone slides.That is, can make simple in structure.
Be set up in parallel two cylinder parts and make air flue b and pressure valve integrated body 20 by folding and unfolding the 1st cylinder part 41 of the 2nd piston 21 and the 1st piston 22 and folding and unfolding the 2nd cylinder part 42 of the 2nd piston 23 and the 1st piston 24 constitute.
In case crank mechanism 10 is rotated counterclockwise, the 2nd piston the 21, the 1st piston 22 and the 2nd piston the 23, the 1st piston 24 in each cylinder with each crank radius back and forth movement.At this moment just obtain being clipped in the cylinder volume volume post (space) 31,33,35 among the 2nd piston 21 and the 1st piston 22 and carried out the compression movement of air.In addition, in another cylinder volume, also obtain being clipped in the volume post 30,32,34 among the 2nd piston 23 and the 1st piston 24 and carry out the compression movement of air.Just obtained having effectively utilized the compression stroke of the volume post 30,31,32,33,34 that obtains these both sides.
Crank mechanism 10a is rotated counterclockwise 0～180 degree, and because of the rotation of the crank mechanism that is accompanied by, air just is inhaled into the volume post 33,34 from air-breathing relief opening 26.
Then, crank mechanism 10a Rotate 180～360 degree, because of the rotation of the crank mechanism that is accompanied by, the air in the volume post 33,34 just is compressed in the volume post 35 and is closed.
Crank mechanism 10a is rotated counterclockwise 0～180 degree for the 2nd time, and because of the rotation of the crank mechanism that is accompanied by, the pressurized air of volume post 35 is compressed once more and is discharged from from air-breathing relief opening 27, and at this moment crank radius is 7.1mm-4.9mm=2.2mm.
The trip carries out alternately by the total cylinder of both sides.That is, air is sucked volume post 30,31 from air-breathing relief opening 25, again it is compressed to volume post 32 and sealing the opposing party.Then, compress once more and discharge from air-breathing relief opening 28.
Shown in Figure 3 is the flow process of gas, as shown in Figure 3, because the gas that sucks the gas of volume post 31 and suck in the volume post 30 diminishes volume post 31 and volume post 30 (gap between the bottom of piston 22,23 and the pairing cylinder part 41,42) by piston 22,23 towards the slip of the end wall of each cylinder part 41,42, and moves in volume post 32.
That is, because the gas in gas in the volume post 31 and the volume post 30 is mobile in volume post 32, can be in this stage with about 2 times of gas compression.
Here, owing to make length (that is, the crankweb) difference of above-mentioned the 1st crank mechanism 10a and the 2nd crank mechanism 10b, between the 1st piston 22 that slides in same direction and the 2nd piston 21 phase difference being set.Promptly, distance when can leaving at the head of the head of the 1st piston 22 and the 2nd piston 21 and near when distance between a difference is set, thereby can follow the slip of the 1st piston 22 and the 2nd piston 21 will pass in the snorkel and the gases that are sent in the volume post 32 further compress.
