Embodiment
Referring to figs. 1 through Fig. 4, the utility model two juxtaposed cylinders is described further without oily piston two stage compressor embodiment.
A kind of two juxtaposed cylinders is without oily piston two stage compressor, comprise pump machine, described pump machine comprises bent axle 13 casees 1, belt pulley 2, bent axle 13, fork 14 is provided with in described bent axle 13 casees 1, described belt pulley 2 is fixed on bent axle 13, bent axle is provided with piston cylinder 3 13 casees 1, and fork 14 one end is enclosed within the bent neck place of bent axle 13, and the other end is connected with without oily piston 15.Because belt pulley 2 is by connecting the runner of motor outside belt, the work that the rotating band dynamic crankshaft that such motor is moved by belt is 13 casees 1.
Two parallel piston cavity are provided with in described piston cylinder 3, be respectively first stage piston chamber 31, second piston chamber 32, the aperture in described first stage piston chamber 31 is greater than second piston chamber 32, be equipped with matching without oily piston 15 inside first stage piston chamber 31 and second piston chamber 32, be connected with fork 14 without oily piston 15.Bent axle 13 has two bent necks above, and each bent neck connects a fork 14, is then driven by the motion of fork 14 and moves in piston cavity without oily piston 15, guarantee the compression of gas.The aperture in first stage piston chamber 31 is larger, significantly air compressing can be come in, and aperture, second piston chamber 32 is smaller, because overall volume has just diminished after air compresses in first stage piston chamber 31, therefore the air of same amount to enter into from first stage piston chamber 31 can be stable in less second piston chamber 32, aperture carried out secondary compression, make the pressure that air pressure reaches enough.
Two piston cavity be set up in parallel all are opened in inside a piston cylinder 3, effectively reduce volume, and the piston cavity that two bores are different, can guarantee the stable of both implements spatial scalable compression.
