Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, the invention will be further described, referring to Fig. 2-Fig. 4：
The double-barrel air cylinder feeder of butter machine, including pump housing seat 25, the cylinder 19 installed in the upside of pump housing seat 5, for gas
The piston upper and lower cavity 41 of cylinder 19, the reversal valve 31 of 42 distributions, the cylinder 19 includes being arranged in inner core 21 and outer tube 20, inner core 21
There is the piston 11 being connected with piston rod 13, between the external cylindrical surface of inner core 21 and the inner cylinder face of outer tube 20 the first ventilation is provided with
Passage 12, the air supply opening 16 of reversal valve 31 or air vent are connected by the first venting channels 12 with piston upper chamber 41, reversal valve 31
Air vent or air supply opening 16 connected with piston cavity of resorption 42 by inner passage 14.
The upper surface of above-mentioned outer tube 20 has been centrally located suspension ring 18.
The top of above-mentioned suspension ring 18 is annular ring, and the bottom of annular ring has extended downwardly screw rod connecting portion, and suspension ring 18 are placed in the middle
It is screwed onto the upper surface of cylinder 49.
Above-mentioned suspension ring 18 are annular ring, and the bottom of annular ring is welded between two parties the upper surface of cylinder 19.
Above-mentioned inner core 21 and outer tube 20 are split-type structural, the upper opening of inner core 21, the upper surface of inner core 21 and outer tube
The second venting channels 10 connected with the first venting channels 12 and piston upper chamber 41 are provided between the lower surface of 20 upper walls, so as to
The gas sent in reversal valve 31 sequentially passes through the first venting channels 12, the second venting channels 10 and connects with piston upper chamber 41.
The top of said pump housing 25 is tightly connected respectively with the lower surface of inner core 21 and outer tube 20, and inlet suction port 23 stretches out
Outer tube 20 is outer and is connected with pressure regulator valve 22.
The work of the present invention：Source of the gas is connected, switch is opened, pressure-air can be by air inlet connecting after the pressure regulation of pressure regulator valve 22
23 enter, then the first airspace 12, second between the inner core 21 and outer tube 20 of the distribution tailing edge cylinder 19 of Jing reversal valves 31
Venting channels 10 enter piston upper chamber 41 and (assume that the now distribution of reversal valve 31 causes the air inlet of piston upper chamber 41, the row of piston cavity of resorption 42
The position of gas), promote piston 11 and piston rod 13 to move down, the pulling sleeve on piston rod 13 drives while moving down with piston rod matches somebody with somebody
Gas slide block is moved down, and when being displaced downwardly to lower limit position, that is, realizes the aerofluxuss of piston upper chamber 41, the exchange of the air inlet of piston cavity of resorption 42, according to
