The air off-tiike pipe 1.3 and the gas oli-take pipe 12y connect together through the lead 13X with the pipe )3F whose ends communicate with the right und left hond ends re spot-.tively of the pumping cylinder 2 sind. t
e sind f pipe 13y is provided i\ ith check valves 13-13 and cut-oil' vulves 13"--13b es clearly shown in Ngs. 1 nud Z of the drawings.
The cylinder 1, at points intermediate the center and ends, has two set-s of escape ports 17 that open into nn annular jacketl 17" which .discharges into an'iii'i'ttike 17h to the atmosphere.
Operation: Assuming the/parts to be. in the osition shown in Fig. 1 a. coin ressed working` charge in the left hand en of the working cylinder justabout to be exploded, the pipe 7 filled with air. the right hond end of the working cylinde:- having the burned mixtiireexhausted and just about filled with new working agent, the pi ie S rind the remaining: spiice in the left and er.-d'ol' the pumping cylinder being: tillcd with working: :igt-ntnnd valve Y being in the iosition shown; iis the charge fit the left Imm end of the working; cylinder is exploded und Ithe pistons moved in the direction indicidedliv the :irri-iw, the valve 7'l will be. held closed,- diie to the pressure of the exploded clmi'g'e in the left hand end of the cylinder. the vola-'eab at the left hand end of the working cvlinder will be closed vdue to the pressure in t ie pipe 7 which increases as the pompini! pis-ion moves in the direction of the iii-row to com press the working agent in the right hand end of the pumping cylinder. Now -sis the pistons begin their movement in the direction of the arrows in Fig. 1, the. working piston X will close the right hand set of exhaust ports 17, and compress the chiirge of 'working agent within the right hand end of theworlr-l ing cylinder, it being undeistood, that n.5.A
'l0-10h as the pipe 1Uh is in communication einem dn compression in the right hand end o@ the working cylinder begins, the valve 8"s will be heldv closed by the pressure y'if the working agent in the. right hrendv end of the working i with the pipe 1l through the' portal 15b-15C.
. The beginning of the movement of the pistons from left to right is a quick one and hy the time piston Y has drawn the. Working agentwhiclr was formerly in pipe 8 out of the saine and drawn suliicient air into the pipe 8 to. ll the same, the suction created by the air passing through pipe 1l into pipe l0 causes a partial vacuum in the. chamber 14 Ywhich shifts the valve member 15 to the poias sition shown in Fig. 2. After thevalve been shifted to the position shown in Fig. 2, which occurs just as soon as the pipe 8 has become filled with air, then the piston Y can no longer draw air into the pipe 8 through t-lie pipe lil-10b as the ipe 10" is cut ott from the air pi e 11. 'l.` e pipe S remains full of'airduring the `rest of the suction stroke ofthe pump, since the suction created by auch stroke draws air and gas through pipes 11, 13, 12 and'12y into' the left hand end of the pumping cylinder, it being understood that at this time pipes l2 and l2 and 1 1 and 13 respectively, are in communication with eachother. As the )ist-ons reach the limit of their stroke in the iiect-ion indicated by the arrows in Figs. .1 and 2, the
workinglagent in the right hand end ol the pump pistons will lia-ve been compressed to its full extent. while an uncompressed charge of working agent will have been drawn intol the'left hand end of the pump cylinder. At t-hc saine time the working avent in the right hand end of the working cfliiidei' will have. been compressed while the exploded mixture iii the left hand end of the cylinder will have moved the piston in the direction indicated by the arrow and spent its force.
Lpistons reach tlie'limit of their stroknin the direction-of the arrow` the left hand series of I exhaust. ports 17 of the workingy cylinder will be uncovered, thus allowing' the exploded charge to pass out into the exhaust i'ecci-ver and from thence to atmosphcre,and as soon as theexhaust ports l? are open at the left is at practically atmospheric pressure and the compressed air in pipe 7 and4 compressed working agent charge in rightl hand end of the pumping cylinder. As valve 7 opens e the compressed charge in the right haio end of the pumping cylinder will force the' air out of the pipe 7 into the left hand end of the working cylinder which air of the pipe 7, .iii turn, forces out the exploded mixture from the left hand' end of the working cylinder to atmosphere; the air from the pipe 7 being then forced out of theleft hand end of the 'working cylinder by the compressed charge of new Working agent from the right hand end of the pumpinpr cylinder, it being understood that the pistons X and Y do not start on their return stroke in adiiection opposite to the arrows iii Figs. 1 and 2and cover up the left hand seriesof'poits 17 of the working cylinder, until the compressed chai'ffe of working agent in the right hand end (il the pumping cylinder has forced the air out of pi e 7 into the left hand end of the working cy inder and out of said end of the working cylinder into the exhaustreceiver. As soon as this is done and thc left. hand end of the working cylinder has become filled with a,
new charge, the pistons-X and Y begin their .movement from right to left in the direction opposite to the arrows in Figs. l and 2 t0 compress the chargeof working agent intopage of both pistons when no movement` At this instant, the vacuum in .the chamber 14 n released and.
`thereof takes place.
