CoN'rRoLLlNG 2 SHEETS-SHEET 2 cally Within the distributing` slide 4. Slide 5 is journaled in the distributing slide 4 by means ot' ball bearings 28, and the distributing slide 4 is, .in turn, journaled in the casing 1 by rmeans of ball bearings 29. The controlling slide 5 is divided by means ot a partition 31 into a suction chamber 32 coinniunicating at one end ot the slide With the space 2l, and a pressure chamber 33 coinmunicating at the opposite end ot the slide With annular passages F arranged in the end Wall 34, the rsaid passages comnnmicafting-With a pipe socket 36 to which the coni mon outer pressure piping` 30 is connected. @n either side ot the partition 31 the controlling slide is provided with recesses in the cylindrical Wall which recesses are so arranged between guiding edges 37, B3 and 39, respectively, Fig. 2, that the openings 23, 24, 25, 26, 27 in the distributingl slide will be successively covered by the edge 37 and uncovered bythe edge 89 on rotating the slide in the direction ot' thearrow 41, whereby the corresponding pressure passages 18 will be successively cut otl trom the pressure chamber 33 in the slide and instead brought in communication with the suction chamber 32. On rotating the controlliiiig slide 5 in the direction ot the ari-or,Y l42, the shifting is taking place in the opposite order at the guiding edges'S and 40. The openings 23 mayf-be made common ttor a plurality of pressure passages 18 in the distributing` slide, so that the shitting oit' these passages is taking place in groups comprising two or more passages. In the example shown, each ot the openings 24 and 26 is common for two passages 1S, ivhiie the opening 25 is in communication with only one passage 18.
The adjustment ot the controlling slide 5 with respect to the distributing slide 4 is effected by means of a systemv ot gear Wheels 43, 44, 45, 46, 47 (Figs. 1 and 4)'engaging with one another, the said Wheels forming at the same time a gearing ttor the transmission ot motion troni shaft 11 to the slides 4, 5. The 'gear Wheel 43 is secured to the end ot the shaft 11, Whereas the gear Wheels 44 and 45 are mounted en studs G0 and 61 rigidly attached in the parL ti-tion 13', and the gear Wheels 46 and 4'? on studs G2 and 63 attached to a ring48 which is rotatab'y mounted on a cylindrical. rll'ange 49 projecting fromthe said partition. hiforeover, lgear 45 engages with a toothed rim arranged on apart 51 which is rigidly Connected with the distributing slide 4. and gear 47,'engages with a toothed rim l2 arranged on a part I53 which is rigidly connected with the controlling slide 5. " lh'e gear Wheels 44, 45, 46, 47 being of the saine size, the two l'slides '4 and `5 Wili 'be driven ait .the same speed from shaft 11, it beingl assumed that "the .ri-ng V4S is. secured in a Lelio/ies ly. The ring 4S is provided with a toothed rim engaging With a toothed mounted for reciprocation in the cas g 1 ot the generator, Fig. 4, the said rech being connected, with an operating lever 3o which may be secured in known manner in 'va ous positions on a slotted bar se nient 5?. By the `adjustment oi' the operating lever 56, the gear vWheels 46. 47 evidently m be adjusted and secured in ditferent posi-- tions during the operation ot the generator, the Controlling slide being then brought along and zidjuste'l in co 1respending positions relativel kto the distributing slide.
The mode ot operation is as follows: lVhen the distriluiting slide 4 holds th position shown in Fig. 2, the piston oit he uppermost cylinder 2 is at the end oi its compression stroke. lt is assumed that the generator rotates in the direction indicated by the arrow 41, igs.r 2 and 3, the slides 4, 5 then rotating in the direction ot the arronY 42.' In the said position et the distributing slide, the passager 14 is shut o?,F entirely. @n the piston reversing` its direction and commencing its suction stroke, communication is being established by grecs with the suction pz sage 17, and when the piston passes the centre position ot its suction stroke, the opening 19 registers with the opening 15. Thus, the connection between the said two pressure passages is complete, when the piston has its greatest l n u, speed. @n the pist-on reachniig its mnei1- most position. the passage 14 is again shut voit entirely, and `when the piston on reversing its direction commences its pressure stroke, the passage 14 is again brought in communication with rthe nent pressure pas sage 18 in the distributing slide. The control ot the remaining cylinders is effected in the same manner, but With a time interval. corresponding -to the angular displacement ot the cylinders.
Assuming that the controllingl slide has the relative position disclosed in Fig. 2, the Whole quantity of liquid pumped 'by all ot the cylinders, will be itorced through the openings 2S, 24, 25, 26, 27 into the pressure chamber 33 in the controlling slide and thence into the outer pressure piping. It the controlling slide 5 is adjusted so that the opening 23 is shut ott trom the pressure chamber 83 and brought in communication With the suction chamber 32, tvvo cylinders will evidently be shut otl' from the pressure chamber 33 .during the pressure stroke, that each cylinder will be sluit oli' f Virc-ni the said prl e chamber consecutive pressure strokes7 ru'ieated once lor every revoluc controlling slide The result that the total quantity oi out- ,i a quantita7 idling *o the quai v ci liquid supinders. .ln like manner7 the ot liquid may be 'further a continued rotation ol the slide slide 5 has been rotated so that openings Q2, 2e, 2T have ofi Ytrofl :he pressure chamber nstead put in communication with the suction chamber 32, the generator obviously does not supply any liquid to the outer pressure pip but the ivhole quantity oit liquid pumped is circulating through the generator.
llben the controlling slide 5 is adjusted, the openings 253, 24E-Y, 26 27 respectively uill b shui' oil fmtirely.x (hiring a short time interval, t'rom the pressure chamber 3?) as well as from the suction chamber 32. ln order to provide ttor the requisite outlet Vtor ot this is going active liquid is reduced of the liquid during this moment, there arel arranged spring-actuated 'valves 58 at the ends oi the passages la? Fig. l the said valves establishing communieation. at a pressure which is above the norma-h with a space 39 which is preferably connected with the outer pressure pipinfr.
l the generator operates as a motor, reversing is eliected by rotating the distribti slide l in 'the one or the otlier direv-tic@ so that the respective suction pasn'ill assume the positions ot the ad- Icent i-)ressure passages.
