Mounted upon the periphery @if 4he mier 8 and epiiued thereto by means of a. key 11 is a ringheped element 12 corresponding in iii a, series oeylindrical passages 13 which ,cmxesjpend in size and number with 'the seid openings 10. 10. in ihe pevipherai extension 9, the seid ring: i2 heilig so disposed upon die rotor 8 that the said openings i() and 13 are in idignmenhihe common mee of zhe npposieiy dispnsed pai-rs ef openings heing lismilei ce ,the :mie ei5 the mier :md 0i.' the shaft 7.

Extending inwardly from the interior of the casing 1 is en annular lug 15, said lug being; substzmtialiy veentraiiy disposed between the inner faeee of A-ihe port heads 2 und A, port 16 is *formed iu the top of the casing; :uid the Seid lng 15 extends mound the casing from/the edges 0f the Said port 16, as moet dearly shown in Fig. 1 6. To the use i said lug l is adapted to bc secured by means of bolts 17, a cani ring 18, the said cam ring being of wave-like formation, as most clearly illustrated-in Figs. 3 and 17. The cam ring 18 is in the form o a complete ring, and a section 19 thereoic underlyingthe said open ing 16 is detachable from the main section and may be removed therefrom. 4
Established Within the cylindrical openings 10 and 13, are pistons 20, said pistons having suitably secured thereto rollers 21 which are adapted to engage the opposite side faces of the cani 18 in the manner clearly illustrated in Figs. 1 and` 2. ln the present instance, the pistons 2O which occupy the respective sets of aligned' cylinders 10-13 are united by au arm 22, and the said rollers 21 are mounted upon spindles 23 which extend between this arm and an inward projection on cach of the said pistons. f
It will be clear frein the foregoing description that as the rotor 8 revolves the said respective sets of pistons 20, 20, will reciprocate laterally in a direction parallelling thc axis of the shaft 7 in accordance with. the formation of the cam 18, the roller 2l ot one of said united pairs of pistons occupying a recess in said cani when the opposite roller 1n the said port heads 2 and 3 While similar axially rests against an opposite extension.
s previously stated, the machine is adapted to be employed either as a motor or as a pump, and suitable ports are provided for the admission and exhaust to and from the outer end of the cylindrical openings 10 and 13V ot an actuating Huid.
As most clearly shown in Fig. 2, the port heads 2 and 3 are each provided with a pair ot annular grooves in the peripheries thereof, the said grooves ot the port head 2 being* indicated b7 the reference numerals 26 and 27, and the grooves of the port head 3 being,` indicated by the reference numerals 28 and 29,' and these groovesare adapted to communicate by means of suitable ports with chambers or manifolds 30,131, 32 and 33, formed in the said casing l.
-tion between the grooves 26: and 22' and the outerends of the cylindrical openings 10, disposed ports 3G and 37 establish communication 'respectively bet-'Wee'n the grooves 28 and 2S) and the outer ends of the cylindrical openings 13'. said ports 34, 35, 36 and 37, are so disposed in their respectiveport heads that the ports 34 in the port head 2 lie directly opposite to the ports 36 of the port head 3, while the ports 35 of the port head 2 lio ,directly opposite the ports 37 of the port head 3, the said ports 34 and 35, as most clearly shown in Fig. 7, being arranged alternately in a circle, the center of which is the center line The and 3'?, at the saine ot' the shaft 7, the ports 36 and similarly alternately mounted head 3.
ltv will be seen from the above that when one of the cylindrical openings l0 registers with one et' the ports 34, the said cylindrical opening 13 will register with one nii' the ports 36 of the port head 3, While when the said cylindrical opening4 10 registers with one of the ports 35, the opposite cylindrical opening 13 will register with one of thc ports 37. In the present instance, the. manifolds 30 and 32 are, we will suppose, intake manifolds, `While vthe manifolds 31 and 33 are exhaustn'1anitolds,`and the arrangement is such that `While the grooves 27 and 2S) communicate through ports Llt), fill, with tho manifolds 30 and 32,. the grooves 26 and 23 communicate by moans oi. ports 41, ell., with the manifolds 31 and lt will thus he seen that when one end of the tandem cylinder formed hv each pair of yoppositely disposed cylinder openings 10 and 13 is in communication with the exhaust` the opposite en'd will be in communication with the intake, manifolds.
Extending inwardly in the present instance froin the outer tace of the port head 3 are ports 42 and 4:3 constituting,` respectively exhaust and intake ports for an actuating!1 yfluid. The said port 413 c'oinu'uuiicul'cs with a centrally disposed annular chamber ll, from which extend passages l5... into the bottoni of the said groove' 2) whereby au actuating fluid entering through the port '.43 is distributed thi'ouajh thc said groove 2S) lo ports 37 of the port head il. and to the iutake manifolds 3l? und 3"). from whence it, passes through the .ports 4a" to the groove 27 of the port head 2, said :u tuutine; fluid then passing through the port," 3l iulo the cylinder openings 10.
From thel port 42 l extend passages 4d, 46, into the base of the groove l, u' roby o passage is afforded lor the actuating,r fluid which is exhausted from the cylinder oponings 13 through the ports 36, and also for the actuating fluid which is exhausted from the cylinder openings 10 'thr-'ugh the ports 35 into the grooves 26, these latter grooves comi'nunicating with the said manifolds 3l and 33, as previously stated, through the port 41 and also with the `groove 28.
The operation of the device is as follows: An actuating iiuid, introduced in the present instance through the port 43, isiled in the manner previously explained to the'ports 34 time the'ports 35 and 36 being opened to the exhaust alsogas previously described. .Since the ports'Bll and 36 are oppositely disposed, as also are the ports 35 and 37, it will he apparent that as the rotor 8 revolves, the opposite ends of the tandem cylinders formed by each pair of oppostely disposed cylindrical openings 37 lfeinp; in the port IUE lill
