This invention appertains to new and useful improvements in engines and more particularly to an engine or motor adapted to be operated by compressed fluid.

The principal object of the present invention is to provide a fluid operated engine wherein the parts are positive acting and. not susceptible to the ready development of defects.

Another important object of the invention is to provide a compressed fluid operated engine, the rotation of which can be reversed quickly and efliciently.

Still another important object of the invention is to provide an engine of the character stated wherein the parts are of simple construction and assembled in an accessible and practical manner.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the engine.

Figure 2 is a vertical sectional view through the engine taken on the line 2--2 of Figure 1.

Figure 3 is a side elevational view of the engine with one side wall removed and the pipes on the approach side in section.

Figure 4 is a fragmentary detailed sectional view taken on the line 4-4 of Figure 2.

Figure 5 is an inside elevational view of one side wall of the stator.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the stator is generally referred to by numeral 5 and the rotor by numeral t. The stator consists of the cylindrical wall structure l and the two end wall structures 8--9, one of which is preferably removable to permit access to the interior of the stator.

At the proper intervals around the circumference of the cylinder "i are outstanding cases it in each of which is the slidable abutment ll operating between anti-friction rollers l2. A spring It in each of the cases it serves to urge the corresponding abutment ii toward the rotor 8, so that it will ride against the periphery of the rotor and into the pocket it. The ends of the pocket are sloped as at it to facilitate entrance and exit of the abutment with respect to the pocket.

Each side of the engine is provided with a supply pipe and an exhaust pipe. On one side of the engine is the compressed fluid supply pipe l6 which is of annular formation as is the corresponding exhaust pipe ll. On the other side of the engine is the supply pipe i8 and the exhaust pipe l9. Extending to the pipe i6 is the supply pipe 58 and from the pipe ll extends the pipe 19' and in these pipes are the valves 2t2i, respectively, connected by the link 22 and operated by the handle 23.

From the pipes l8i9 extend the pipes 24-25 in which are the valves 262i connected by the link 28 and operated by the handle 29 in unison.

As is shown in Figure 3, the pipe I6 is provided with branch extensions 3b which extend into the stator l and deliver compressed fluid into the pocket on the left sides of the abutments H. The rotor t is provided with ports it, one for each of the pockets i4 and with these pockets are registerable the grooves 32 in the side wall 9 from which grooveways extend the branch pipes 33 to the exhaust pipe ll. Thus it can be seen, that while compressed fluid is being supplied to the left side of the top abutment in Figure 3 so that the rotor 6 is being moved in the direction of the arrow, fluid in the pocket at the right side of the abutment H is escaping by way of the adjacent port 3!, groove 32 and pipe ll.

When a reverse rotation of the engine is desired, compressed fluid is supplied from the pipe 18 by way of the branch pipes 3 3, which result in movement of the rotor in the opposite direction while air behind the abutment is escaping by way of the ports 35 and stator grooves 36 to the pipe 19. This reversing operation is obtained by closing the first set of valves shown in Figure l and opening the second set, thus changing the delivery of compressed fluid from one side of the abutment to the opposite side.

Numeral 3! denotes the drive shaft which is equipped with the gear 33 while interposed between the gear and the ring gear 39 on the inside of the rotor ii are the planetary gears til.

As can be seen in Figures 4 and 5, the inner sides of the walls 9-10 are provided each with an annular arrangement of pockets 5!] with which the ducts 5i extending downwardly and laterally from the pockets l5 register. Thus the fluid pressure can be supplementarily used to afford a turbine effect between the rotor and stator.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

in a given direction, said rotor having curved passages therein, one for each pocket, each passage having one end in communication with the rear end of a pocket and its other end opening out through a side part of the rotor and the adjacent side of the stator having a plurality of grooves therein for communicating with the passages duringa portion of the rotary movement of the rotor and exhaust means connected with said grooves.
