ROTARY ENGINE l I Gttomeg Patented Feb. 8, 1944 vUNIrED ASTATES PATENT OFFICE Application August s1, 1942, serial No. 456,808
3 claims. -(o1. 'x4-6o) The invention relates-to rotary engines of the wobbler type, wherein a shaft is driven by reciprocating pistons parallel to the shaft and by arms of a wobbler frame mounted on an angular portion of the driven shaft, and has for its object to provide an improved connection between the wobbler frame arms and the reciprocating pistons for hydraulically forming a floating connection, thereby eliminating the use of expansion springs as is now a common practice.
A further object is to provide a self contained fluid pump within each arm connection to the reciprocating pistons, thereby obviating a complicated pumping system through the arms of the wobbler frame.
A further object is to provide transversely movable pistons in the reciprocating pistons, and sleeves carried by each arm axially movable and rockably movable within the transverse pistons and having an apertured partition through which fluid passes to opposite sides of the partition for y n cushioning the floating connections as the Wobbler frame is rotated for driving the driven shaft.
A further object is to provide valve means cooperating with the ports of communication through the partitions so that the cushioning action may be regulated.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without` departing from the spirit of the invention.
In the drawings:
Figure 1 is a vertical longitudinal sectional view through a wobbler type of engine, showing the invention applied thereto.
Figure 2 is a top plan View of one of the reciprocating pistons.
Circumferentially arranged around the driven shaft 2 and in parallel relation thereto are cylnders 5 in which the reciprocating pistons 6 are reciprocated for the wobbling operation.
The connection about to be described is an improvement on Patent No. 2,278,696 and has for its object to eliminate the use of springsfor the floating connection between the wobbler arm 'l and the pistons 6.
Slidably mounted for transverse movement in the transverse openings 8 in the pistons intermediate their length are sleeves 9 which move inwardly and outwardly during the reciprocation of the piston. It has been found desirable to provide a floating connection for transverse movement and to accomplish this result the sleeve 9 is provided with a transverse cylindrical chamber I, in which is rockably and axially movable a sleeve I I having a partition I2 therein. The ends of the chamber I are provided with disc closures I3 having filling plugs I4 therein, and the space vWithin the chamber IB and sleeve II on opposite sides of the partition is filled with a fluid, for instance oil. Each partition I2 is provided with a port I5 extending therethrough, and it will be seen that oil will be forced or pumped from one side of the partition I2 to the other upon axial movement of the sleeve Il, thereby cushioning the action of the floating connection, and at the same time obviating the use of springs for this purpose and substantially providing a self contained pump within each connection. The cushioning action can be regulated by means of valves I5a which cooperate with the ports, hence it will be seen that any amount of cushioning action can be obtained. The ends of the wobbler arms 'I teminate in annular yokes I6, in which Figure 3 is a vertical transverse sectional view through the engine.
Figure 4 is a horizontal sectional view through the pump connection of one of the arms and the transversely movable sleeve taken on line 4 4 of Figure 3.
Referring to the drawings, the numeral I designates the casing of the engine, 2 a driven shaft, which shaft is driven by a wobbler frame 3 mounted on the diagonal crank 4 of the shaft. As the wobbler frame is wobbled, the crank 4 rotates, thereby imparting rotation to the driven shaft 2 forI utilizing the power in any suitable manner.
yokes the sleeves Il are anchored by means of set bolts I'I, therefore it will be seen that a fluid floating connection is provided which is simple in construction, one which may be finely and closely adjusted for regulating the cushioning transverse action and at the same time obviating complicated pumping connections.
' In rotary engines of the wobbler type the arms of the wobbler frame have a lemniscate movement, which is substantially in the form of figure eight, hence it is necessary to provide transverse longitudinal and rotatable connections between the arms and the reciprocating pistons. It has been found that the pump or hydraulic connection set forth performs maximum elficiency Which is not true Where springs are used, and which springs, incident to constant and rapid compression and expansion, loose their tension and often break, and when this occurs it is necessary to disassemble the machine. Applicants hydraulic pump arrangement overcomes the above diiculties and at the same time allows the cushioning action to be Varied.
The invention having been set forth what is claimed as new and useful is:
l. The combination with a wobbler type engine having a wobbler frame, arms carried by said frame, reciprocating pistons disposed in cylinders at angles to rthe arms, said frame being mounted on a diagonal portion of a driven shaft, of floating connections transversely between the pistons and wobbler frame, said floating connections comprising cylindrical chambered members transversely slidable in cylindrical transverse chambers of the pistons, sleeves axially slidable in relation to the axis of the pistons within the cylindrical chambered members, a partition within said sleeve forming spaced chambers entirely within the sleeves and having uid ports therethrough and a cushioning uid within the chamber of the sleeve and adapted to pass through said ports for cushioningr the sleeves as it is reciprocated said arms carried by the wobbler frame being connected to the reciprocating sleeves.
2. .An arm connection between a wobbler frame arm and a reciprocating piston of a wobbler type rotary engine, said connection comprising, a transversely movable chambered member slidably mounted in the piston, a reciprocating sleeve transversely positioned in the chambered member, a partition in said sleeve for forming fluid chambers on opposite sides thereof, fluid in said chambers and adapted to be forced through a port in the partition as the arm describes a 1emniscate movement, said arm being connected to said reciprocating sleeve.
3. A device as set forth in claim 2 including means carried by the partition for regulating the ovv ofuid through the port in the partition.
