Detailed description of the invention

In the accompanying drawings, an air compressor has been described for the purpose of illustrating the principles of the present invention. It should be understood, however, that various features of the present invention, in particular the inflow and outflow of the reciprocating piston and the transition from reciprocating to rotational and vice versa, have their usefulness and are not compatible with air compressors, for example, Pumps, steam engines, internal combustion engines, etc. may be used successfully.

The compressor of the present invention, shown generally as 10 with reference to FIGS. 1 to 5, has a cylindrical housing with a bore 14 defining the interior to the housing 13 and blocked by an end wall 16. And a stator 12 made of 13). In this embodiment the end walls 16 are provided with four ports 18, respectively, which are arranged equiangularly and annularly around the end wall 16. As an example of these four ports each port is annularly disposed at 90 ° with respect to the adjacent port 18. It should be understood that the four port arrangement in one of the end walls 16 is axially rotated relative to the arrangement of four ports of the opposite end wall to prevent direct communication through the interior of the housing. The lower part of the cylindrical housing 13 is provided with an ear 22 through which a bolt 24 extends to secure the housing 13 to a corresponding threaded passageway (not shown) in the base member 20. The same is adapted to be secured to the base member by being provided. The end wall 16 is also secured to the cylindrical housing 13 by means of bolts (not shown).

The rotary assembly, shown generally at 26, consists of a central shaft 28 extending axially through the bore 14 of the cylindrical housing 13, each bearing assembly at the center of the end walls 16. Supported by the rotatable 30. The cooling disc 32 is secured to the shaft 28 for rotation with it and is arranged on the shaft 28 in two groups of six disks each. In addition, each group of disks 32 is spaced apart to provide airflow therebetween. The disc 32 is provided with four holes 34 each and spaced apart by 90 °, and the end wall 16 from the center of the disc for intermittent arrangement with the port 18 when the disc and shaft rotate. Located radially. The hole 34 is arranged parallel to the axis of the shaft 28 to use and secure the end portion of the cylinder element 36. As described the four cylinder elements 36 are arranged parallel to each other and to the axis of rotation of the shaft. Appropriate packing collars 38 are provided, with each cylinder element 36 being open and ended and having a coupling that slides with the inner surface of the end wall 16 of the stator 12 so that the fluid tightly engages it. At the opposite end. Suitable packing materials are well known in the art and do not form themselves in part of the present invention. Reciprocating piston 40 with a piston head 42 on each end and a reciprocating piston with one or more piston rings 44 for tight and slippery sealing of fluid with the inner wall surface of the cylinder element 36 40 is disposed to slide on each cylinder element. Each piston 40 is provided with a piston pin 46 which protrudes through a slot 48 which is disposed radially towards the center of the respective pistons and each extends in an axis provided in the side wall of the cylinder element 36. do. An extended end of the piston pin 46 is provided with a cam difference 50 which is arranged to receive a sinusoidal cam track 52 formed in the inner wall of the cylindrical housing 13 of the stator 12. In order to reduce friction, the cam bogie 50 is journalized to rotate around the piston pin 46 for use as a roller in the cam track 52. The design and placement of cam bogie 50 in cam track 52 is well known in rotary engine and pump structures and does not itself form part of the present invention.

In operation, power is applied to the shaft 28 by means such as an electric motor to cause rotation of the rotatable assembly in the stator 12. The rotary assembly 26 rotates so that when the rotary assembly 26 rotates with respect to the stator 12, the pistons in their respective cylinder elements due to the action of the cam follower 50 on the edge of the cam track 52. Allow 40 to reciprocate. Each piston head 42 is operated in a two-stroke cycle that draws air into the cylinder element and compresses the air during the compression stroke. During the suction stroke, the pressure is reduced in the area defined by the piston head 42, the side walls of the cylinder element 36 and the end wall 36. When the cylinder element 36 moves around the end wall 16 and is arranged with the port 18, it is sucked into the defined area and the cylinder element 36 is out of alignment with the port 18, and the piston head 42 is The compression stroke begins when the piston head 42 begins to move toward the end wall to reduce the volume of the defined space but to compress the air therein. When the compression stroke is completed, the piston 40 reaches the upper dead center and the maximum compression in the piston head 42 is reached. Compressed air, when moved to align with the port 18 next to the cylinder element 36, directs the compressed air through the port 18 in the cylinder element 36 to a storage tank or user's device (not shown). To the manifold and line (not shown). It should be understood that when one head 42 of the piston 40 is in the compression cycle, the piston 42 at the opposite end is in the suction stroke. In effect, therefore, each piston 40 is operated as two pistons. In the illustrated embodiment each piston head 42 completes two suction and compression cycles while the rotary assembly is fully rotated 360 °.

Compression of air in the cylinder element 36 and reciprocation of the piston in the cylinder element generate heat in the pump. The spaced apart disk 32 supported by the shaft 28 conducts heat generated in the cylinder element to radiate heat into the interior of the cylindrical housing. Accordingly, the disk 32 is preferably formed of a thermally conductive material such as aluminum. The cylindrical housing 13 is provided with a recess 54, in which a discharge hole 56 for circulating air from the outside of the housing 13 to the inside is located and reversed. Furthermore, in the described embodiment the cylindrical housing 13 is formed in two halves, the inner end of which has a complementary corrugated form. The half is spaced apart to define a sinusoidal cam track when assembled on the base. It is also provided for communication between the exterior of the housing 13 and its exterior to allow the outside air of the housing to circulate therein. If not necessary, a fan blade is also attached to the shaft 28 to allow air in the housing 13 to circulate while the shaft 28 rotates.

This rotary assembly is balanced to reduce vibration and excessive wear of the shaft 28 and the bearing assembly 30. In addition, the rotation of the rotary housing 13 and the horizontal reciprocating motion of the piston do not require the rotary assembly 26 to be operated as its own fly wheel and no external or additional fly wheel.

The compressor of the present invention has a minimum moving part and the movement into and out of the cylinder element is not very limited because of the large diameter of the port, which is extremely effective in that it is essentially the same diameter as the piston head. .

The efficiency of the compressor of the present invention will be explained in the following embodiments, in which compressors arranged as described in the embodiment of FIG. 1 are each one inch of bore 14 provided a compression ratio of 10 to 1 is provided. Four cylinder elements are provided and are accommodated to allow sliding of the piston 40 having a one inch stroke. The total size of the complete compressor described by this embodiment is 6 x 12 inches.

As described above, the compressor performs two complete cycles in one revolution so that the compressor is effectively a 16 cylinder compressor. Each piston head 42 is taken approximately 0.71 cubic inches during the suction stroke. Assuming 1000 revolutions per minute, the compressor will be compressed to approximately 11,312 cubic inches or 6.54 cubic feet at a pressure of 150 pounds per square inch. Increasing rotation of the rotary assembly 26 to 2250 rpm will increase the output of the compressor at 14.72 cubic feet per minute. This compressor has been tested at a maximum rpm of 40,000 rpm. It will be appreciated that by increasing the rpm of the rotary assembly 26 to 10,000 rpm, the pump will be able to output compressed air at 65.4 cubic feet per minute.

It should be understood that in the above embodiment the stroke and compression ratios are increased by extending the slot 48 of the cylinder element 36 such that the output of air is at a high pressure of 150 pounds or more. The size of the bore 14 of the cylinder and the circumference of the piston can be increased so that the output of the compressed air is increased. The size of the compressor can also be increased, and the number of cylinder elements and pistons may be increased, for example between 4 and 8 elements. However, this pump can also be operated effectively with two cylinder elements.

The apparatus described herein produces very high efficiency compressors and pumps for compressing or flowing fluids. It is operated with a minimum of moving parts which can be manufactured at a relatively low cost and can be easily maintained. However, the power plant of the present invention is easily converted to an internal combustion engine by changing only one or both end walls 16 of the device.

The same reference defense is formed by changing the end wall 16 'to include an air / fuel injection nozzle 59 and a glow plug 58 with reference to FIGS. A rotary power plant consisting of a complex internal combustion engine and a compressor is described. Port 60 is a suction port in communication with a suction manifold and a carburator (not shown) to deliver air / fuel to cylinder element 36. In the described embodiment, the rotary engine comprises four reciprocating pistons, each of which is operated in four stroke cycles while the rotary assembly rotates respectively. During the intake stroke, the air is drawn into the interior of each cylinder element 36 through the intake port 60, withdrawing from the end wall 16 ′ of the piston therein while rotating to align it with the intake port. / The fuel mixture is communicated to be sprayed. A glow plug 58 connected to a suitable electrical power source (not shown), such as an automobile battery, is located in the end wall 16 'at the upper dead center of the compression stroke of the piston and within the cylinder when they are aligned and rotated therein. It is operated by the method of burning the compressed air fuel mixture. Port 62 is in communication with the exhaust manifold (not shown).

In operation a stator motor (not shown) is connected to the shaft 28 in a conventional manner that causes the rotary assembly 26 to start rotating so that the internal combustion engine starts the engine. The pistons 40 may be applied to their respective cylinder elements 36 due to the action of the cam carriage 50 on the cam track 52 as described in connection with the compressor example of the invention described in FIGS. Reciprocating Each piston 40 is operated in a four-stroke cycle that sucks into the air fuel mixture from the nozzle 59 through the port 60. Taking one of the pistons, for example, when the rotary assembly 26 is rotated, the piston 40 moves to the end wall 16 'to compress the air / fuel mixture. At or near the upper dead center of the compression stroke, the cylinder element 36 including the compressed air / fuel mixture rotates to align with the glow plug 58 and the glow plug 58 burns the mixture to form an end wall ( The movement of the piston 40 is converted to the rotation of the rotary assembly 26 by adjusting the piston 40 in its power stroke apart from 16 'and by means of the cam longitudinal in the cam track 52. This cycle is repeated for each piston 40 as the rotary assembly 26 is rotated.

In the described embodiment, it should be understood that the side of the device opposite the end wall 16 'acts as a compressor in the manner described in connection with FIGS. 1-5. There is thus provided a compressor that is self-propelled as a single unit. However, both end walls 16 of the compressor designed in accordance with the invention may be modified such that the end walls 16 ′ completely convert the device from the compressor to eight in-cylinder combustion engines. In this case the end walls 16 ′ are switched relative to one another so that the opposite ends of each piston 40 are in opposite cycles. Similarly, the engine of the present invention is easily converted to a compressor by changing the end wall 16 ′ relative to the end wall 16.

As will be appreciated by those skilled in the art, various devices other than those described in the detailed description of the present invention can be achieved by those skilled in the art, but such devices are within the spirit and scope of the present invention. Is considered to be in It is therefore to be understood that the invention is only limited by the claims appended hereto.
