Rotary machine

A rotary machine in which plural, non-cylindrical rotors are provided for rotation within partially overlapping cylindrical bores, formed within a machine housing. Each rotor each said rotor has a curved outer surface formed of a plurality of contiguous mutually tangential curved portions.* The rotors are eccentrically mounted for synchronized, same directional rotation, within their respective bores, and each is arranged to alternately provide intake and exhaustion of working gaseous fluids, such that each rotor is continually either admitting or exhausting a working gas. The machine is constructed such that the rotors are cylindrical, each being of internally balanced form. The rotors do not touch each other or any portion of the machine casing at any time, while being positioned so as to define minimal gaps therebetween. A high rotational speed may be developed, thereby obviating the need for seals entirely, and thus further increasing the available speed, and thus the work efficiency of the machine.

Rotary piston engine with joint and cranked movement raises and lowers piston off and back onto support bearing in response to gas and spring pressure affording synchronous movement.

With its cam correctly positioned the sleeve connecting the frame and the piston (3) lifts the piston off and lowers it back onto the bearing (0) depending on tasking e.g. freewheel or gas or spring pressure. The sleeve is addressed automatically by spring from inside. The piston rotation axis is led outwards to provide synchronism for slide and joint relief. Gas exchange is afforded by a control disk joined forcibly by spring and gas pressure to the partition and powered by joint here operating as a crank for gas exchange control. The slide extends in a cylindrical piston bore and recess so in this way to prevent the joint tipping over with each position of rotation.

Rotary piston internal combustion engine

Rotary piston engine for motor vehicle

The engine comprises a compressor block (1) connected to a working block (2) by a combustion chamber block (8) onto which a combustion chamber (9) is mounted. There are sealing gaps (17,18) between the peripheries of the compressor rotor (4) or the working rotor (6) and the inner wall of their respective housings (3,5). The compressor and expansion areas are separated from the combustion chamber. There are movable sliders (12,13) guided in the compressor and working housings. The sliders are formed as stoppers which slide in each housing, contacting the rotors to form a suction chamber (19), compression (20), expansion (21) and exhaust (22) chambers. The stoppers oscillate under radial pressure.

Counter-rotating pump of simple design, high pressure and output and not comprising any friction or reciprocating movement, which can be reversed at any instant by simply reversing the direction of rotation

This design of pump has the feature of being very simple in operation, using only rotary movements. Theoretically there is no internal wear. Its output and its pressure are high for a small external bulk. It is reversible by simply reversing its direction of rotation. This pump implements the opposite rotation of two rotors which simultaneously create, during their movement, a suction chamber and a delivery chamber. The field of application of this pump is vast. It may of course replace numerous current pumps, but it may also operate as a compressor or internal combustion engine (disregarding the problems of sealing) or as a turbine or heat pump. A last field of application may be medical if it proves to have better performance than current artificial hearts.

Rotary piston internal combustion engine

A rotary piston internal combustion engine with two counter-rotating pistons (14, 15) located on the same axis and engaging with one another. One of the pistons acts as a compression or charging piston and the other as an expansion or propulsion piston. The design is aimed at providing a favourable co-ordination between the charging piston and the propulsion piston with the operating chamber of the propulsion piston being several times that of the charging piston, and is such that the two rotary pistons, whilst maintaining conjugate peripheral angles of approximately 360o, possess different peripheral lengths which leave in the rotary piston paths, operating chambers of different sizes, which take into account a pressure increase between the inlet air and the combustion gas. Furthermore, effective operation is achieved by annular valve slides (29, 30) which are incorporated in the housing on both sides of the rotary pistons, whose outer radii together are smaller than the distance of the rotary axes from one another. In this way it is also possible to obtain a symmetrical bearing system on both sides of the rotary pistons for high engine rpm.
