| 61 | Steam-driven engine | US32020273 | 1973-01-02 | US3873245A | 1975-03-25 | DOSHI NIRANJAN KUMAR |
| A positive-displacement, steam-driven engine has a generallyelliptical rotor which is mounted on a shaft that is eccentric of a cylindrical chamber. The rotor has an elongated slot which is parallel to its major axis, and that slot accommodates that shaft. The rotor reciprocates along its major axis as it rotates within the cylindrical chamber. Seals are provided between the rotor and the inner surfaces of the cylindrical chamber to enable the engine to operate as a positive-displacement, steam-driven engine.

| The units contain pairs of toothed intermeshing members running on axes that intersect at an angle differing from 180* by half the tooth-height angle. Their tooth numbers differ by one. Ducts lead fluid to and from the intermeshing members. In units containing two of said pairs their larger members are coaxial and form a rigid rotor. The invention gears this rotor directly to the outside, without driving through the smaller member of one pair. It thereby minimizes the load transmitted through the tooth sides of each pair. The shaft geared to said rotor is positioned to minimize the bearing loads thereof. Generally the shaft axis lies in an axial plane of said rotor inclined to the plane of the axes of each of said pairs. The improvement further resides in the mounting of the smaller member of a pair and in the shape of the duct openings at the intermeshing members.

| 63 | Control means for bidirectional rotary fluid motor system | US3614275D | 1969-11-13 | US3614275A | 1971-10-19 | EIBSEN RICHARD S |
| A control means for a bidirectional, rotary fluid motor means constructed and arranged to have porting and fluid working chambers to provide rotation of a rotor in one direction or the opposite direction. The control means comprises a control valve connected to communicate with the fluid motor means and a pressurized fluid supply means and a fluid exhaust or return means so that pressurized fluid fills or ''''floods'''' the fluid motor, including the ports and working chambers, in the neutral or null position of the control valve to thereby cause equal and opposite torque forces on the rotor and prevent rotation of the latter, and in another operative position of the valve effect an imbalance of torque forces on the rotor so as to cause rotation of the rotor in one direction or the other with a minimum time lapse.

| 65 | Rotary steam engine | US3578890D | 1970-04-09 | US3578890A | 1971-05-18 | JENSEN OLUF F |
| A rotary steam engine comprising a housing including at least first and second power units mounted therein. Each of power units include a pair of cylinders in communication with each other and having two rotors rotatably mounted therein. The rotors have peripheral gear teeth extending therefrom which are in mesh with the gear teeth of the other rotor. A rotary valve is centrally positioned in the housing with respect to the rotors and is adapted to successively supply steam to the power units to cause the rotation of the rotors therein. Each of the rotors have a drive shaft connected thereto which extend outwardly of the housing. A gear is mounted on the outer ends of each of the drive shafts. The gears on the drive shafts of the first power unit are in mesh with each other with the gears on the rotors of the second power unit also being in mesh with each other. The rotary valve has a drive shaft connected thereto which extends outwardly from the housing with a drive gear being secured to the outer end of the drive shaft. The drive gear is in operative engagement with one of the gears of the first power unit and in operative engagement with a gear of the second power unit. Rotation of the rotors causes the rotary valve to be rotated so as to admit and cut off the steam supply to the rotors at the proper times. The rotary valve is provided with a steam discharge opening which has an increasing opening area from one end thereof to the other end thereof to permit the rotary valve to be longitudinally moved with respect to oppositely disposed steam passageways to permit the amount of steam passing therethrough to be varied.

| A fuel delivery system for a combustion engine has a fuel tank which defines an access hole preferably communicating through either the top wall or bottom wall of the tank. An associated top or bottom flange, both having a fuel channel for flowing fuel out of the tank, sealably covers the access hole. A fuel pump module is located in the fuel chamber of the tank and has a universal, structural, pod which engages either the top or bottom flange while preferably maintaining an axial upright position. The pod defines an axially extending first bore for housing a fuel pump and preferably an electric pump motor and a second bore defined by a cylindrical inner face and spaced radially outward from the first chamber for housing a reversible filter cartridge of the module. The pod also has a fuel discharge nozzle which generally defines a counter bore that communicates axially with the second bore. Fuel flows into the pump through an inlet defined by the pod and pressurized fuel flows from the pump and into the second bore via a fuel passage preferably defined by the pod. The filter cartridge preferably has a filter element generally spaced from the pod within the second bore for filtration efficiency by a primary end retainer and an opposite secondary end retainer. The end retainers generally seal to the pod within the second bore thus flowing all of the pressurized fuel from the fuel passage and through the filter element before being discharged from the second bore as supply fuel and/or bypass fuel. Preferably, filtered fuel flows through the primary end retainer as system supply fuel to a combustion engine and the remaining filtered fuel flows through the secondary end retainer as bypass fuel back into the fuel tank chamber. | ||||||

| A rotary external combustion engine wherein energy is supplied to a working space of the engine by direct injection into the stator of liquid water at a high temperature and pressure. The water acts as a heat-transfer medium. Some of the liquid water spontaneously vaporizes on injection, during the rotor.

| 77 | Two-stage rotary engines | US556433 | 1975-03-07 | US3970050A | 1976-07-20 | Harry W. Hoadley |
| A pair of sealed engine rotors are connected by links and cranks to a single shaft for simultaneous operation one-quarter turn out of phase. The use of internal gears and eccentrics for driving the two rotors is avoided. The expanding charge in the chamber containing the second rotor is diverted back into the chamber for the first rotor whereby this charge may further expand and assist in driving the first stage rotor. The rotor chamber profiles are free of abrupt humps, thus avoiding seal shock and wear and chatter marks on chamber surfaces. Vaporized fuel is utilized to cool the engine by passage through the centers of the rotors. Increased compression, greater rotor speed and more usable power are fully-achieved features. | ||||||

In a 2-element rotary mechanism, one camming element has a simple cam profile and the other has follower rollers. A 3-element mechanism has a third camming element to provide two sets of cam profiles and follower rollers. When used as a fluid pressure device, it is mounted in either of two ways: (a) with each of the three elements on a unique fixed axis or (b) with the outer and inner elements on common fixed axes and the intermediate element floating, its axis orbiting said common axes. For valving the latter arrangement, at least one inboard rotary valve plate turns with the intermediate element, and an outboard, usually stationary, valve plate is attached to the outer element adjacent each rotary plate.
