  • Patent number: 5141389
    Abstract: The axial forces imposed on a rotor of a fluid machine such as a compressor is controlled by modulating the pressure supplied to a piston and cylinder device acting between the rotor shaft and housing. A parameter indicative of axial force on the rotor during operation is monitored and changes in the magnitude and direction of the axial forces countered by varying the pressure in the cylinder. The net axial forces imposed on the shaft may thus be controlled in a predetermined range.

  • Patent number: 4445327
    Abstract: This engine is designed to be operated by diversity of methods. It comprises a master cylinder which has the shape of the capital letter "T". Oil is compressed in this cylinder from its vertical line. The two opposite sides of this master cylinder have conical channels in them. Next to each side of the master cylinder and outside it, there is a rotating disc with poaches or pockets in it. Deep in each poach there is a draining duct which opens in the thickness of that rotating disc. The two rotating discs are attached together by an axle crossing the master cylinder from one side to another. As the assembly is tight, and if an amount of oil is compressed in the master cylinder through its vertical or pumping line, then the oil will have no passage out of it except through the conical channels of the cylinder's sides.And as oil gushes under pressure from the sides it encounters the rotating disc with the poaches, and thus forces it to spin to be able to get out from it.

  • Patent number: 4406121
    Abstract: A multiple stage energized fluiel flywheel is contained within a housing. An axially extending shaft is rotatably mounted within the housing. Fluid is introduced into the unit through an initial axial flow section and further pressure increases are experienced in a radial blower section and an annular squirrel cage section peripherally arranged about the radial blower. Pressurized fluid discharged from the squirrel cages is directed to either a peripheral exhaust ring which discharges pressurized fluid to the reservoir interior or to an adjacent hydraulic motor. The hydraulic motor includes a rotor which is secured to the stator section of the initial axial pumping section. The axial shaft, radial blower, squirrel cage and exhaust section rotate as a unit in one direction of operation. The hydraulic motor and axial pumping section stator rotate as a unit in the opposite direction of rotation. The flywheel may operate using air, hydraulic fluid or other motive fluids.

  • Patent number: 4048798
    Abstract: An engine which includes a combustion chamber and a work function chamber enclosing the combustion chamber. A burner means is located in the combustion chamber for combustion. A rotatable turbine wheel is further mounted in an inlet of the work function chamber with one side of the blades in communication with the ambient atmosphere and the other side in communication with the interior of the work function chamber. The products of combustion are rapidly cooled and continuously removed from the combustion chamber by an exhaust means of the venturi type. This serves to create a pressure differential and provide a continuous stream of high velocity airflow against and through the blades of the turbine, through the work function chamber and out through the exhaust means. In this manner, a rapid rotative movement is provided for the turbine wheel and power output is taken from it and from the output shaft on which it is mounted.
