| Number | Title | Issue Date |
| 8092149 | Impeller arrangement An impeller arrangement comprises an impeller 10 having at least one first vane surface 26 orientated such that the application of fluid under pressure thereto applies a torque to the impeller 10 in a first rotary direction, at least one second ... | 01/10/2012 |
| 7314347 | Pressurized fluid bladeless turbine engine with opposing fluid intake assemblies A bladeless pressurized fluid turbine engine having a bladeless turbine, internal, concentric or circumferential shaft fluid ways which transmit pressurized gas to the turbine, and a pair of opposing pressurized fluid intake assemblies. Each intake assembly has a fi... | 01/01/2008 |
| 7198456 | Floating head reaction turbine rotor with improved jet quality A rotary jetting tool including a pressure-balanced rotor, which is achieved using a vented volume. Axial movement of the rotor relative to the housing caused by pressure imbalances acting on the rotor selectively uncovers or opens a vent that places the volume in f... | 04/03/2007 |
| 7077732 | High torque dual chamber turbine rotor for hand held or spindle mounted pneumatic tool A high torque turbine rotor for a lightweight hand held tool for grinding and polishing having a rotor that includes two separate high pressure air chambers separated by a common housing wall, each air chamber having peripheral air expelling nozzles in a tangential ... | 07/18/2006 |
| 6997674 | Pressurized fluid turbine engine A bladeless pressurized fluid turbine engine having a bladeless turbine, internal, concentric or circumferential shaft fluid ways which transmit pressurized gas to the turbine, and a pressurized fluid intake assembly. The intake assembly has a fixed outer housing, t... | 02/14/2006 |
| 6565310 | Steam-powered rotary engine A steam-powered rotary engine is provided in which a rotor arm assembly and an outer ring are positioned such that steam ejected from outlets at the two ends of the rotor arm assembly will impact at a substantially right angle onto steps or depressions fo... | 05/20/2003 |
| 5439346 | Pneumatic pressure automatic braking mechanism A braking mechanism for a rotary apparatus having a housing adapted to receive a pressurized fluid and a rotor rotatably mounted in the housing. The braking mechanism enables the rotor to rotate in the housing in response to the receipt of the pressurized... | 08/08/1995 |
| 5186603 | Air motor The air motor of the present invention has an air chamber for taking compressed air in a rotor body fitted to a rotary shaft, forms a jet hole opening in the tangential direction of the rotor on the periphery of the rotor, jets compressed air from the jet... | 02/16/1993 |
| 4776752 | Speed governed rotary device A governor device for controlling the speed of rotary devices is disclosed. The governor device is a valve operated by centrifugal force to control a pressurized fluid through the nozzles of a turbine rotor. The valve comprises a rotary chamber having an ... | 10/11/1988 |
| 4408951 | Fluid driven engine A speed governor for engines which comprises a rotary hollow shaft receiving exhaust fluid at one end, a conduit and nozzle assembly connected at the other end of the rotary hollow shaft and including a needle valve, a turbine housing in which at least on... | 10/11/1983 |
| 4406121 | Rotary fluid device 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 experi... | 09/27/1983 |
| 4302683 | Reaction engine driven electrical generating system with power load variation control capability A reaction engine driven electrical generating system comprising an electrical generator having an armature and a reaction engine driven to rotate the armature for generating electricity. The reaction engine drive includes a generally cylindrical housing ... | 11/24/1981 |
| 4087198 | Speed governed rotary device A rotary device with a speed governor as a part of a centrifugally radially expandable rotor and having radially adjustable prestress means for preselecting the maximum speed at which the governor operates to limit the speed to this maximum. The rotor whi... | 05/02/1978 |
