| 121 | Rotary type fluid machine, vane type fluid machine, and waste heat recovering device for internal combustion engine | US10321443 | 2002-12-18 | US20030084866A1 | 2003-05-08 | Tsuneo Endoh; Kensuke Honma |
| Rotary type fluid machine includes a casing 7, a rotor 31 and a plurality of vane-piston units U1-U12 which are disposed in a radiate arrangement on the rotor 31. Each of the vane-piston units U1-U12 has a vane 42 sliding in a rotor chamber 14 and a piston 41 placed in abutment against a non-slide side of the vane 42. When it functions as an expanding machine 4, the expansion of a high pressure gas is used to operate the pistons 41 thereby to rotate the rotor 31 via vanes 42 and the expansion of a low pressure gas caused by a pressure reduction in the high pressure gas is used to rotate the rotor 31 via the vanes 41. On the other hand, when it functions as a compressing machine, the rotation of rotor 31 is used to supply a low pressure air to the side of pistons 41 via vanes 42 and further, the pistons 41 are operated by the vanes 42 to convert the low pressure air to the high pressure air. Thus, a rotary type fluid machine having expanding and compressing functions, with the merits belonging to the piston type and the merits belonging to the vane type, can be provided. | ||||||
| 122 | Fluid displacement pump with backpressure stop | US09780302 | 2001-02-09 | US20010009150A1 | 2001-07-26 | Arthur Vanmoor |
| The fluid displacement pump enables substantially continuous pumping from a low-pressure side to a high-pressure side substantially without any backflow or backpressure pulsations. Liquid or gas is injected to the high-pressure side by way of mutually intertwined worm spindles that form a fluidtight displacement system. The blades of the impeller system are almost flat, i.e., their attack angle relative to backpressure is close to perpendicular so that they will turn quite freely in the forward direction, but will not be turned backwards by a pressurized backflow. The impeller rotation that is introduced via the spindle shafts nevertheless leads to a volume displacement towards the high-pressure side, for instance, towards a chamber to be pressurized or to be subjected to equal pressure. The impeller system can be driven with variable speed, which translates proportionally in a variable pressure buildup. | ||||||
| 123 | Internal combustion engine with substantially continuous fuel feed and power output | US09503665 | 2000-02-14 | US06257195B1 | 2001-07-10 | Arthur Vanmoor |
| The internal combustion engine allows charging with an air/fuel mixture into the combustion chamber while the combustion chamber is under combustion pressure and outputs power virtually continuously at the same time, i.e., the novel engine has an almost continuous fuel feed and, due to substantially continuous combustion, it also has an almost continuous power output. The fuel and/or air is injected by way of mutually intertwined worm spindles that form a fluidtight displacement system. The blades of the impeller system are almost flat, i.e., their attack angle relative to backpressure is close to perpendicular so that they will turn quite freely in the forward direction, but will not be turned backwards by a pressurized backflow. The impeller rotation that is introduced via the spindle shafts nevertheless leads to a volume displacement towards the chamber to be pressurized or to be subjected to equal pressure. The impeller system can be driven with variable speed, which translates proportionally in a variable pressure buildup. | ||||||
| 124 | arc-piston engine | US046905 | 1998-03-24 | US6021746A | 2000-02-08 | Sang-Bok Pyon |
| An engine having an annular cylinder formed about an opening which utilizes an arc-piston reciprocally positioned in the annular cylinder with a partition secured within the annular cylinder separating the annular cylinder into an air intake compression chamber and a gas combustion chamber such that in use upon reciprocation of the arc-piston one of the chambers is expanding while the remaining of the chambers is contacting is disclosed. Within the opening a conventional gas turbine may be positioned and the rotational power of the arc-piston engine is combined with the rotational power of the gas turbine. | ||||||
| 125 | Rotary piston engine | US67922 | 1979-08-20 | US4250851A | 1981-02-17 | Robert Truck |
| An engine having a drive shaft secured to a rotary piston mounted within a casing. An intake-compression chamber between the casing and piston is supplied with fuel through an intake port. The rotary piston has an annular expansion-exhaust chamber and an exhaust port on the casing communicates with that chamber. A drive flap pivotally mounted on the piston swings into and out of the expansion-exhaust chamber between open and closed positions as the piston rotates, the flap thus forming a movable pressure barrier extending across the expansion-exhaust chamber. The piston has a plurality of turbine slots circumferentially spaced apart in a direction extending away from the direction of rotation of the piston so as to sweep successively across the combustion chamber and connect said chamber to the expansion-exhaust chamber. Also, a cam member is carried by the casing to project into the expansion-exhaust chamber, the member being positioned to control movement of the drive flap between the open and closed positions in timed relation to ignition of a combustible mixture within the combustion chamber. The engine produces power at high rotational speeds which are possible because of the absence of oscillating masses which must be accelerated and retarded as is the case in a conventional piston engine. | ||||||
| 126 | Gerotor type fluid motor, pump or the like | US44899374 | 1974-03-07 | US3905727A | 1975-09-16 | KILMER JOHN B |
| Improved fluid-mechanical and mechanical-fluid energy translation devices, such as fluid motors, pumps and certain actuators, meters, couplers and the like of the type having an orbital member disposed between a rotor element and a stator element and coupled with one of the elements by fluid displacement means and with the other element by gear means, are provided by employing therein a plurality of eccentric means for positively but shiftably mounting the member upon the element to which it is coupled by fluid displacement means in manner restricting relative motion between the member and the lastmentioned element to relative orbital motion. The element upon which the member is thus mounted may be either a rotor or a stator element and may be either the inner or the outer of the elements in various embodiments of devices incorporating the invention. The eccentric means, which are essentially cranks or shafts with offset axes, significantly are alone sufficient to accomplish the positive, shiftable mounting of the member and the restriction of same to relative orbital motion and to do so quite independently of any other fluid and mechanical couplings that may exist between the member and the elements in various particular forms of devices. The preferred embodiment also provides a further improvement in devices of this type employing vanes to define fluid displacement chambers by arranging the parts to maintain the pair of vanes bounding each chamber parallel to each other throughout the operating cycle, thereby maintaining the chordal transverse cross-sectional area of each chamber substantially constant throughout such cycle. The devices embodying the invention are characterized by increased efficiency and reliability, reduced wear on certain primary parts, and greater economy of manufacture by virtue of reduced strength and looser tolerance requirements in connection with certain primary parts.
