20140298981 | ENERGY GENERATOR - The energy generator relates to the field of mechanical engineering, in particular to rotary actuator devices. The device comprises a housing, in which a drive shaft is installed; a driving link, which includes a mechanism for transmitting the rotation of the shaft to elements with an unbalanced mass via a driving wheel that is installed on the drive shaft; a kinematic chain between the driving link and a final consumer, which comprises working nodes which are able to transfer a working moment. According to the claimed technical solution, the driven eccentric wheels are mounted so as to be capabie of rotating on additional stationary driven axles, rigidly connected to one another at both ends thereof by a coupling element, namely a rocker arm. The driven axle is equipped with an additional coupling link, which is connected to a movable element of a working chamber with a variable volume; the chamber is connected via a receiver with the final consumer. The device may comprise additional driving wheels and additional driven eccentric wheels that are connected to the same driving wheel and rigidly attached to the same rocker arm in series. | 10-09-2014 |

20130133511 | FLUID ROTARY MACHINE - A fluid rotary machine with a decreased footprint and a reduction in the number of parts. The fluid rotary machine has four heads wherein double-headed pistons are disposed inside cylinders in a crisscross arrangement. The rotational balance between rotational parts including the double-headed pistons is achieved only by first and second balance weights which are inserted and incorporated into both ends of a crank shaft coupled eccentrically to a shaft. The shaft is rotated for the double-headed pistons to linearly reciprocate in the cylinders. The fluid rotary machine has rotary valves for switching between the suction and discharge operations of the fluid for each cylinder chamber. The rotary valves are incorporated into a case to be coaxial and integrally rotatable with the shaft. | 05-30-2013 |

20130180395 | Oil-Pressure Apparatus - An oil-pressure apparatus is provided with an actuating cylinder that works on the outside and an acceleration cylinder that does not work on the outside. When a rod of the actuating cylinder is extended with no load applied to the actuating cylinder, oil is supplied to the actuating cylinder through the acceleration cylinder so that extension of the rod is accelerated. When the rod of the actuating cylinder is extended with load applied to the actuating cylinder, oil is adjusted to the actuating cylinder without passing through the acceleration cylinder so that original thrust of the actuating cylinder is exerted. | 07-18-2013 |
