20090007770 | PNEUMATIC CYLINDER FOR PRECISION SERVO TYPE APPLICATIONS - A pneumatic cylinder designed to convert compressed air into mechanical output is disclosed. The pneumatic cylinder includes a piston and rod assembly with supporting components coaxially disposed and arranged to achieve a linear mechanical force in accordance with a differential pressure across the piston. A cylindrical sleeve, secured to end caps on both openings, encircles the piston and rod assembly and helps guide the piston during travel. A conductive coil is coupled to the cylindrical sleeve to provide sensing of a position of the piston. Additionally, a manifold, which serves as a conduit for airflow between each individual cylinder volume and an external air control device, is disposed such that the cylindrical sleeve and end caps are nested, in a concentric manner, within the manifold. A manifold divider assembly is disposed such that a plurality of end channels are isolated from each other. This arrangement results in a dynamic relationship between airflow and differential pressure that is conducive to precision force and motion control. | 01-08-2009 |
20100139475 | CUSHIONING SYSTEM FOR PNEUMATIC CYLINDER OF DIFFERENTIAL ENGINE - A cushioning system for a pneumatic cylinder powered differential engine door opening and closing device for use in passenger transportation vehicles wherein the cushioning initiation point can be adjusted. This cushioning initiation point is adjusted through the use of a linearly adjustable slider member within the large cylinder. The slider is linearly adjustable through the use of an adjustment screw located outside of the pneumatic cylinder and allows one to adjust the time and the mode of the opening/closing of power doors, without disassembly of the cylinder, and significantly improve the safety of the passenger. | 06-10-2010 |
20100258002 | ELMALEH ENGINE - A hydraulic/magnetic engine, comprising an engine assembly. Crankcase means are affixed within the engine assembly, and crankshaft means are positioned in the crankcase means. Cylinder means comprise at least two first cylinders being encased in the engine assembly and each including a first piston, at least two second pistons, and an electro-magnetic third piston. A hydraulic system has a hydraulic fluid chamber. First electro-magnetic means generates a first electromotive force, wherein switching magnetic polarity between a first and second openings forces a first piston, at least two second pistons, and an electro-magnetic third piston to move upward and downward within their respective cylinders. Thus, rotating the crankshaft means in a predetermined direction after an initial activation of the crankshaft means by applying a short period of an electrical force. The first electro-magnetic means is within the engine assembly. | 10-14-2010 |
20120060682 | Volume Booster With Reduced Noise Trim - A fluid flow control device having a body having a inlet connection, an outlet connection, a discharge port and a booster module disposed within the body. The booster module including a control element and an actuator element having a noise-reducing trim element with a supply path extending between the inlet connection and the outlet connection and an exhaust path extending between the outlet connection and the discharge port. The noise-reducing trim element being coupled immediately adjacent to the discharge port such that the noise-reducing trim element distributes a fluid flow to the discharge port via the exhaust path into a plurality of fluid jets to substantially inhibit jet recombination at the discharge port. | 03-15-2012 |
20120291623 | WORKING APPARATUS, IN PARTICULAR EXCAVATOR OR MACHINE FOR MATERIAL HANDLING - The present disclosure shows a working apparatus, in particular an excavator or a machine for material handling, having an element movable via at least one hydraulic working cylinder, wherein at least one energy recovery cylinder is provided for recovering energy from the movement of the movable element, said energy recovering cylinder being filled with gas at the base side and having an annular space filled with a medium. In this respect, a flow restricting element is provided which restricts the flow of the medium from the annular space on a sudden moving out of the piston rod. | 11-22-2012 |
20120318133 | HIGH-EFFICIENCY ENGINE DRIVEN BY PRESSURIZED AIR OR OTHER COMPRESSIBLE GASES - A negative-emission pressurized air or other compressible gas operated high-efficiency reciprocating or rotary piston engine, as autonomously considered or as part of a complex system, comprises at least a tank, at least a turbo-alternator and one or more optional fluid heaters. | 12-20-2012 |

20130061740 | VEHICLE USING COMPRESSED GAS, AND CONTROL DEVICE THEREFOR - A power unit that can periodically determine a leakage of a compressed gas to early discover a defect, such as a crack, and a vehicle in which the power unit is used are provided. A vehicle that runs with an air engine including a gas machinery includes a control device. The control device includes an adjuster that controls an output of the gas machinery such that a target output is obtained, a pressure measuring unit that measures the pressure of the compressed gas at the piping unit of the air engine, and a determination unit that determines a leakage state of the compressed gas based on a change in pressure, which is measured by the pressure measuring unit every time the target output of the gas machinery becomes substantial zero. The control device suspends the determination of the leakage state when the target output of the gas machinery changes from substantial zero during the determination. | 03-14-2013 |

20150033938 | COMBINED ELECTRIC AND HYDRAULIC MOTOR - The invention is a combined motor that combines or integrates electric and hydraulic power producing technologies into a single compact motor by means of common or shared rotor and stator elements. The invention allows optimized power, torque, performance and energy usage in electric and electric-hybrid vehicles and offers reduced weight and lower production costs due the use of common or shared components. The combined motor's electric and hydraulic power producing elements are preferably coaxial and coplanar, permitting axial compactness and enabling efficient space utilization in the vehicle. In typical electric vehicle drive cycles disproportionately large energy losses occur during the launch acceleration and brake energy recovery modes of vehicle torque demand. The combined motor increases overall efficiency by substituting high-efficiency hydraulic torque for low-efficiency electric torque during these modes. These peak efficiency substitutions conserve battery energy during launch acceleration, maximizing the state of charge to extend driving range or runtime. | 02-05-2015 |
