  • Publication number: 20120079901
    Abstract: This invention relates to a novel helical dual-center engagement converting mechanism and its applications in fluid-powered actuation system, more particularly to a highly reliable, simple, powerful and balanced and less expensive helical rotary actuator. This actuator comprises a self-balanced linear/rotary dual-center engagement converter, compact porting systems and easy manufacturing modules and various bodies and shaft interface with other components. This actuator also provides a rotary position control and backlash eliminating mechanism to meet various requirements with lighter weight, smaller size and higher accuracy of position and can be interfaced with different machines, such as subsea valves, earthmoving equipment, construction equipment, lifting equipment, landing gears, militarily equipment and medical devices, robotic and artificial leg and arm joints.

  • Publication number: 20080203346
    Abstract: This invention provides a fluid control system for regulating flow fluid under extreme conditions and includes a reciprocal a reciprocal 1 control module and rotary control module. This system provides energy transmission devices to regulate a flow fluid rate and flow fluid pressure in different manners with minimum pressure loss consequences. This system also has a dynamic stem seal assembly which comprises an inclusive stem packing, bore packing, and secondary seal for compensating any offset and is provided with a leakage between 10-500 ppm and a controllable loading device and a dynamic seat seal assembly which comprises a body seal and valve member seal for compensating any offset and is provided with zero leakage and novel mapped solutions with a metal-to-metal seal ultimate goal-pointed seal ring. This system provides a number of novel mechanical joint devices.

  • Patent number: 7334514
    Abstract: This invention provides a modular, efficient and self-feedback/balance, fluid-powered actuation system. This system comprises two basic modules; actuation module and positioning module, which are directly connected to each other. The actuation modules can be constructed as a triple acting actuator having a novel balanced linear-rotary mechanism converter or a double acting actuator with two novel balance guide bars. The positioning module is constructed as a two-staged, self-feedback/balance positioner with position as a variable for controlling positions of an output shaft of the actuation modules. An input shaft in the positioning module is operated by three types input signals. This system also provides a rotary force to actuate and control different rotary valves with lighter weight, superior seal and high accuracy and can be used for quick cycle, high vibration applications or other critical services.

  • Publication number: 20070193632
    Abstract: This invention provides a simple, rotary, reliable, compact, anticoagulant, artificial or mechanical heart valve based on two rotary pressure porting mechanisms. This valve provides one center flow stream without any obstruction which only human heart valve can provide so far. It employs about ? of the energy that the conventional mechanical heart valve consumes. This mechanical heart valve includes three basic configurations with one leaflet, two and three leaflets for various human heart valve replacement. This valve has the most reliable designs over all existing mechanical heart valves. The reliable features includes less moving part, dual redundant hinge—actuation system and inclusive designs; either loosing proof or falling out proof. Finally most importantly, the invention is provided with an unique anticoagulant mechanisms which include mechanical and medical methods to clean up clots and prolong life of this valve up to 20-40 years.
