  • Patent number: 9596047
    Abstract: An implement method of reservation protocol with multi-services convergence transmission for OBS networks differentially processes the synchronous service flow and the asynchronous service flow, and assembles multiple different types service data into different data burst (DB) by generalized optical-burst paradigm. It functionally expands burst control packet (BCP) and classifies the BCP into two categories: routine burst control packet (R-BCP) and synchronous trace burst control packet (T-BCP). Then it can differentially reserve wavelength channel resource and preempt resource to try to keep the transmission features of synchronous service such as period, low delay jitter and low dropping probability on the base of ensuring the basic QoS requirements of various kinds of service, and realize that a single OBS network efficiently provides asynchronous service and synchronous service.

  • Patent number: 7341236
    Abstract: A pilot operated valve has a main poppet that selectively controls flow of fluid between first and second ports in response to pressure in a control chamber on one side of the main poppet. The main poppet has an aperture extending between the control chamber and the first port. A pilot piston slides within the aperture and has the pilot passage with a pilot orifice and a first disk spring biases the pilot piston with respect to the main poppet. A pilot valve element selectively engages the pilot orifice to open and close the pilot passage and thereby controls motion of the main poppet. Forces from the first disk spring and a pressure differential between control and pilot chambers alter a position of the pilot valve seat with respect to the main poppet. The change in position compensates for effects on valve operation due to variation of the pressure at the two ports.

  • Patent number: 6745992
    Abstract: A pilot operated valve has a main poppet that selectively controls bidirectional flow of fluid between two ports in response to pressure in a control chamber on one side of the main poppet. The main poppet has a pilot orifice that is opened and closed by a pilot poppet. A unique mechanism is provided to compensate for variation of a pressure differential on opposite sides of the pilot orifice. This mechanism has a pair of annular end members between which extends a spring formed by a plurality of helices. Multiple passages with check valves extend through the main poppet to communicate the greatest pressure among the two ports to the control chamber and the lowest pressure among the two ports to the side of the pilot orifice that is opposite the control chamber.

  • Patent number: 6149124
    Abstract: A pilot operated control valve has a body with an inlet and an outlet. A main valve poppet is movable within the body to selectively control flow of fluid between the inlet and outlet. The main valve poppet has a flexible diaphragm with a pilot passage therethrough which is opened and closed by movement of a pilot poppet. The diaphragm flexes due to a pressure differential that acts on the pilot poppet, which flexing compensates for adverse effects that the pressure differential has on the operation of the pilot poppet.
