    Abstract: A variable performance valve for use in a fuel nozzle is presented. The valve includes a spring, an inner spool having a port, an outer sleeve, and an orifice, which in a fuel nozzle application may be a calibration orifice. In a low flow condition, the inlet to downstream pressure is the spring force divided by the area on which the pressure acts. At low flow the orifice does not cause any appreciable pressure drop. As the flow increases, a pressure drop develops across the orifice. Since the pressure drop across the valve cannot be greater than the spring force divided by valve area, the valve is forced to open to compensate. As flow is increased, the valve will stroke completely open and the pressure drop at the port becomes negligible and the pressure drop across the orifice is nearly 100% of the pressure drop across the valve.

  • Patent number: 7036523
    Abstract: Within a check valve, a spring urges a poppet into the closed position. If the fluid flow through the valve attempts to reverse, the poppet will seal against the valve seat by a combination of spring resistance and fluid pressure, thereby preventing all or a significant portion of fluid flow back through the valve body. The poppet is retained in the valve body by a retainer or other suitable part or combination of parts that can be removed for service of the check valve assembly.

  • Patent number: 6835053
    Abstract: In the check valve having a valve seat member and the valve member, the valve seat member is provided with first and second conical seats. The second conical seat is positioned upstream the first conical seat. An angle of the second conical seat to an axis of the valve member is more acute than that of the first conical seat. Since the check valve has the second conical seat, contact pressure applied to the first conical seat is uniformly dispersed and, thus, the first conical seat is less worn out. Further, the second conical seat prevents the valve member from cutting into and sticking to the valve seat member, even if the wear has been progressed. Accordingly, an operation of the check valve is stable for a longer period of time.
