    摘要： A bleed valve assembly includes a valve poppet having a bleed portion and a base portion separated by a radially extending flange. The radially extending flange is located about the perimeter of the valve poppet to engage the valve seat on one side and receive a biasing member on the other. The flange engages the valve seat such that initial valve performance is similar to a disk valve, i.e., soft seating and very low leakage when closed. A plurality of openings extend through the bleed portion such that partial open operation of the bleed valve assembly is particularly tailored for a desired flow. As the valve poppet of the present invention moves off the valve seat, the initial gain is very low and then the gain increases steadily as more openings are exposed.

    摘要： A bearing assembly monitoring system provides continuous, real time monitoring of the operating condition of a powertrain support bearing assembly and real time alarm signals indicative of degradation and/or impending catastrophic failure thereof. One embodiment of the monitoring system includes a vibration sensing device, first and second primary temperature sensing devices, an ambient temperature sensing device, vibration and temperature signal processing subcircuits, and an alarm subsystem. The vibration sensing device monitors complex vibration signals emanating from the bearing assembly and provides signals corresponding thereto. The vibration signal processing circuit filters such complex vibration signals to provide a predetermined bandwidth thereof that are converted to stabilized DC voltage signals which are compared to reference voltages corresponding to higher than normal and excessive vibration levels. Exceedance of such reference voltages generates a corresponding vibration alarm signal. The temperature sensing devices monitor the operating and ambient temperatures of the bearing assembly and provide signals corresponding thereto. The temperature signal processing circuit converts such temperature signals to differential temperature signals which are compared to a reference voltage corresponding to a temperature differential indicative of impending catastrophic failure. Exceedance of the reference voltage generates a temperature alarm signal. The alarm subsystem is operative in response to the vibration and/or temperature alarm signals to provide a real time early warning of degradation and/or impending catastrophic failure of the bearing assembly.
