摘要： A valve for combining exhaust gas from an engine combustion chamber with engine intake gases. The valve includes a valve body having a gas inlet and a gas outlet connected by a throughpassage. A flow control member supported by the valve body regulates flow through the valve body throughpassage. A magnetic drive is supported for movement with respect to the valve body and coupled to the flow control member to regulate flow in the throughpassage. An electronically actuated field-generating solenoid moves the magnetic drive member to control flow through the valve body.

摘要： A test circuit for testing operation of a liquid level detector. The liquid level detector includes a probe that is placed at a test site. A control circuit monitors changes in capacitance of the probe due to changes in the liquid level at the test site. A test switch grounds an input to the probe which and causes the control circuit to sense an alarm condition. If the detector does not activate an alarm when the test switch is actuated, the detector is not properly functioning and repair or replacement of the level detector is needed.

摘要： An engine control system is disclosed having a unit for providing signals indicative of the position of an engine throttle member. The unit comprises a housing assembly associated with an engine throttle member and containing a stator assembly and a rotor assembly. The rotor assembly moves relative to the stator assembly as the throttle member moves. The rotor and stator assemblies are electrically coupled together for producing first and second continuously variable, ratiometrically identical signals whose values depend upon the throttle member position. The first signal is delivered from the housing assembly for use in controlling the engine operation. Processing circuitry processes the second signal for producing a throttle position validation signal having a first value when the throttle member is in an engine idle range of positions and a second value when the throttle member moves beyond the idle range of positions. If the first signal and the validation signal signify incompatible throttle member positions the engine speed is limited to "idle."
摘要翻译：公开了一种具有用于提供指示发动机节气门构件的位置的信号的单元的发动机控制系统。该单元包括与发动机节流构件相关联并包含定子组件和转子组件的壳体组件。当节流构件移动时，转子组件相对于定子组件移动。转子和定子组件电耦合在一起，用于产生第一和第二连续可变的，比例相同的信号，其值取决于节流构件位置。第一信号从壳体组件传送用于控制发动机操作。当节流构件处于发动机空转位置范围时，处理电路处理第二信号以产生具有第一值的节气门位置确认信号，当节气门构件移动超过位置的空闲范围时，处理电路处理第二信号。如果第一个信号和验证信号表示不兼容的节气门构件位置，则发动机速度被限制为“空转”。
