摘要： A solenoid actuated valve for regulating the fluid pressure at a control port by cyclically connecting the control port alternately to a fluid pressure supply source and to a sump includes a sleeve-like valve member slidably mounted on a fixed valve member for movement between two positions in response to energization or deenergization of the solenoid coil. The valve sleeve is the armature of the solenoid and operates within an internal chamber in the valve housing with pressure within the chamber balanced against its opposite ends. Energization and deenergization of the solenoid coil may be controlled by a processor which supplies a pulse width modulated electric control signal variable in response to processor inputs to establish a control port pressure which is accurately linearly related to the time duration of the pulse width modulated signal.

摘要： A fuel pressure regulator is shown as having two distinct and variable chambers sharing, as a common wall therebetween, a pressure responsive diaphragm which controls the position of a valve actuator depending upon the pressure differential existing across the diaphragm with such pressure differential being reflective of the pressure differential existing as from the magnitude of the pressure of the fuel in a first of the two chambers to the magnitude of the pressure within the second of the two chambers which is at ambient atmospheric pressure; a flapper type valve openable by the valve actuator serves to control the flow of fuel into the first of the two chambers from where the pressure regulated fuel flows as to associated fuel metering apparatus.
