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 governor system for an engine motive fluid induction system is shown as having a solenoid operated valve assembly communicating with a source of vacuum and with a vacuum motor assembly operatively connected to a variably positionable throttle valve of the induction system; an electronic control sensitive to the speed of a monitored parameter is effective to controllably energize the solenoid valve assembly to in turn regulate the magnitude of vacuum directed thereby to the vacuum motor assembly and consequently govern the then permissible amount of opening of the throttle valve.

摘要： A pressure control device, preferably for use in a control system of an automatic transmission of a motor vehicle, is shown as having a solenoid motor assembly the armature of which, through a cooperating servo orifice, is effective for varying the magnitude of pressure of a fluid medium acting upon a spool slave-like valving member which ultimately provides a fluid medium to associated fluid medium receiving structure; a fluid medium flow restriction formed as of sintered metal enables the fluid medium to flow in and through the control device to thereby bring about purging of air and other gases from within said control device.
