  • Patent number: 6435472
    Abstract: Proportional variable force solenoid valve for controlling the pressure of a fluid in a fluid control system comprises a solenoid housing having therein a solenoid coil, an armature movable in response to electrical current applied to the solenoid coil, and a biasing spring for biasing the armature in a direction to establish a valve fluid pressure response to solenoid coil current. An inner armature end cooperates with or engages a damping member residing in a fluid damping chamber to reduce non-linear valve responses resulting from pressure oscillations in the fluid control system.
    Type: Grant
    Filed: April 25, 2001
    Date of Patent: August 20, 2002
    Assignee: Saturn Electronics & Engineering, Inc.

  • Patent number: 6019120
    Abstract: A solenoid actuated valve for regulating the pressure of a pressurized fluid in a fluid control system in proportion to the current level of an electrical input signal including a nozzle housing having an end connected to a solenoid housing and a fixed fluid flow directing tubular sleeve internal thereof and communicated to a supply port for receiving pressurized fluid therefrom. The sleeve includes a primary orifice communicating to a valve seat proximate the end of the nozzle housing and to a control port located proximate a second end of the nozzle housing via one or more longitudinal fluid passages between the nozzle housing and the sleeve. The sleeve includes a secondary bleed orifice located proximate the control port to bleed pressurized fluid thereto in a manner to provide more precise low pressure fluid control.

  • Patent number: 5845667
    Abstract: A pressure regulating variable force solenoid fluid control valve for regulating the pressure of a pressurized fluid in a fluid control system in proportion to the current level of an electrical input signal comprises a supply port for receiving pressurized fluid, a control port in fluid flow communication to the supply port via a primary orifice, the control port communicating with an external component, such as a hydraulic automobile transmission component to control operation thereof, and a variable force solenoid actuated valve that cooperates with a valve seat receiving pressurized fluid from the primary orifice to control flow of pressurized fluid to one or more exhaust ports as a means to regulate pressure at the control port in dependence upon electrical current to a coil of the solenoid actuated valve.
