  • Slow-opening valve operated by a solenoid pump
    Patent number: 4247077
    Abstract: A slow-opening valve including a main valve, a chamber for receiving a control fluid other than that controlled by the main valve, and a member within the chamber responsive to the volume of control fluid in the chamber for opening and closing the main valve. A solenoid pump, including an armature and an electrical solenoid for vibrating the armature, produces fluid flow in small increments with respect to the chamber to effect opening of the valve. An auxiliary valve, which opens and closes in response to the position of the solenoid pump armature, controls flow of fluid with respect to the chamber for closing the main valve.
