A normally-open, solenoid-controlled valve includes a stationary valve-seat spindle and a cylindrical valve sleeve encircling and slideable along part of the valve-seat spindle. The valve-seat spindle has an annular control edge and the valve sleeve includes a pressure-responsive surface which is reciprocably moved into and out of valve-closing contact with the control edge. The valve-seat spindle includes a flow passage therein extending to and discharging into a plenum region formed radially inward of the control edge between the spindle and the sleeve...
In a valve for controlling the flow of liquid between a high pressure supply and a relatively lower pressure drain, the valve comprising: a stationary valve-seat spindle having a first axial portion of one diameter and a second axial portion of greater diameter, an annular control edge of greater diameter than said first portion being formed on said second portion, said control edge having a radius D from the centerline of said spindle; a cylindrical valve sleeve closely encircling said first portion of said seat spindle in axial sliding relation therewi...
