ABSTRACT:
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. The pressure-responsive surface of the valve sleeve is a substantially continuous frustrum of a cone whose apex extends in the direction of the valve opening and which extends radially outward from a sleeve inner diameter A to an outer diameter C (point C) of discontinuity in that surface. Point C is radially outward of the spindle and sleeve centerline at least as far as the point of intersection, B', with that frustoconical pressure-responsive surface of a line normal to the surface and extending through the control edge D when the sleeve is fully-open. The minimum radial positioning of discontinuity point C is a function of the angle of the pressure-responsive surface and the stroke of the sleeve. The high pressure plenum is structured to enhance the valve-opening rate.
