Abstract:

A fast-response solenoid valve. A three-way form has a body with three successive separated openings interconnected by a linear fluid pathway having two chambers lying between successive pairs of openings, each with a movable ball and a ball seat in respective ball cages. Each cage has a cylindrical exterior wall in snug engagement with the wall of the linear fluid passageway, a seat at one end, and a tanged retainer portion at the other end, so that, each ball is retained in its cage for limited axial movement between its seat and its tanged portion. A cylindrical non-magnetic tube is aligned with the linear fluid pathway, one end of the tube abutting a portion of the body. A non-magnetic end plug is held at a fixed position at the distal end of the tube, and a magnetic guide plug is held at a fixed position in the tube spaced away from the end plug. A solenoid plunger is in said tube, movable in between the two plugs and in connection with a plunger pin that engages one of the balls. There is also a two-way valve form.
