Abstract
A two stage solenoid actuated valve and method of actuation within a predetermined time interval. The valve provides fluid flow having a predetermined flow profile for displacement of a mass through a particular distance with a minimization of shock applied to the mass. The valve has a first and second stage in fluid communication each with the other. The first stage includes a solenoid valve and associated plug member for opening or closing flow through the first stage. The second stage includes a plug member having a predetermined contour head insertable within an orifice whose movement is responsive to the flow state of the first stage.
