Abstract: A straight fluid flow solenoid valve 10 comprising a conduit 24 having an inlet 148, an outlet 146 and a seat 88 member therein with an aperture 90 therethrough; a plunger 68, backstop 76 and spring 70 positioned inside the conduit 24 such that when a voltage is impressed upon a coil 22 circumferentially positioned around the exterior of the conduit 24, the plunger 68 is moved from a closed position to an open position thereby allowing a fluid to pass through the solenoid valve 10 in a substantially laminar flow stream while engaging the plunger 68 and the backstop 76.
