Abstract
A single stage solenoid operated valve assembly of the cartridge type having a reversing flow orifice assembly with a side port, bottom port and an orifice. A poppet is adapted to seat in and close the orifice for controlling fluid flow between the side and bottom ports. A transverse flow passage provides fluid communication between the side port and the orifice and a pair of longitudinal flow passages provide fluid communication between the bottom port and a chamber above the poppet. An axis normal to the longitudinal axis of both longitudinal flow passages is also normal to the axis of the transverse flow passage. In this way pressure over the poppet is provided when fluid pressure is applied to the bottom port and pressure under the poppet is provided when fluid pressure is applied to the side port.
