摘要：The invention is a two-stage, two-poppet prime valve assembly for use in highpressure applications such as vehicle braking systems. The valve assembly has two valveseats and two plungers for allowing the valve assembly to open under high pressure

while providing minimal internal flow restrictions to enhance cold temperature and lowpressure operation. The two-stage, two poppet valve assembly contains two separateflow paths, one being high pressure, relatively low flow called a stage one, and the otherbeing relatively low pressure, high flow called a stage two. In addition, the valve

incorporates a reverse flow bypass feature that is capable of controlling flow at very highpressure and allowing reverse flow with a very low pressure drop.
