ABSTRACT:
A direct-operated, two-way solenoid valve is disclosed. The valve balances the hydraulic flow forces acting on a poppet in order to achieve fast-acting, high-flow operation. The valve has a housing with the poppet mounted in a main bore. The poppet has a sealing end with a longitudinal central bore that is open at the sealing end and terminates in a pressure wall. A radial cross bore in the poppet provides fluid communication between the central bore and an outlet port formed in the housing. The sealing end of the poppet may contact a valve seat to prevent fluid communication between an inlet port formed in the housing and the central bore of the poppet. The sealing end of the poppet is biased into contact with the valve seat to prevent fluid communication between the inlet port and the central bore. An actuator generating a magnetic flux path tends to move the poppet out of contact with the valve seat.
