Abstract
A relief valve comprises a stationary valve seat and a poppet member which has a valve surface sealingly engageable with the stationary valve seat. The poppet member has an axially extending wall in the vicinity of the valve surface. When the poppet valve is displaced from the stationary valve seat, the low pressure which is exerted against the poppet valve in the vicinity of the poppet valve surface resulting from fluid flowing between the stationary valve seat and the poppet valve surface is generally substantially exerted in a radial direction against the axial wall to thereby prevent reseating of the poppet member at the initial opening conditions for the relief valve.
