Abstract
A valve assembly is disclosed, which includes a valve body defining a valve chamber and a moveable member. The moveable member has a valve element at its first end and an armature at its second end. The moveable member is moveable in an axial direction to selectively open and close the valve. The entire moveable member is spaced from the walls of the valve body when the valve is open or partially open. A flexible membrane forms a seal against the moveable member and the valve body to divide the valve chamber into a flow chamber in which the valve seat and valve element are located and a pressure compensation chamber within which the armature is entirely enclosed. A first fluid port is fluidly connected to the pressure compensation chamber via one or more bores in a pressure compensation flow path with at least one opening extending into the pressure compensation chamber at an axial position between the armature and the flexible membrane. The pressure compensation flow path includes a first axial portion with a first cross-sectional area and a second axial portion with a second, smaller cross-sectional area.
