Abstract

In an electromagnetically operated valve, the armature of a solenoid is arranged in substantial alignment with a valve seat surrounding a channel. The valve seat has a substantially planar surface. A valve member also having a substantially planar surface is provided to sealingly engage the planar surface of the valve seat. The armature of the solenoid has a spherical end face engaging the annular valve member.
