Abstract
A poppet valve for controlling water flow is provided, the poppet valve includes a housing, a movable armature arranged within the housing, a pilot pin having first and second ends, and a return element associated with the pilot pin. The first end of the pilot pin is associated with and driven by the armature, and a poppet is arranged around the second end of the pilot pin. A cage is arranged around the poppet, the cage having a transverse opening adapted for water to flow therethrough. The armature is selectively actuated to drive the pilot pin in a first direction towards a closed position, in which the transverse opening of the cage is blocked by the poppet. The return element drives the pilot pin in a second direction towards an open position, in which the transverse opening of the cage is unblocked by the poppet.
