Title: Solenoid valve with main and auxiliary valve plug - opposing pole of latter slides in plug guide
Inventor: OFFENWANGER WOLFGANG
IPC: F16K31/40
Filed: 1974-08-16
Abstract: Previous designs of similar arrangements worked on the principle that the magnitude of the lift of the main valve plug was dependent on the lift of the armature and/or the auxiliary plug. Instead, a movable arrangement sliding inside the plug guide acts as the opposing pole, or alternately the main valve plug serves as an opposing pole for the armature, which is spring loaded and can slide against the main valve plug. The opposing pole can be an integral part of the main valve plug or arranged separately. A distancing pin can be arranged between the main valve plug and the opposing pole.
