Patent ID: 10473229

Abstract:
A diaphragm valve includes a solenoid body having a coil and a pole piece. An armature is configured to slide in the solenoid body along a longitudinal axis between energized and de-energized positions. A valve body cartridge is connected to the solenoid body. A valve member, connected to the armature, is configured to slide within the valve body cartridge when the armature moves. A biasing member acts to normally bias the armature toward the de-energized position. A diaphragm, extending inwardly from the valve body cartridge towards the valve body, is received between the armature and the valve member. A diaphragm support sleeve includes a support sleeve wall defining a sleeve cavity that receives the armature and a support sleeve flange that extends inwardly from the support sleeve wall to abut and support at least part of the diaphragm.
