Diaphragm valve

A diaphragm valve, comprising:

• a solenoid body having a coil and a pole piece positioned in the solenoid body;
• a valve body cartridge connected to the solenoid body;
• an armature slidably disposed in the solenoid body for movement along a longitudinal axis between an energized position and a de-energized position, the armature including a biasing member seat that extends radially outwardly;
• a valve member slidably disposed in the valve body cartridge, the valve member connected to the armature for movement therewith;
• a biasing member extending around the armature that acts against the biasing member seat of the armature to normally bias the armature toward the de-energized position;
• a diaphragm extending radially inwardly from the valve body cartridge that is received between the armature and the valve member;
• and
• a diaphragm support sleeve having a support sleeve wall and a support sleeve flange, the support sleeve wall extending annularly about the biasing member and the support sleeve flange extending radially inwardly from the support sleeve wall such that the support sleeve flange abuts and supports at least part of the diaphragm, wherein the support sleeve flange extends radially inward of the biasing member seat of the armature.

A diaphragm valve, comprising:

• a manifold including a manifold bore;
• a valve body cartridge received in the manifold bore, the valve body cartridge including a valve seat;
• a solenoid body connected to the valve body cartridge, the solenoid body having a coil and a pole piece positioned in the solenoid body;
• an armature slidably disposed in the solenoid body for movement along a longitudinal axis between an energized position and a de-energized position;
• a valve member slidably disposed in the valve body cartridge, the valve member connected to the armature for movement therewith;
• a biasing member disposed in the solenoid body that acts to normally bias the armature toward the de-energized position;
• a diaphragm extending inwardly from the valve body cartridge that is received between the armature and the valve member such that the diaphragm deflects in response to movement of the armature and the valve member along the longitudinal axis;
• and
• a diaphragm support sleeve having a longitudinally extending support sleeve wall that defines a sleeve cavity and a transverse support sleeve flange that extends inwardly from the longitudinally extending support sleeve wall, wherein the sleeve cavity receives at least part of the armature, wherein the transverse support sleeve flange abuts and supports at least part of the diaphragm, wherein the diaphragm is clamped between the valve body cartridge and the diaphragm support sleeve.
