Abstract
A dual poppet low leak variable bleed solenoid valve, including a solenoid portion with an adjustable end cap disposed through the solenoid. Exhaust ports are disposed about the end cap. A hydraulic portion has a valve housing that is connectable to the solenoid portion. The hydraulic portion has a control volume formed within, and a supply port is connected through the valve housing. A valve shaft is slidably disposed through the solenoid portion and extends longitudinally into the hydraulic portion. A first end of the valve shaft terminates in the solenoid portion forming a primary valve, and a second end of the valve shaft terminates in the hydraulic portion forming a secondary valve. The valve shaft further has a hollow channel disposed through the valve shaft to allow the passage of a fluid medium between the first end and second end of the valve shaft.
