Abstract: A solenoid valve (10) includes a solenoid portion (24b) and a hydraulic portion (24a) having a valve housing (26) connectable to the solenoid portion (24b). A valve shaft (34) mounted in the housing (26) includes a first end positioned in the solenoid portion (24b) and a second end positioned in the hydraulic portion (24a). The valve shaft (34) includes a passage (36) disposed therethrough to allow fluid flow through the valve shaft (34). A valve (38) is located at the first end of the valve shaft (34). When the valve shaft (34) is moved in a first direction, the valve (38) moves toward a closed position, and when the valve shaft (34) is moved in a second direction, the valve (38) moves toward an open position.

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.
