A solenoid valve system includes a valve body defining porting for a fluid flow through the valve body, and first and second solenoid valve components attached oppositely to the valve body. Each valve component includes an electromagnetically driven armature with a poppet that moves between a closed position and an open position. The porting defined by the valve body includes first side porting, second side porting, and common porting in fluid communication with an internal common chamber defined by the valve body. When a respective poppet is in the closed position, flow of fluid is blocked between the respective side porting and the common porting, and when the respective poppet is in the open position the poppet permits a flow of fluid between the respective side porting and the common porting through the common chamber. Such configuration enhances carryover performance (reduces carryover time) while maintaining a compact footprint.

A solenoid valve includes a housing, a bobbin and an armature. The bobbin is received at least partially within the housing and has a body about which a coil is provided. A fluid flow path including an inlet and an outlet and a valve seat is defined by at least one of the housing or the bobbin, and the armature is moveable relative to the valve seat to control flow through the fluid flow path.

The plunger (108) is disposed at least partially within the guide (109). A housing (102) at least partially houses the frame (104), the coil (106), the guide (109) and the plunger (108), and the guide (109) is prevented from rotating independently of the housing (102).

A solenoid valve device may include a solenoid unit including a rod pin movable; a cylindrical core arranged around the rod pin; a bobbin covering a side surface of the cylindrical core; a coil wound around the bobbin; and a case having a bottom and being cylindrical, having an opening portion at one axial end, and arranged to accommodate the rod pin, the cylindrical core, the bobbin, and the coil; and a nozzle unit. The nozzle unit may include a nozzle having a pin receiving portion and a port opening portion; a first port and a second port; a valve body arranged in the nozzle; and a first metal member fixed to an end portion of the nozzle. The solenoid unit may include a positioning contact portion; and the case may include a fixing portion to fix the first metal member between the positioning contact portion and the fixing portion.

A high pressure valve includes a body on which is fixed an electromagnet, the shell of which has a radial discal part provided with a central hole connecting an internal opposite surface to an external surface. The body is provided with a cylindrical external centring surface and with a radial support surface. The shell is arranged on the body around the centring surface, the external discal surface being in surface contact against the support surface of the body. The coil of the electromagnet is arranged in the tubular space between the body and the shell itself closed by a closure ring. The liquid-tightness between the body and the shell is ensured by a gasket compressed by a wedging washer against the centring surface and against the internal discal surface. The shell is then immobilized on the body by the wedging washer.

A flow control device is disclosed. The flow control device includes a solenoid, the solenoid including an armature. Also, a piston connected to the armature. The piston includes a primary orifice. The piston having an open position and a closed position. A piston spring connected to the piston is also includes and at least one secondary orifice. The movement of the piston to the open position at least partially opens the at least one secondary orifice and the movement of the piston to the closed position at least partially closes the at least one secondary orifice. The movement of the armature actuates the piston movement and controls fluid flow from the primary orifice through the at least one secondary orifice.

Provided is an electromagnetic water supply valve including: a valve body including an upper member divided into upper and lower portions, a lower member configured such that water inlet and outlet are provided at the lower portion thereof and hooks are provided on an upper surface thereof, and a diaphragm horizontally disposed between the upper and lower members and resiliently mounted in the valve body by using a restorative element; an electromagnet unit being provided on the valve body, and including a bobbin and a yoke; and a plunger being provided between the valve body and the electromagnet unit by penetrating therethrough in an axial direction thereof and operating in conjunction with the diaphragm, so as to be magnetically moved up and down by a magnetic force generated by the bobbin in response to electrical control signals, thereby controlling water supply for an appliance.
