Abstract
The electromagnetically operated valve includes a valve body, a plunger member, electromagnetic driving means for driving the plunger member along a flow direction inside the valve body into at least an open position in which a fluid is allowed to flow through the valve body and into a closed position in which the fluid is not, wherein the plunger member is arranged to be forced by a pressure of flowing fluid into the closed position, and to be driven by the electromagnetic driving means into the open position.
Claims10
An electromagnetically operated valve comprising:
- a valve body;
- a plunger member disposed inside the valve body, and adapted to move between an open position to facilitate fluid flow through the valve body and a closed position to prevent fluid flow through the valve body;
- an opening spring arranged inside the valve body that produces a spring force that biases the plunger member toward the open position and against a fluid force produced by a pressure of the fluid;
- and
- an electromagnetic driving means adapted to drive the plunger member toward the open position wherein the plunger member is arranged to be forced by a pressure of flowing fluid into the closed position, wherein the electromagnetic driving means includes a ferromagnetic ring and a coil surrounding the ferromagnetic ring which in turn is arranged surrounding the plunger member for generating an electromagnetic field causing a magnetic force suitable for biasing the plunger member toward the open position, and wherein the magnetic force plus the spring force is greater than the fluid force.
A fluid ejection system comprising:
- a fluid duct adapted to flow a fluid, the fluid duct having a duct inlet for receiving the fluid from a fluid source, and a duct outlet for discharging the fluid to the outside;
- an electromagnetically operated valve adapted to regulate the flow of the fluid through the fluid duct, the electromagnetically operated valve including;
- a valve body,
- a plunger member disposed inside the valve body, and adapted to move between an open position to facilitate fluid flow through the valve body and a closed position to prevent fluid flow through the valve body,
- an opening spring arranged inside the valve body that produces a spring force that biases the plunger member toward the open position and against a fluid force produced by a pressure of the fluid, and
- an electromagnetic driving means adapted to drive the plunger member toward the open position, wherein the plunger member is arranged to be forced by a pressure of flowing fluid into the closed position, wherein the electromagnetic driving means includes a ferromagnetic ring and a coil surrounding the ferromagnetic ring which in turn is arranged surrounding the plunger member for generating an electromagnetic field causing a magnetic force suitable for biasing the plunger member toward the open position, and wherein the magnetic force plus the spring force is greater than the fluid force;
- and
- an electronic control means configured to control electric power supplied to the electromagnetic driving means, wherein the amount of electric power supplied is based at least in-part on fluid pressure.
