Abstract
An electromagnetically actuated valve is disclosed. The valve includes an upper electromagnetic element and a lower electromagnetic element in a mirrored and facing relationship to each other. The electromagnetic elements define a central channel that surrounds a vertical axis. The valve further includes an armature element that is disposed intermediate the upper and lower electromagnets. The armature element is pivotally mounted to an armature shaft. The armature shaft is perpendicular to the vertical axis. The valve further includes a coil disposed within the central channel of each of the electromagnetic elements.
Claims5
An electromagnetically actuated valve comprising:
- an upper electromagnetic element and a lower electromagnetic element, each of said electromagnetic elements having a pole face, a central channel disposed in said pole face, a coil disposed in said channel and a cylindrical bore extending through each said electromagnetic element in said pole face in an area thereof within said central channel wherein said upper and lower electromagnetic elements are in a mirrored relationship to each other, said pole face of said upper electromagnetic element being in a facing relationship to said pole face of said lower electromagnetic element, said cylindrical bore of each of said electromagnetic elements being coaxially disposed along a vertical axis;
- an armature shaft, said armature shaft being perpendicular to and spaced from said vertical axis;
- an armature disposed intermediate said upper and lower electromagnetic elements said armature having an upper face in a facing relationship to said pole face of said upper electromagnetic element and being substantially mateable therewith when said armature is in a position adjacent said upper electromagnetic element, a lower face in a facing relationship to said pole face of said lower electromagnetic element and being substantially mateable therewith when said armature is in a position adjacent said lower electromagnetic element, a proximal end pivotally mounted to said armature shaft and a distal end generally displaceable along said vertical axis;
- an first valve shaft portion disposed in axial slideable engagement within said bore of said upper electromagnetic element extending outwardly therefrom and a second valve shaft portion disposed in axial slideable engagement within said bore of said lower electromagnetic element extending outwardly therefrom, each of said first valve shaft portion and said second valve shaft portion having a first end and a second end, said first end of said first valve shaft portion being in intimate slideable contact with said upper face of said armature at said distal end, said first end of said second valve shaft portion being in intimate slideable contact with said lower face of said armature at said distal end:
- a first spring connected to said second end of said first valve shaft portion and a second spring connected to said second end of said second valve shaft portion to return said armature to a position intermediate said upper electromagnetic element and said lower electromagnet element.
