Abstract
An electromechanical valve actuator including an electromagnet interconnected with a housing end portion and an electric coil disposed adjacent said electromagnet. The electromagnet includes a plurality of interlocked laminae to form a laminate that is similarly interlocked with housing end portions. The housing end portions are interlocked with the laminate with the use of tabs and recesses formed on the laminae and the housing end portions.
Claims15
An electromechanical valve actuator comprising:
- an electromagnet including a plurality of interlocked laminae, at least one of said laminae having a tab;
- a housing end portion having a recess formed for matingly receiving said tab for interlocking said housing end portion to said plurality of interlocked laminae;
- and
- an electric coil disposed adjacent said electromagnet.
An electromechanical valve actuator comprising:
- an electromagnet including a plurality of interlocked laminae, at least one of said laminae having a slot;
- a housing end portion having a stake formed for being matingly received in said slot for interlocking said housing end portion to said plurality of interlocked laminae;
- and
- an electric coil disposed adjacent said electromagnet.
An electromagnet assembly for an electromechanical valve actuator comprising:
- an armature electromagnet including a plurality of armature laminae interlocked to form a armature laminate and interlocked with armature housing end portions;
- and
- a valve electromagnet including a plurality of valve laminae interlocked to form a valve laminate and interlocked with valve housing end portions.
A method of forming an electromagnet for use in connection with an electromechanical valve actuator comprising:
- stamping electromagnet sheet stock material to form a laminae;
- stamping a plurality of tabs having a recess in each of said laminae for interlocking a plurality of said laminae together;
- aligning each of said laminae together along an axis defined by said tabs;
- pressing each of said aligned laminae together to cause said laminae to interlock at each of said tabs to thereby form a laminate;
- aligning a recess of a housing end portion along said axis;
- and
- connecting said laminate to said housing end portion by interlocking at least one of said tabs into said recess of said housing end portion.
