Abstract
A solenoid assembly for use in connection with a housing and valve body is provided. The assembly includes a magnetic coil, a magnetic pole piece, an operating rod, a magnetic armature, and at least two bearings positioned between a portion of the magnetic pole piece and a portion of the operating rod. The operating rod is slidably disposed along the bearings. The magnetic armature is at least in part centered relative to the pole piece. Activation of the coil provides an attraction between the armature and the pole piece.

A solenoid assembly for use in connection with a housing and valve body, the assembly comprising:
- a magnetic coil;
- a magnetic pole piece, at least a portion of the pole piece positioned inside of the coil;
- an operating rod positioned within a portion of a cavity or aperture formed by the pole piece;
- a magnetic armature positioned about an end of the operating rod, the armature configured to interact directly with said housing;
- and
- at least two bearing positioned between a portion of the magnetic pole piece and a portion of the operating rod;
- wherein the operating rod is slidably disposed along the bearings, the armature is at least in part centered relative to the pole piece, and activation of the coil provides an attraction between the armature and the pole piece.
A solenoid assembly for use in connection with a housing, the assembly comprising:
- a magnetic coil;
- a magnetic pole piece, at least a portion of the pole piece positioned inside the coil;
- an operating rod comprised of a non-magnetic material that is positioned within a portion of a cavity or aperture formed by the magnetic pole piece;
- a magnetic armature positioned about one end of the operating rod, the armature configured to interact directly with said housing;
- and
- at least two bearings positioned between a portion of the magnetic pole piece and a portion of the operating rod;
- wherein the operating rod is slidably disposed on the bearings;
- the armature is at least in part centered relative to the pole piece;
- activation of the coil provides an attraction between the armature and the pole piece;
- the operating rod is retained on-center by the at least two bearings;
- and the activation of the coil attracts the armature to the pole piece.
A solenoid assembly for use in connection with a housing and valve body, the assembly comprising:
- a magnetic coil;
- a magnetic pole piece, at least a portion of the pole piece positioned inside of the coil;
- an operating rod positioned within at least a portion of a cavity or aperture formed by the pole piece;
- a magnetic armature positioned externally at an end of the operating rod;
- and
- at least two bearing positioned between a portion of the magnetic pole piece and a portion of the operating rod;
- wherein the operating rod is slidably disposed along the bearings and wherein at least a portion of the magnetic pole piece comprises the bearings or is configured to receive the bearings.
