  • Patent number: 9857440
    Abstract: A stable assembly of a metal detector is disclosed which can ensure a tension free physical connection between a former and a case of the metal detector. The metal detector includes a case with at least four closed sides and two openings, a non-conductive former having a pass-through aperture, and electromagnetic coils arranged on the former to produce an electromagnetic field within the former which is disturbed by a metallic body passing through the aperture. The former formed into a single piece and having a width equal to the inner width of the case, is inserted into the case from the front side of the case. The space between the former and the case is filled with a potting medium. The physical connection between the former and the case includes a protruding-recess which is strengthened by an adhesive.

  • Patent number: 8375973
    Abstract: A one-piece metal orifice tube (130) for use in a solenoid valve (100) is provided according to the invention. The one-piece, metal orifice tube includes a metal tube portion (131) including a proximal end (140) and a distal end (142), with the distal end being adapted to extend into an electromagnet bore (103) of an electromagnet (102) of the solenoid valve. The one-piece metal orifice tube further includes an orifice end (132) formed in the proximal end (140). The orifice end includes an orifice (133) that is smaller in diameter than a tube inside diameter D of the metal tube portion and the metal tube portion is adapted to slidably receive at least a portion of an armature (105) of a solenoid valve. In operation, the armature substantially blocks and unblocks the orifice.

  • Patent number: 8215611
    Abstract: A system and method for operating a solenoid valve is disclosed. The solenoid valve is operated by moving a first valve element (4) with respect to a second valve element (6, 7) a first distance. And then pulling the second valve element (6, 7) with the first valve element (4) a second distance where the second valve element (6, 7) moves against resistance from a seal (8) and where the movement of the second valve element (6, 7) opens a gap with respect to an orifice (10). The second element (6, 7) then moves a third distance under spring load to open an increased gap with respect to the orifice (10).
