| 20110025439 | ACTUATING MAGNET - An actuating magnet is provided for a magnetic valve for a nonmagnetic pressure pipe, that is connected to at least one pole body, in which an armature is developed, and onto which at least two annular sleeves, having a ring lying between them, are slipped, in whose area a gap is situated that is developed between the armature and the pole body. Thereby, the actuating magnet may be developed in a simple manner by slipping annular sleeves and separating rings onto the pressure pipe. | 02-03-2011 |
| 20110248805 | LINEAR SOLENOID - A linear solenoid includes a shaft to reciprocate in an axis direction, a movable member fixed to the shaft, a front stator, a rear stator, a coil, a front housing, and a rear housing. The front housing is made of metal, and covers the front stator and the coil in the axis direction. The rear housing is made of metal, and is connected to the front housing so as to define a space to accommodate the movable member, the front stator, the rear stator and the coil. The rear housing covers the rear stator and the coil in the axis direction. | 10-13-2011 |
| 20120154079 | LINEAR SOLENOID - A linear solenoid includes a coil assembly having a coil, and a cup-shaped yoke arranged at an outer peripheral side of the coil. The yoke is provided with a recess portion that is opened at least at a position in a circumferential direction of the yoke and extends in an axial direction of the yoke. The coil assembly includes a connector portion that has a terminal connected to an exterior and is exposed from the recess portion to an exterior of the yoke, and a secondary molding portion made of a secondary molding resin in which the coil is insert-molded. Furthermore, the secondary molding portion includes a cover portion that is arranged to cover the recess portion of the yoke from an outer peripheral side of the recess portion. Thus, the cover portion can restrict foreign-material mixed oil from being introduced into the yoke. | 06-21-2012 |
| 20120154080 | SOLENOID WITH A TUBE - The invention refers to a solenoid, comprising a casing. The casing houses a coil body. The coil body supports windings of electrically conducting wire. The coil body surrounds an armature housing containing an armature. The casing wall of the casing has a recess in the area of the armature housing. Between the coil body and the armature housing a tube separated from the casing is arranged. The tube is joined to the inside of the casing wall facing the coil body without roundings. | 06-21-2012 |
| 20120299673 | SOLENOID HOUSING AND METHOD OF PROVIDING A SOLENOID HOUSING - This invention relates to a solenoid housing and to a method for providing a solenoid housing having the base, wall, center pole, and flange integrally connected as a single piece. The instant invention provides for mounting protrusions and window for electrical leads as an integral part of the housing and manufacturing process. | 11-29-2012 |
| 20130113583 | PROTECTED POWDER METAL STATOR CORE AND SOLENOID ACTUATOR USING SAME - A solenoid actuator includes a stator assembly with a stator core of formed powder metal received in a stator housing. A ferromagnetic protective sleeve is in contact with and covers a majority of an inner end face and a cylindrical wall of the stator core, while a flux ring is in contact with and covers an outer end face of the stator core. An armature assembly includes an armature attached to a stem that is movable in an air gap relative to the ferromagnetic protective sleeve. A spring is operably positioned in the ferromagnetic protective sleeve but electrically isolated from the stator housing. The stator core is encapsulated to protect against erosion and fragmentation. A magnetic flux line around a solenoid coil passes through the stator core, the ferromagnetic protective sleeve, the armature, the flux ring and back to the stator core. | 05-09-2013 |
| 20130234816 | Solenoid With A Plug-in And Turn Fastening - A proportionally acting solenoid with a plastics encapsulation having a fastening flange which is integrally formed thereon and contains shaped elements which permit installation of the solenoid onto the housing by axial pressing in, rotation and rotary latching, the shaped elements, in interaction with metallic springs and shaped elements of the housing, holding the solenoid on a housing axially and against rotation, and the springs being tensioned upon rotation of the housing during the installation, and the seal which seals the radial gap between the solenoid and the housing being coordinated, by means of the configuration thereof, with a small axial installation force. | 09-12-2013 |
| 20140111295 | SOLENOID HOUSING AND METHOD OF MAKING THE SAME - The invention relates to a solenoid housing fabricated by a method which allows a manufacturer to produce a high performing product while minimizing manufacturing complexity and time. The instant invention uses cold-forging techniques to reduce the need for fine machining processes. | 04-24-2014 |
| 20150310974 | SOLENOID COIL FOR HAZARDOUS LOCATIONS - A solenoid coil assembly for hazardous environments comprises a solenoid coil and an enclosure entirely filled with encapsulation material. The encapsulation material leaves zero or almost zero volume in the enclosure for hazardous material to accumulate in any amount that could explode. This allows the solenoid coil assembly to be constructed without the usual industry standard flame paths. Additionally, the enclosure may be made of physically rigid and strong material such as metal or the like to better withstand harsh and corrosive conditions within hazardous environments without being explosion proof. The walls of such an enclosure need only have a moderate thickness and weight relative to enclosures that are explosion proof, as there is no meaningful risk of an explosion occurring within the enclosure. The combination of a rugged exterior and a zero-volume interior allows the solenoid coil assembly to reduce weight and cost while providing superior environmental protection. | 10-29-2015 |
| 20150332828 | ELECTROMAGNETIC COIL, METHOD OF MANUFACTURING ELECTROMAGNETIC COIL, AND ELECTROMAGNETIC ACTUATOR - An electromagnetic coil includes a conductor winding | 11-19-2015 |
