摘要： An improved solenoid for use in a solenoid actuated valve or switch as disclosed. The problem with the prior art solenoid is that the magnetic circuit thereof during operation of the solenoid contains two air gaps which adversely affect not only the pulling force of the solenoid but also its response time. The pulling force and response time is improved by the incorporation of a plate or disc type armature (68, 90, 154) which is relatively unrestrained with respect to the actuating mechanism for the valve or switch device to be operated thereby to eliminate one of the air gaps leaving thereby only a single air gap in the magnetic circuit (Fig. 2).

摘要： In a clapper type contactor (10) having a magnetic latch (20) which retards the movement of the armature until the magnetic force builds to a level that will carry the armature through its complete motion without hesitation Often times in the past, clapper type contactors would have their armatures move prematurely before the magnetic force builds to a level that will carry the armature through its complete motion without hesitation. Contactors including an auxiliary arm spring as well as a closing spring are especially prone to this condition with worn contact tips. The magnetic latch circuit described herein eliminates the foregoing problem by retarding the armature movement until the magnetic force builds to a level that will carry the armature through its complete motion without hesitation. The magnetic latch circuit includes the core (14) of an electromagnetic coil (12), a magnet frame (16) upon which the core and coil are mounted, a magnetic latch (20) having a stop surface (52) resting upon the magnetic frame (16) and a pair of ears (50) extending up from the stop (52) for securing the magnetic latch (20) to a pivoted contact arm (22) and an armature (18) fixedly attached to the contact arm (22) and pivoted therewith adjacent one end of the latch plate and extending down from the contact arm, and an air gap between the armature (18) and the core (14) of the coil (12). These elements complete a flux path for the magnetic circuit. Shortly after the current begins to build in the coil upon energization of the same, the magnetic latch plate (20) goes into saturation and then an additional parallel flux path is established between the core, the magnetic frame, through the heel air gap of the armature, through the armature, and finally through the armature core air gap to complete the circuit.

摘要： The present invention relates to an rotary-segment electromechanical system and an electrical switching device comprising the same, which is capable of performing a direct rotating motion limited by a rotation angle of up to 45°, offering hereby a torque performance suitable for contact systems of electromechanical relays. The electromechanical system includes a pair of pole members having respective first end portions arranged outside respective first and second coils and a rotation member arranged between the pole members. The rotating member has a pair of lobes which can rotate around a central axis aligned along the intersection of a plane parallel to the first end portions with a plane transverse to the first coil axis under magnetic actuation exerted by the pole members. The pole members and rotating member are constructed with a reluctance-boost shape contour which enhances the actuating magnetic force onto the rotating member.
