Double acting permanent magnet latching solenoid

Abstract: A solenoid which is driven positively in both directions by reversal of coil current and held in place at either end by flux from a permanent magnet located at the center of the frame. The permanent magnet is formed of two opposed sections fitting tightly between the plunger tube and frame, and is located in a space between two coils. In one form the two magnet sections are formed of compressible material and are recessed to fit closely around the plunger tube.

Power feeder for solenoid valves

Abstract: A power feeder for solenoid valves has a printed wiring board carrying a printed feeder circuitry firmly supported on a manifold base. Thus, electrical connection between the solenoid valves and printed wiring board is accomplished simultaneously with the fastening of the solenoid valves to the manifold base. U-shaped brackets having a width corresponding to the width of each solenoid valve are attached to rails provided on one side of the manifold base by fitting engaging shoes provided on one side wall of the brackets over the rails. The printed wiring board is placed on the side walls of the brackets, while the feeding terminal of a terminal box at one end of the connected brackets is connected to the receiving terminal of the printed wiring board by means of a cable connector passed through the brackets. Feeding terminals corresponding to the receiving terminals of the solenoid valves are provided on the printed wiring board so that the feeding terminals on the printed wiring board are directly connected to the receiving terminals of the solenoid valves as the solenoid valves are mounted on the manifold base. This arrangement provides firm support to the printed wiring board, assures easy and sure solenoid valve mounting and feeder terminal connection. Also, the printed wiring board is covered with the brackets and base plates that afford adequate protection from the workshop environment that might be unfavorable.

Fuel injection valve

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of easily changing spray angle of fuel according to operation conditions of an internal combustion engine SOLUTION: This valve is provided with a first swirl adding passage 21 formed to connect to an injection hole of a fuel injection valve main body with extending in a tangential direction of a tip part outer circumference 5a of a needle valve 5, a second swirl adding passage 23 formed to connecting to an injection hole of the fuel injection valve main body with extending toward a center part 5c side of the needle valve 5 than the tangential direction of the tip part outer circumference 5a of the needle valve 5, a solenoid valve opening and closing the first fuel supply route including the first swirl adding passage 21, and a solenoid valve opening and closing the second fuel supply route including the second swirl adding passage 23 Spray angle of fuel injection is regulated by opening and closing the two solenoid valves respectively according to operation conditions of the internal combustion engine and circulating fuel to one or both of the first swirl adding passage 21 and the second swirl adding passage 23 COPYRIGHT: (C)2006,JPO&NCIPI

Test of the ITER TF insert and Central Solenoid Model Coil

Abstract: The Central Solenoid Model Coil (CSMC) was designed and built by ITER collaboration between the European Union, Japan, Russian Federation and the United States in 1993-2001. Three heavily instrumented insert coils have been also built for testing in the background field of the CSMC to cover a wide operational space. The TF Insert was designed and built by the Russian Federation to simulate the conductor performance under the ITER TF coil conditions. The TF Insert Coil was tested in the CSMC Test Facility at the Japan Atomic Energy Research Institute, Naka, Japan in September-October 2001. Some measurements were performed also on the CSMC to study effects of electromagnetic and cooldown cycles. The TF Insert coil was charged successfully, without training, in the background field of the CSMC to the design current of 46 kA at 13 T peak field. The TF Insert met or exceeded all design objectives, however some interesting results require thorough analyses. This paper presents the overview of main results of the testing - magnet critical parameters, joint performance, effect of cycles on performance, quench and some results of the post-test analysis.

Solenoid operated clutch for powered sliding door

Abstract: A clutch (10) (e.g. for a powered sliding door) comprises a gear (24) axially shiftable from a disengaged position to an engaged position by a solenoid (58) actuated reciprocating means (56) counteracting a biasing means (38).
