摘要： The invention relates to a proportional control pressure valve which is used as relay valve or directional control valve. Said proportional pressure control valve is provided with a pressure reducing function and a pressure back-up function and essentially consists of a valve housing (2) with inlets and outlets (4, 5, 6), a control element (7), an anchor bar (8) and a proportional magnet (3) that consists of a magnet core (10), a magnet anchor (11) and a magnet coil (12). The proportional magnet (3) has an almost constant magnetic power in its working area. According to the invention, the smallest axial distance (13) between the magnet anchor (11) and the magnet core (10) is measured in a holding position of the magnet anchor (11) in such a way that the magnetic power between said two components (10, 11) is greater in the holding position than the magnetic power in the working area of the proportional magnet (3) and that the magnet anchor (11) can be fixed in the holding position by the magnetic power.

摘要： A latching electromagnet is provided. The electromagnet (300) includes a core (305) having a pole face, a coil of windings (325), and an armature (330). Advantageously, the core has a geometry that locally increases the magnetic flux density to saturation levels.

摘要： An electromagnetically actuator (10) is disclosed having an electromagnet (12), a core element (16), the core element having a normally biased initial spaced apart first position distal from the electromagnet when the electromagnet is off and a second stop position proximal from the electromagnet when the electromagnet is on, a first resilient member (20) adapted to bias said core element in the normally biased first position, and a second resilient member (50) adapted to bias the electromagnet away from the core. The first resilient member is more resilient than the second resilient member. Therefore, the core approaches the electromagnet when the electromagnet is on until the core reaches the fixed stop position, and the electromagnet subsequently approaches the core to the fixed stop position. The actuator may further include an adjustment member (60) that engages the electromagnet so as to control the pressure of the electromagnet against the second resilient member, whereby the axial position of the electromagnet is controlled.

摘要： An inexpensive linear solenoid actuator for moving a plunger (50, 56, 58) along a straight line, while providing a force on the plunger due to the solenoid (32) which does not vary greatly over the length of stroke of the plunger; a spring (82) opposes the force exerted on the plunger by the solenoid, so that the plunger will assume any of a range of positions in response to different currents through the solenoid. The plunger has a first larger portion (50) of magnetic material sliding in a first bearing (48); a tapered second magnetic portion (56) extending forwardly from the first portion; a magnetic third portion (58) of substantially cylindrical form extending forwardly from the tapered portion; and a fourth non-magnetic portion (64) sliding in a second bearing (46) and supporting the front end of the plunger. The second bearing (46) is in a magnetic end piece (40) having substantial axial width. The stroke of the plunger is preferably such that the forward end of the magnetic third portion moves from a first position near the adjacent end of a magnetic end piece (40) in which the second bearing (46) is mounted, to a second position well within or outside the other end of the magnetic end piece (40). The actuator (110) may be built into the casing (101) of the fuel pump, with trapped air in and around the solenoid preventing contamination of the actuator by fuel oil (118) in the casing.

摘要： An attraction blade plate is disposed on a plunger of a plunger type electromagnet to improve the shape of the plunger and the shape of a fixed core, or a cylinder equipped with a single flange and made of a magnetic material is fitted to the axial-direction end portion of a coil bobbin. According to each technical means, the change rate of permeance of a magnetic path at the time of attraction can be made great and high sensitivity of the electromagnet can be accomplished. Attraction retention force is controlled by adjusting the area of the contact surface between the fixed core and a movable core. A permanent magnet is shaped in a toroidal shape and the direction of magnetization is formed in the direction of the thickness of the toroidal shape. Accordingly, magnetization of the permanent magnet becomes easier and the number of components can be reduced. In this manner, a compact and light-weight electromagnet can be mass-produced.

摘要： An electromagnetically operated valve assembly for use in an internal combustion engine includes a valve (2), serving as an intake or exhaust valve, made of a ceramic material for reduced weight and good response in operation. The valve assembly also includes an electromagnetic actuator comprising a movable member (22) mounted on the upper end of the valve stem (23) of the valve and having a frustoconical flange (222) portion on an end thereof. A fixed member (41) is disposed above the movable member in confronting relation thereto and has a recessed portion (412) complementary in shape to the frustoconical flange portion. With this arrangement, while the valve is made of a nonmagnetic ceramic material, a sufficient magnetic path cross-sectional area is maintained through the movable member without increasing the size of the movable member.

摘要： A proportional solenoid has a fixed pole piece (39) and a movable armature (45), both fitted into the bore (52) of a guide tube (36) that provides the required concentricity between the fixed and movable pole pieces (39) and (45). One of the pole pieces has a cylindrical recess (56) and the other pole piece has a reduced diameter cylindrical nose (62) that is complementary to cylindrical recess (56). A radially inwardly facing frusto-conical surface (95) is formed in cylindrical nose (62) to be disposed within recess (56) of the other pole piece and provide a frusto-conical pole piece section producing a linear force-stroke curve.
