摘要： An electromagnetic actuator (10) is disclosed having a ferromagnetic case (12) and defining a central axis with a slidable core (16) disposed coaxial with the central axis. The core includes first end (20), second end (22) and core (24) portions. The actuator (10) further includes a magnetic flux developing element (18) mounted coaxial with the central axis and first and second ferromagnetic electrical coils (14). The first and second coils (14) are mounted in a facing relationship with the first (20) and second (22) end portions of the core (16). The coils (14) have a cross-sectional length in a direction perpendicular to the central axis and a width of insulating space between the turns of the coils (14) in a direction parallel to the central axis. The length and width are selected such that the reluctance of the width of the insulating space is greater than the reluctance of the cross-sectional length of the coil wire adjacent the insulating space.

摘要： An electromagnetically actuated valve (10) is disclosed having an upper electromagnetic element (32) and a lower electromagnetic element (34), each having a toroidal or annular configuration with a U-shaped cross section and in mirrored relationship with each other. The elements define a central chamber (26) and a central channel (30). A core element (16) has an annular horizontal cross section and is disposed intermediate the upper (32) and lower (34) electromagnetic elements. A connecting plate (18) connects the core element (16) to a valve stem (22). A spring (20) biases the core element (16) to a neutral position. Applying current to the upper electromagnetic element (32) closes the valve and interrupting the current to the upper electromagnetic element (32) and applying current to the lower electromagnetic element (34) opens the valve.

摘要： An improved electromagnetically actuated valve (10) is disclosed. The improved valve design includes a layer of structurally stable, non-magnetic material (52), preferably Kapton or Chrome, disposed intermediate the core element (16) and the electromagnetic element (32, 34) of the valve, and a core element and electromagnetic element fabricated from a high electrical resistive iron material. The layer of non-magnetic structurally stable material and high resistance core element serve to eliminate the hysteresis effect in the magnetic force of the valve. The core element may also include radially extending (50) or axially extending (48) perforations through the core element. The axial and radial perforations serve to reduce the weight of the core design and the axial perforations serve to reduce the effect of the air spring created in the gap as the core element approaches the electromagnetic element during operation of the valve.

摘要： An electromagnetically actuated valve (10) includes an upper electromagnetic element (24) and a lower electromagnetic element (26) in a mirrored and facing relationship to each other. The electromagnetic elements (24, 26) define a central channel (20) that surrounds a vertical axis (22). The valve further includes an armature element (16) that is disposed intermediate the upper and lower electromagnetic elements (24, 26). The armature element (16) is pivotally mounted to an armature shaft (32). The armature shaft (32) is perpendicular to the vertical axis (22). The valve further includes a coil (14) disposed within the central channel (20) of each of the electromagnetic elements (24, 26).

摘要： Compressor (50) includes electromagnetic element (76), core (77), coil (80), armature (78) and piston (58), controlled by electromagnetically actuated valve (52). Surface (104) has continuous channel (90) around opening (88). The channel has a top portion (106) of frustoconical cross section, and coil (80) in bottom portion (108). The armature has raised portion (110) to be received in top portion (106). Valve shaft (56) lies in the opening of the electromagnetic element and is connected to the armature. The compressor piston is connected to one end of the shaft. Support spring (84) lies in the opening of the electromagnetic element, and extends from the retaining bar (82) to the upper surface of the cylinder. Two lower springs (86) extend from the armature to a lower support surface and bias the armature in a normally spaced-apart relationship from the electromagnetic element. Applying current in the coil causes the piston to move upward, and interrupting the current causes the piston to move downward.
