摘要： A single solenoid based double actuator device 100 is disclosed having a first actuator 106 configured for linear movement between actuated and dropped positions along an axis of a winding 102 and biased towards dropped position, and a second actuator 120 arranged spaced apart from the first actuator 106 for linear movement between actuated and dropped positions and biased towards dropped position. A pair of magnetic paths, an upper magnetic path 130, and a lower magnetic path 132, is provided at two ends of the actuators such that first actuator, upper plate 130, second actuator 120 and lower plate 132 provide a magnetic path for a magnetic field generated on passing a current through the winding 102. On passing a current exceeding a first current value, through the winding, one of the actuators is actuated, and on the current exceeding a second current value, other actuator is also actuated.

摘要： A power versatile and energy efficient electric coaxial valve is a dual magnetic latching electric tube-type valve having an electrically pulsed actuated permanent electromagnet with an armature having three active poles to increase the magnetic force of the armature provided by permanent magnets for energy efficiency. The electric coaxial valve is augmented with a balanced spring means that works in concert with the armature to increase the internal force and tube movement distance, while reducing the energy needed to operate the valve. The increased magnetic force, internal force, and tube movement distance provide a coaxial valve that can have increased pressure or flow area. The valve is power versatile in that the pulsed electric means used to operate the valve is power versatile.
