摘要： An electromagnetic proportional flow control valve includes an electromagnetic solenoid having a bobbin with an axial bore and a fixed core in the axial bore. A valve housing defines a first port, a second port and a valve seat fludically positioned between the first and second ports, while a valve is normally in a closing position for closing the valve seat and interrupting fluid communication between the first and second ports. A movable core is fixed to the valve and positioned relative to the electromagnetic solenoid such that the movable core is attracted to the fixed core upon excitation of the electromagnetic solenoid. As a result, the valve may move from the closing position upon excitation of the electromagnetic solenoid to fluidically communicate the first and second ports. An annular diaphragm is positioned between the valve and the electromagnetic solenoid and is sealingly mounted to the movable core so as to form a fluid tight pressure chamber on a side of the diaphragm opposite the valve. A passage in the movable core fluidically communicates the pressure chamber with the second port so that forces acting on the valve due to pressure differences across the valve are cancelled.

摘要翻译： 电磁比例流量控制阀包括电磁螺线管，该电磁螺线管具有轴向孔的筒管和轴向孔中的固定芯。 阀壳体限定第一端口，第二端口和位于第一和第二端口之间的阀座，同时阀通常处于关闭位置以关闭阀座并中断第一和第二端口之间的流体连通。 可动铁心固定在阀门上并相对于电磁螺线管定位，使得可动铁芯在电磁螺线管激励时被吸引到固定铁芯上。 结果，当电磁螺线管激励时，阀可以从关闭位置移动，以流体地连通第一和第二端口。 环形隔膜位于阀和电磁螺线管之间，并且密封地安装到可动铁芯上，以便在隔膜的与阀相对的一侧上形成流体密封的压力室。 可动芯体中的通道使​​压力室与第二端口流体连通，从而消除由于阀门两端的压力差而作用在阀门上的力。

摘要： A solenoid valve comprises a housing including an inlet port for fluid communication with a positive pressure source and an outlet port for fluid communication with a negative pressure source; a passage for fluid communication between the inlet port and the outlet port; and an axially bi-directional solenoid-actuated valve in the housing for opening and closing the passage, including an electromagnetically movable valve member having a sealing area exposed to the negative pressure from the outlet port when the valve means is in the closed position; and a diaphragm defining a back pressure chamber in fluid communication with the passage for offsetting the effect of the negative pressure on the exposed sealing area and reducing the electromagnetic force required to move the valve member.

摘要： A Stirling cycle type engine having five cylinders annularly and equiangularly arranged is disclosed. The expansion chamber of one cylinder is connected to the compression chamber of an adjacent cylinder through a cooler device, a regenerator, and a heater device. The cooler device, regenerator, and heater device are serially stacked and are contained within a cylindrical element. The five cylinders and five cylindrical elements which function as heat exchanging means are supported by a frame having a plurality of plate elements. Each heater device is placed on one of the plate elements adjacent the expansion chamber of one of the cylinders.

摘要： An electrically operated fluid control valve unit is associated with a moving-coil linear motor which includes the quantity of fluid flow across the tubular core, a permanent magnet for providing magnetic flux through the tubular core, a permanent magnet for providing magnetic flux through the tubular core, a moving-coil wound on the bobbin across the magnetic flux of the magnet to provide a linear force on the bobbin, and a pair of conductive springs connecting the moving-coil to an electric control circuit and biasing the bobbin toward its initial position. Each of the springs is insulated from one another and from the valve housing, the tubular core and the like to prevent from unexpected short of the springs.
