    • A pressure balanced solenoid operated valve includes a solenoid portion having a coil in a coil retainer. A valve member portion defines a body connected to the solenoid portion. A slidable valve member in the body has opposed first and second ends and a shoulder between the ends. The first end with the coil energized is magnetically drawn toward the coil retainer moving the valve member between a valve closed and a valve open position. A pressure equalizing passage extends in the valve member from the second end. An inlet passage communicates a pressurized fluid at a valve inlet port to the pressure equalizing passage. A connecting passage communicates between the pressure equalizing passage and the shoulder. The pressurized fluid in the pressure equalizing passage acts against the second end and equally and oppositely against both the shoulder and the first end in both the open and closed positions.
    • 压力平衡电磁阀包括在线圈保持器中具有线圈的螺线管部分。 阀构件部分限定连接到螺线管部分的主体。 主体中的可滑动的阀构件具有相对的第一端和第二端以及端部之间的肩部。 线圈通电的第一端被磁力吸引到线圈保持器,以使阀构件在阀关闭和阀打开位置之间移动。 压力平衡通道在阀构件中从第二端延伸。 入口通道将阀入口处的加压流体连通到均压通道。 连接通道在压力平衡通道和肩部之间连通。 压力平衡通道中的加压流体在打开位置和关闭位置两者相对于肩部和第一端相对地抵靠第二端作用。

    • Various embodiments of a cardiac pacemaker device and methods are provided. In one embodiment a cardiac pacemaker device includes a pulse generator which emits a plurality of stimulation pulses such that each of the plurality of stimulation pulses is separated by a plurality of inter-beat durations, respectively. The pacemaker device further includes a pacing algorithm configured to implement the pulse generator to generate alternately shorter and longer inter-beat durations independent of hemodynamic loading conditions and such that the average inter-beat duration remains constant.
    • 提供心脏起搏器装置和方法的各种实施例。 在一个实施例中,心脏起搏器装置包括脉冲发生器,其发射多个刺激脉冲,使得多个刺激脉冲中的每一个分别由多个搏动间隔持续时间分开。 起搏器装置进一步包括起搏算法,该起搏算法被配置为实现脉冲发生器以产生与血流动力学负载条件无关的交替更短和更长的搏动间持续时间,并且使得平均搏动间持续时间保持恒定。
