    • A transmission vacuum modulator assembly has a vacuum modulator with a heavy-gauge spring and a diaphragm that are moveably linked to a sliding or spool valve in a bore in a valve assembly. The flow of hydraulic transmission fluid into the transmission, preferably a diesel automatic transmission, is regulated by the sliding valve. The improvement comprises adding a coil spring having a spring force of between about 1 and 2 p.s.i. to the valve assembly in the bore to counteract the spring force on the sliding valve of the heavy-gauge spring in the modulator when the vacuum modulator assembly is in a lower vacuum/higher pressure position. With the added spring, upshifts during acceleration will occur under low vacuum/high pressure conditions without a need to release the throttle. The invention is particularly advantageous for emergency vehicles, such as ambulances, that require rapid, yet smooth, acceleration.
    • 传输真空调制器组件具有真空调制器,其具有可与阀组件中的孔中的滑动或滑阀可移动地连接的大规模弹簧和隔膜。 液压传动液体流入变速器,优选柴油机自动变速器的流量由滑阀调节。 该改进包括添加具有在约1和2 p.s.i之间的弹簧力的螺旋弹簧。 当真空调节器组件处于较低的真空/较高压力位置时,在孔中的阀组件抵消调制器中的重型弹簧的滑阀上的弹簧力。 增加弹簧时,加速过程中会在低真空/高压条件下进行升档,无需释放油门。 本发明对于需要快速而平滑的加速的紧急车辆,例如救护车,是特别有利的。
