Abstract: This invention relates to ununiform rotary transmission and control method to improve compression efficiency and pulsation rate of object fluid by changing the velocity of suction and compression strokes in pump and compressor and improve suction efficiency and combustion efficiency of internal combustion engine by changing compression (exhaust) and explosion (suction) time. In compressor and pump, the rotation angle of driving rod during compression is made larger than that during suction, thereby reducing maximum torque of driving axle during compression and consequently getting desired result with a driving unit of small capacity. In this way, this invention improves overall efficiency and pulsation rate of object fluid, and provides internal combustion engine with conditions close to complete combustion by elongating suction and explosion time compared with compression and exhaust time.

Abstract translation: 本发明涉及通过改变泵和压缩机中的吸入和压缩冲程的速度来提高物体流体的压缩效率和脉动速率的不均匀旋转传动和控制方法，通过改变压缩（排气）来提高内燃机的吸入效率和燃烧效率， 和爆炸（吸力）时间。 在压缩机和泵中，压缩期间驱动杆的旋转角度大于抽吸时的旋转角度，从而降低了压缩过程中驱动轴的最大扭矩，从而使得具有小容量的驱动单元得到期望的结果。 以这种方式，本发明提高了对象流体的总体效率和脉动率，并且通过与压缩和排气时间相比延长抽吸和爆炸时间来提供具有接近完全燃烧的状态的内燃机。

Abstract: A fluid dispenser with a fluid pump for dispensing fluid on movement of an actuator, and an air pump for delivering a stream of air through at least one sound generator on movement of the actuator. The sound generator produces at least two sounds as the actuator is moved from a first position to a second position, with each sound produced in a different time period during a cycle of operation, or differing from the other sound in respect of one or more detectable sound characteristics, such as duration, frequency, temporal alignment, amplitude, and/or timbre. The time period of each sound is a function of the relative location of the actuator between the first and second positions.
