摘要： Pulsation, vibration and noise of a screw compressor is caused by compressed air abruptly discharging through a discharge port in a rotor chamber during rotation of a pair of rotors. The inside opening shape of the discharge port is within two tip curved lines drawn by the pair of rotors and coincides with the two tip curved lines at least at one point when fluid starts to discharge. In one embodiment, the inside opening shape is triangular with a vertex at a point of intersection of the two tip curved lines and a base side along the discharge end face of the rotor chamber. With this, when the air compressed in the compression chamber discharges from the discharge port, the discharge opening area of the discharge port smoothly increases. This reduces the pulsation of the discharged air and thus reduces the vibration and noise of the screw compressor.
摘要翻译：螺旋式压缩机的脉动，振动和噪音是由一对转子旋转期间的压缩空气通过转子室中的排出口突然排出而引起的。排出口的内部开口形状在由一对转子拉出的两个尖端曲线内，并且至少在流体开始排出时的一个点处与两个末端曲线重合。在一个实施例中，内侧开口形状是三角形的，顶点位于两个尖端曲线的交点处和沿着转子室的排放端面的基底侧。由此，当在压缩室中压缩的空气从排出口排出时，排出口的排出口面积平滑地增大。这减少了排出的空气的脉动，从而减少了螺杆式压缩机的振动和噪音。

摘要： An improved rotary piston blower supplies an oxidant stream to a fuel cell. In one embodiment, the improved rotary piston blower includes cantilevered shafts. The improved rotary piston blower is also able to supply an oil-free oxidant stream to an electrochemical fuel cell. The improved rotary piston blower has fewer components, fewer seals, and is easier to fabricate, in comparison to conventional, prior art rotary piston blowers.

摘要： A double screw rotor assembly includes two screw rotors meshed in a bushing inside a casing. The threads of the screw rotors have a constant pitch, and define with the bushing a plurality of air chambers in the pitch. The volumes of the air chambers reduce gradually from the inlet toward the outlet due to reduced tooth height so that the outer diameter defined by the tooth tip of the thread of each screw rotor has the shape of an invertedly disposed cone. An electric driving device is controlled to move the bushing axially in the casing relative to the screw rotors in adjusting the clearance between the inside wall of the bushing and the tooth tip of the thread of each screw rotor, so as to minimize the consumption of starting power and facilitate stable running of the screw rotors, Further, a O-ring is provided at the top wall of the busing and pressed on the casing to keep an airtight status, so as to improve the working efficiency.
