摘要： In a pressure-responsive actuator, the inside of a case is divided into first and second air chambers by a diaphragm, and a coil spring is accommodated in the second air chamber for exerting a spring force for urging the diaphragm in a direction to decrease the volume of the first air chamber. A rod is coaxially connected at one of opposite ends to a side of a retainer mounted to a central portion of the diaphragm on the side of the first air chamber and at the other end to a tip end of an arm fixed at its base end to a driven shaft rotatable about an axis perpendicular to a plane parallel to the rod. In this pressure-responsive actuator, the case is provided with a tilt-restricting portion for restricting the tilt of the rod to a range in which the contacting of the diaphragm with the inner surface of the case can be avoided.

摘要： Cavitation is reduced in a rotary pump while the pump performance is maintained by utilizing a low-temperature fluid source already present in the pump system. The fluid from the low-temperature fluid source receives heat from the fluid flowing to the pump, thereby lowering its temperature and the saturated vapor pressure, which increases the allowable margin for a decrease in fluid pressure and reduces the occurrence of cavitation. The pump system may be used for a liquid rocket engine. The fluid velocity of the fluid directed to the pump is low before releasing heat, so there is only a slight pressure loss at the pump. Accordingly, the temperature is lowered and the occurrence of cavitation is reduced within the pump.

摘要： A pressure swing adsorption process which includes switching a plurality of adsorption columns packed with an adsorbent successively to an adsorption step, a pressure equalization step, an evacuation step, a vacuum purge step, a pressure equalization step and a repressurization step to allow a more strongly adsorbable component gas contained in a gaseous mixture to be adsorbed on the adsorbent and to separate a less strongly adsorbable component gas. The process further includes compressing the thus separated less strongly adsorbable component gas by a product gas compressor to supply it as a product gas. An adsorption column having completed the adsorption step and another adsorption column having completed the vacuum purge step are allowed to communicate to each other on product discharge sides and on raw material supply sides respectively in the pressure equalization step, to recover the product gas under gradual increase of gas flow rate on the raw material supply side and also to evacuate the adsorption column having completed the adsoroption step.
