摘要： A hydraulic system for a motor vehicle is provided with a pump suction enhancer includes a body section defining a small chamber, a venturi tube passage exposed to the small chamber at an inner end thereof and connected to the suction port of the oil pump, and a nozzle protruding into the small chamber to face the inner end of the venturi tube passage with a space relative to the venturi tube passage in axial alignment with the same. The flow divider divides the operating oil discharged from the oil pump into a return flow to the pump suction enhancer and a supply flow which passes through a power steering device to return to an oil reservoir. The pump suction enhancer may be integrally formed with the oil reservoir or provided as a discrete component separated from the oil reservoir, oil pump and the flow divider.

摘要： A hydraulic system for a motor vehicle is provided with a pump suction enhancer for boosting the suction of operating oil into a suction port of an oil pump. The pump suction enhancer is composed of a body section for defining a small chamber, a venturi tube passage exposed to the small chamber at an inner end thereof and connected to the suction port of the oil pump, and a nozzle protruding into the small chamber to face the inner end of the venturi tube passage with a space relative to the venturi tube passage in axial alignment with the same for ejecting the operating oil returned from a flow divider into the venturi tube passage thereby to plunge the operating oil from the small chamber into the venturi tube passage. The flow divider divides the operating oil discharged from the oil pump into a return flow to the pump suction enhancer and into a supply flow which passes through a power steering device to return to an oil reservoir. In a first embodiment, the pump suction enhancer is integrally formed with the oil reservoir with the small chamber opening to a reservoir chamber defined in the oil reservoir. In a second embodiment, the pump suction enhancer is provided as a discrete component separated from the oil reservoir, oil pump and the flow divider.
摘要翻译：一种用于机动车辆的液压系统设置有用于将工作油的吸入增加到油泵的吸入口的泵吸力增强器。泵吸力增强器由用于限定小室的主体部分，在其内端暴露于小室并连接到油泵的吸入口的文丘里管通道和突出到小室中的喷嘴组成面对文丘里管通道的内端，相对于文丘里管通道的空间相对于文丘里管通道的轴向对准，用于将从分流器返回的工作油喷射到文丘里管通道中，从而将工作油从小室浸入文丘里管通道。分流器将从油泵排出的工作油分离成泵吸力增强器的回流，并进入通过动力转向装置返回到油箱的供给流。在第一实施例中，泵抽吸增强器与储油器一体地形成，其中小室通向限定在储油器中的储存室。在第二实施例中，泵抽吸增强器设置为与储油器，油泵和分流器分离的分立部件。
