The invention provides an integrated pump capable of providing two vacuum sources, which comprises a vacuum pump and an oil pump, the vacuum pump comprises a vacuum pump body, the vacuum pump body is provided with a vacuum pump cavity, a first gas path and a second gas path, and each of the first gas path and the second gas path is provided with a port formed in the bottom surface of the vacuum pump cavity; the first air path participates in forming a main air suction system, and the second air path participates in forming an auxiliary air suction system; the rotor and the rotary vane are installed in the vacuum pump cavity, and the volumes of the ends, sweeping the vacuum pump cavity, of the rotary vane are different when the rotor rotates by a circle from the beginning of air suction to the end of air suction of the two air suction systems. According to the technical scheme, the main air suction system can provide a vacuum source for brake assistance, and the auxiliary air suction system can provide a vacuum source for other parts of the automobile, such as an automobile designed for meeting the energy-saving and environment-friendly requirements; vacuum is provided for an EGR valve, i.e., an exhaust gas recirculation system and a turbocharged wastegate drive system, which require an additional vacuum source supply device.

    本发明提供了一种能提供两种真空源的集成泵,包括真空泵和机油泵,所述真空泵包括真空泵泵体,真空泵泵体上设有真空泵腔体、第一气路和第二气路,第一气路和第二气路各有一端口开设于真空泵腔体的底面;第一气路参与构成主吸气系统,第二气路参与构成副吸气系统;真空泵腔体内安装有转子和旋片,转子每转一圈,两吸气系统从吸气开始到吸气终了时旋片一端扫过真空泵腔体的容积大小不同。上述技术方案中的主吸气系统能够为刹车助力提供真空源,副吸气系统则为车辆其它部件提供真空源,比如为了满足节能环保要求而设计的汽车,需要额外的真空源供应装置的EGR阀即废气再循环系统以及涡轮增压废气门驱动系统提供真空。
