The invention provides a hydraulic system and an aviation catering vehicle. The aviation catering vehicle comprises an engine. The hydraulic system comprises a working hydraulic system, a power-assisted steering hydraulic system, an oil tank, a power-assisted steering pump and a multi-way valve. The oil tank is used for storing hydraulic oil. The power-assisted steering pump is provided with an oil inlet and an oil outlet and is driven by the engine, and the oil inlet is connected to the oil tank through an oil way. The multi-way valve is provided with an inlet and two outlets, the inlet is connected to the oil outlet of the power-assisted steering pump through an oil way, and the two outlets are connected to the working hydraulic system and the power-assisted steering hydraulic system through oil ways respectively. The hydraulic system is configured to selectively communicate with one of the two outlets through the multi-way valve, and the power-assisted steering pump selectively supplies oil to the working hydraulic system or the power-assisted steering hydraulic system. According to the hydraulic system, a power takeoff and a hydraulic pump are omitted, the failure rate of the system during working is decreased, meanwhile, the production and manufacturing cost of the whole vehicle can be reduced, and good technical and economic benefits can be achieved.

    本发明提出一种液压系统及航空食品车,航空食品车包含发动机,液压系统包含工作液压系统、助力转向液压系统、油箱、助力转向泵以及多通阀。油箱用以储存液压油。助力转向泵具有进油口和出油口并由发动机驱动,进油口通过油路连接于油箱。多通阀具有一个进口和两个出口,进口通过油路连接于助力转向泵的出油口,两个出口分别通过油路连接于工作液压系统和助力转向液压系统。液压系统被配置为通过多通阀选择性地连通两个出口的其中之一,供助力转向泵选择性地向工作液压系统或助力转向液压系统供油。本发明提出的液压系统减少了取力器和液压泵的使用,降低了系统工作时的故障率,同时可降低整车的生产制作成本,可实现较佳的技术经济效益。
