摘要：
本发明公开了一种液压驱动式无间歇增压装置，包括液压泵、溢流阀、油箱、单杆活塞式液压缸一、单杆活塞式液压缸二和双杆活塞式液压缸；所述单杆活塞式液压缸一的无杆腔和所述双杆活塞式液压缸的左腔均与电磁换向阀的第一工作端口连通，所述单杆活塞式液压缸二的无杆腔和所述双杆活塞式液压缸的右腔均与电磁换向阀的第二工作端口连通，所述单杆活塞式液压缸一的有杆腔、所述单杆活塞式液压缸二的有杆腔以及电磁换向阀的第四工作端口均与油箱连通，所述电磁换向阀的第三工作端口与液压泵的出油口连通。本发明具有以下特点：设计合理可无间歇提供高压油液，减少设备投入，采用机电液一体化设计，智能化程度高。
摘要（英）：

The invention discloses a hydraulic driven type non-intermittent supercharging device, comprising a hydraulic pump, an overflow valve, a fuel tank, a first single-rod piston hydraulic cylinder, a second single-rod piston hydraulic cylinder, and a double-rod piston hydraulic cylinder. The rodless cavity of the first single-rod piston hydraulic cylinder and the left cavity of the double-rod piston hydraulic cylinder are communicated with the first work port of a magnetic directional valve. The rodless cavity of the second single-rod piston hydraulic cylinder and the right cavity of the double-rod piston hydraulic cylinder are communicated with the second work port of the magnetic directional valve. The rod cavity of the first single-rod piston hydraulic cylinder, the rod cavity of the second single-rod piston hydraulic cylinder, and the fourth work port of the magnetic directional valve are communicated with the fuel tank. The third work port of the magnetic directional valve is communicated with the oil outlet of the hydraulic pump. The device is characterized by rational design, non-intermittent high-pressure oil liquid providing, reduced equipment investment, mechanics-electronics-hydraulics integrated design, high intelligent degree.
