油压泵、油压泵单元、油压驱动设备
摘要：
本发明提供一种不单独设置减压阀即能防止高压下损坏的油压泵。壳体1a设有在与油压泵1的回转轴1d垂直的面上分割的本体侧和盖侧，该盖侧壳体1b用弹簧1m以与泵允许油压对应的预定压力油密地对接在本体侧壳体1c上。
摘要（英）：

This invention provides an oil pressure pump, which can prevent damages under high pressure without individually installing a pressure reducing valve. The casing 1a comprises a body side and a cover side divided on the surface vertical to the revolving shaft 1d of the oil pressure pump 1; the cover side casing 1b is oil sealed and butt jointed with the body side casing 1c using a spring 1m at thepredetermined pressure corresponding to the allowed oil pressure of the pump.
