Abstract
The utility model discloses an integral type multipath reversing valve body of a mini loader. The integral type multipath reversing valve body comprises an integrally casted valve body, where a first valve hole, a second valve hole and a third valve hole are arranged. A plurality of valve chambers are respectively arranged in the first valve hole, the second valve hole and the third valve hole, and the quantity of the valve chambers in the first valve hole is identical to that in the second valve hole. The first valve hole, the second valve hole and the third valve hole are communicated with one another. The valve body is casted in one time, and oil channels are reasonable in design, great in flow and stable for control. Valve holes of the oil channels are communicated with one another, thereby realizing series-parallel oil paths in the valve body.
