Embodiment

Following the utility model will combine the embodiment in the accompanying drawing to further describe:

Comprise water supply connector 1, stator 2, first baffle plate 3, rotor 4, housing 5, pressure gauge 6, first axle sleeve 7, second axle sleeve 8, main shaft 9, bearing 10, end cap 11, shifting slide gear 12, second baffle 13, bearing 14, first setting sleeve 15, declutch shift shaft 16, shift fork 17, shifting block 18, second setting sleeve 19, locating stud 20, handle set 21, handle 22, backwater valve 23

Water supply connector 1 is installed on the stator 2, and stator is fixed, and is welded with the blade of same angle on its internal surface, and stator 2 is through being bolted on the housing 5.Pressure gauge 6 is installed in the upper end of housing 5, can show hydraulic pressure.Backwater valve 23 is installed in the lower end of housing 5, and backwater valve 23 is adjustable, can control the speed that discharges water through opening and closing size, further the size of control brake power.
