Hydraulic Motor 液压马达维修手册--CMM-27-50-06， CMM-27-50-08
This motor is constant displacement, bent-axis, piston type unit. The direction of rotation iscontrolled by fluid flow through the unit by reversing fluid flow, the direction of motorrotation can be reversed. The motor may be operated in either direction continuously,intermittently or stalled without damage at rated pressures and in a system incorporating proper overload pressure relief. Motor mounting position is unrestricted, except that the case drain line must be connected directly to the hydraulic reservoir in such a manner that the motor housing remains filled with hydraulic fluid. Internal motor parts depend on this fluid in the housing for lubrication.
