Radial-piston hydraulic motor and method for regulation of a radial- piston hydraulic motor

摘要

A radial-piston hydraulic motor and method for regulating a radial- piston hydraulic motor including one or more cylinder groups, each cylinder group having piston mechanisms that move radially back and forth. The piston mechanisms include a piston and a press wheel. The volume per revolution of the motor can be changed in one or more stages so that the press wheels of one or more of the piston mechanisms come out of contact with a cam ring. The hydraulic motor also includes a closing valve for closing the flow of working pressure to one or more of the piston mechanisms.
