Hydraulic motor 1
The high-pressure oil that flows from the main port (1) passes through the valve (2) and valve plate (3) and into the
geroler (4). The geroler (4) is formed of a stator (5), which is installed in the housing and has seven rollers on its inner
side, and a roller (6). The inner rotor has six external teeth. These teeth divide the geroler into seven internal chambers.
The rotor (6) is designed to orbit around the inside of the stator (5).
Meanwhile, the valve (2) has twelve oil holes, six of which are provided for high-pressure oil to flow into and another
six for the return oil to flow into. The valve plate (3) also has seven oil holes, which are connected to the seven chambers
in the gerolor (4). The circuit to the gerolor (4) is then opened when the seven oil holes in the valve plate (3) are con-
nected to some of the twelve oil holes in the valve.
As thus described, the planetary motion of the rotor (6) in the gerolor (4) is initiated by the hydraulic pressure. Of the
planetary motion present in the system, only the rotating motion of the rotor itself is extracted from the drive shaft (7)
and transmitted to the shaft (8).
The rotating motion of the rotor (6) is transmitted to the valve through the valve drive shaft (9).
In this way, the oil holes in the valve (2) connected to the oil holes in the valve plate (3) are shifted in turns whenever
the valve (2) rotates. This allows the high-pressure oil that entered the gerolor (4) to flow into the different chambers in
turns. As a result, the motor is able to continuously rotate.
