The eccentric cam radial move in the variable motors type MRV/MRVE/MRVA is controlled by means of a
counter check valve (11) located inside the rotating shaft. This valve pilots the movement of the
displacement change system cylinders (12): with this solution it is possible to obtain whatever value of
displacement within the maximum range allowed by means of a continuous variation of the position of the
eccentric cam (2).
The usage of Parker Calzoni motors is made very flexible by means of electronic and hydraulic regulation
circuits; moreover, these solutions lead to efficiency increase and performances improvement of the machine
the motors are installed on.
Thanks to these design peculiarities, Parker Calzoni motors grant high mechanical and volumetric efficiency
values, even at very low speed and high operating pressure, as well as in starting torque condition; these
performances do not worsen during the motor service life, granting the reliability for which this motor brand
is well known.
According to the application’s request, the motor can be provided in different configurations. To widen the
motors’ flexibility PARKER CALZONI provides a series of accessories and options (for all information
concerning the technical and dimensions characteristics pls. refer to the correspondent “technical
catalogue“).
