Rotary group consists of cylinder block and 9 piston assemblies located in the cylinder. Both ends of
cylinder block are supported by bearings. Piston assemblies are guided by return plate and spring so they
slide smoothly on the swash plate. Valve plate is pressed against the cylinder block surface by the
mechanical pressure of spring and hydraulic pressure working on the bushing.
Between the outer diameter of the cylinder block and housing a mechanical brake for parking is mounted.
The cover section has a relief valve for cushioning and an anti-cavitation valve to prevent cavitation and
rebound damping valve for smooth stoping.
