4 FUNCTIONL DESCRIPTION - OTOR TYPE RT - RTE - RTF FUNCTIONL DESCRIPTION TIING SYSTE EFFICIENCY The outstanding performance, which is already known in our R - RE series motors, is the result of an original and patented design. The principle is to transmit the effort from the stator to the rotating shaft () by means of a pressurized column of oil () instead of the more common connecting rods, pistons, pads and pins. This oil column is contained by a telescopic cylinder () with a mechanical connection at the lips at each end which seal against the spherical surfaces () of the cylinder-heads () and the spherical surface of the rotating shaft (). These lips retain their circular cross section when stressed by the pressure so there is no alteration in the sealing geometry. The particular selection of materials and optimisation of design has minimized both the friction and the leakage. nother advantage of this design stems from the elimination of any connecting rods, the cylinder can only expand and retract linearly so there are no transverse components of the thrust. This means no oval wear on the moving parts and no side forces on the cylinder joints. consequence of this novel design as a piston motor is the significant reduction in dimensions. Especially the diameter is limitated to a value of motors with half of its capacity. Performances reached by this motor type are improved with reference to other motors of same diplacement. nother advantage stems from the geometrical arrangement of the - pistons, that results in a static balance of the motor shaft and in a great reduction of the reaction forces on the bearings with consequent large extension of their life time. The timing system is realized by means of a rotary valve () driven by the rotary valve driving shaft (8) that it is connected to the rotating shaft. The rotary valve rotates between the rotary valve plate (6) and the reaction ring (7) which are fixed with the motor's housing. This timing system is also of a patented design being pressure balanced and self compensating for thermal expansion. The motor sizes from RTE 6 to RTE are available with large timing system option that allows higher motor power performances as well as the possibility to have a throughhollow shaft (see pages, 8-9). The advantages of this type of valve coupled with a revolutionary cylinder arrangement produce a motor with extremly high values of mechanical and volumetric efficiency. The torque output is smooth even at very low speed and the motor gives a high performance starting under load. RCOe /.

6 OIL SELECTION - OTOR TYPE RT - RTE - RTF EXPLE: t a certain ambient temperature, the operating temperature in the circuit is C. In the optimum operating viscosity range (v rec ; shaded section), this corresponds to viscosity grades VG 6 or VG 68; VG 68 should be selected. IPORTNT: The drain oil temperature is influenced by pressure and speed and is usually higher than the circuit temperature or the tank temperature. t no point in the system, however, may the temperature be higher than 8 C. If the optimum conditions cannot be met due to the extreme operating parameters or high ambient temperature, we always recommend flushing the motor case in order to operate within the viscosity limits. Should it be absolutely necessary to use a viscosity beyond the recommended range, you should first contact PRKER Calzoni for confirmation. viscosity ν (mm /s) Temperature t in C Oil temperature range ν REC GENERL NOTES OPERTING VISCOSITY RNGE LIITS OF VISCOSITY RNGE CHOOSING THE TYPE OF FLUID CCORDING TO THE OPERTING TEPERTURE FILTRTION CSE DRIN PRESSURE "FP" SELS ore detailed information regarding the choice of the fluid can be requested to PRKER Calzoni. Further notes on installation and commissioning can be found on page of this data sheet. When operating with HF pressure fluids or bio-degradable pressure fluids possible limitations of the technical data must be taken into consideration, please see information sheet TCS 8, or consult PRKER Calzoni. The viscosity, quality and cleanliness of operating fluids are decisive factors in determining the reliability, performance and life-time of an hydraulic component. The maximum life-time and performance are achieved within the recommended viscosity range. For applications that go beyond this range, we recommend to contact PRKER Calzoni. ν rec. = recommended operating viscosity... mm /s This viscosity refers to the temperature of the fluid entering the motor, and at the same time to the temperature inside the motor housing (case temperature). We recommend to select the viscosity of the fluid based on the maximum operating temperature, to remain within the recommended viscosity range. To reach the value of maximum continuous power the operating viscosity should be within the recommended viscosity range of - cst. For limit conditions the following is valid: ν min.abs. = mm /s in emergency, short term ν min. = 8 mm /s for continuous operation at reduced performances ν max. = mm /s short term upon cold start The operating temperature of the motor is defined as the greater temperature between that of the incoming fluid and that of the fluid inside the motor housing (case temperature).we recommend that you choose the viscosity of the fluid based on the maximum operating temperature, to remain within the recommended viscosity range (see diagram). We recommend that the higher viscosity grade must be selected in each case. The motor life also depends on the fluid filtration. t least it must correspond to one of the following cleanliness. class 9 according to NS 68 class 6 according to E, ST, I class 8/ according to ISO/DIS 6 In order to assure a longer life a cleanliness class 8 to NS 68 is recommended, achieved with a filter of β =. In case the above mentioned classes can not be achieved, please consult us. The lower the speed and the case drain pressure, the longer the life of the shaft seal. The maximum permissible housing pressure is p max = bar If the case drain pressure is higher than bar it is possible to use a special bar shaft seal (see page, Seals, Code"F"). In case of operating conditions with high oil temperature or high ambient temperature, we recommend to use "FP" seals (see page, Seals, Code "V"). These "FP" seals should be used with HFD fluids. 6 RCOe /.

7 FLUSHING PROCEDURE - OTOR TYPE RT - RTE - RTF "" Orifice B "" Temperature t FLUSHING CIRCUIT FLUSHING PROCEDURE In order to achieve the maximum continuous performance values the flushing of the housing is necessary (see diagrams pages 8 to ). Under special conditions, in order to achieve the recommended operating viscosity of - mm /s in the motor housing, the flushing of the motor may be necessary also in the "operating area without flushing" see page 6 and the "operating diagram" page 7 to. NOTE: The oil temperature inside the motor housing is obtainable by adding C to the motor housing surface temperature, measured between two cylinders (t, see figures). FUNCTION: The flushing valve takes the flushing flow always from the low pressure line of the motor. The diameter of the orifice has to be chosen in order to supply the recommended quantity of flushing flow of l/min.

Caution: Flushing does not work until the "closed" orifice is replaced by the proper one. 7 RCOe /.
