www.atos.com Table A60/E Axial piston pumps type PVP variable displacement, by a full line of mechanical controls PVPL4046 PVP are variable displacement axial piston pumps for high pressure operation, with low noise level, suitable for hydraulic oils or synthetic fluids having symilar lubricating characteristics. The actual displacement is dependent on the lenght of stroke of the pumping pistons. This lenght of stroke is determined by the position of the swashing plate that is achieved by two servo pistons with differential areas, against a spring. The rotating barrel forces the pistons in a circular path in and out of the barrel and fluid displacement takes place. Typical section on side shows version L with manual pressure compensator and flow regulation. The available hydraulic controls are shown in sections. The wide range of electrohydraulic proportional controls is shown in tab. A70. SAE J744 mounting flange and shaft (see note ). Max displacement: 29467388 cm 3 /rev. Max pressure: 280 bar working 350 bar peak.

8 HYDRAULI AND ELETROHYDRAULI ONTROLS Hysteresis and pressure increasing; max 4 bar Manual pressure compensator The pump displacement decreases when the line pressure approaches the setting pressure of the compensator. The pump supplies only the fluid required by the system. Pressure may be steplessly adjusted at the pilot valve. ompensator setting range: 20 350 bar (35 bar for 090) ompensator standard setting: 280 bar (250 bar for 090) Flow [l/min] H Manual pressure compensator with venting As plus venting function, when a long unloading time is required and heat generation and noise have to be kept at lowest level. ompensator setting range: 20 350 bar (35 bar for 090) ompensator standard setting: 280 bar (250 bar for 090) Flow [l/min] Hysteresis and pressure increasing; max 4 bar R Remote pressure compensator As, but with remote setting of the compensator by means of a pressure relief valve on the piloting line X. This version can be obtained from version L using a blind plug UNI 5923 M4x2 in pos.l and a restrictor M4 drilled ø 0,75 mm in pos.. ompensator setting range: 20 350 bar (35 bar for 090) ompensator standard setting: 280 bar (250 bar for 090) Flow [l/min] Hysteresis and pressure increasing; max 4 bar not supplied L Load sensing The pump displacement is automatically adjusted to maintain a constant (load indipendent) pressure drop across an external throttle. hanging the throttle regulation, the pump flow is consequently adjusted. Load sensing control always incorporates an hydraulic compensator to limit the maximum pressure. ompensator setting range: 20 350 bar (35 bar for 090) ompensator standard setting: 280 bar (250 bar for 090) Differential pressure setting range: 0 40 bar Differential pressure standard setting: 4 bar Flow [l/min] Hysteresis and pressure increasing; max 4 bar not supplied LW onstant power In order to achieve a constant drive torque with varying operating pressure. The swashing angle and therefore the outlet flow is varied so that the product of flow and pressure remains constant. For the best regulation, minimum working pressure is 80 bar. While selecting LW control, the required value of power must be communicated with the order (ex. 0 kw at 450 rpm). Flow [% of max] Minimum power curve 300 Maximum power curve Theoretical power curve
