2 AXIAL PISTON PUMPS V Series AXIAL PISTON PUMP FEATURES The latest design in the proven V Series, medium pressure, open loop system variable displacement pump has been developed for the mobile and industrial market where low reliability are all considered essential. options allow each of the V Series units to be easily matched to any application. Specially designed for the noise-critical application, its rigid and compact structure reduces air borne noise emissions. All noise reduction features of the V Series provide a typical reduction of 6dB(A) compared with conventional designs. Technical Characteristics Ma.

3 FUNCTIONAL DESCRIPTION OF REGULATOR Control Type Hydraulic Symbol Control Curve HL - Load sensing compensator control 1 - The pump outlet can be controlled by the setting pressure value of control valve. An ideal energy conservation system can be configurated by combining the proportional directional control. - When setting pressure value, flow is changed depending on the throttle valve. The sensing flow feedback function can reach to low oil heat generation and saving energy. HJ - Load sensing & proportional electrohydraulic pilot relief valve 1-The same function of "HL" and proportional function added. - Supplied with proportional electro-hydraulic pilot relief valve can reach to power saving. HK- Proportional electro-hydraulic load sensing control 1 - This control type supply the system pressure and flow depending on the proportional pressure and flow, voltage and load value to save energy. When in waiting circle, the outlet displacement and horse-power loss are close to zero. When pressure reaches to preset value, the flow decrease to the min. and the pressure is constant to reach low oil heat generation and energy loss. - HK control type can save -% energy compared to vane and gear pump + PQ valve. It is an energy saving and environmental design. HQ - Load sensing proportional flow control 1 - The same function of "HL" control type and proportional flow function added. - The proportional flow control allows the adjustment of the pump output flow with an electric input signal. Pump flow rate are controlled proportionally to the input current to the control device on the pump and the input current is regulated by the specific amplifier. Pag. 11
