Hydraulic piston Pump A6V

Features:

The CA6V is a variable displacement motor, with axial piston rotary group, of bent axis design, for hydrostatic drives in open and closed circuits.Wide control range for hydrostatic drives Cost saving through elimination of gearbox Compact, low unit power Low inertia Good carting characteristics

Specifications:

LY-A6V Variable Displacement Pump LY-A6V

DA Hydraulic control, Speed related.

Speed related hydraulic control is used exclusively for transmission drive in conjunction with variable pump CA4VDA.

Assembly Design:Assembly type 2

Start of control:

Pilot pressure:dependent at Vgmax to VgminHigh Pressure:dependent at Vgmin to Vgmax

Start pilot at Vgmax(max torque)

The pilot pressure which is determined by the variable pump CA4V (increasing speed of prime mover=increasing speed of pump=increasing pilot pressure)is directed to port X₁ or X₂

dependent on the motor capacity(lower torque,high speed).

Should the operating pressure rise above the set pressure value at the regulator,the variable motor swivels to a higher

Capacity(higher torque,lower speed)

Pilot pressure and high pressure remain in a fixed relationship,Pst/ph=3/100,this means that 0.3 MPa variation in pilot pressure(rise or fall) gives a pressure rise or fall of 10 MPa in operating pressure.

When designing a drive with a DA control,the technical date of the variable pump type CA4V.DA must be considered
