Numerical analysis of pressure distribution of oil film on the valve plate in variable height gap of an axial piston pump is concerned. The analysis employs the finite element method. For determination of oil pressure variations in the gap the Reynolds equation, commonly applied in the theory of lubrication by Pasynkov, was applied. The equation was solved numerically with the use of self-developed program based on finite element method. In order to obtain high accuracy of the results an adaptive mesh refinement based on residual esthnations of solution errors was applied. The calculation results were represented as dependent on the geometric and working parameters of the pump.
