STRUCTURE AND FUNCTION HYDRAULIC PUMP OPERATION 1. Operation of pump Cylinder block (9) rotates together with shaft (1), and shoe (7) slides on flat surface A . When this happens, rocker cam (4) moves along cylindrical surface B , so angle between center line X of rocker cam (4) and the axial direction of cylinder block (9) changes. (Angle swash plate angle). i) Center line X of rocker swash plate angle moves as a cam in relation to shoe (7). lumes E and F this difference F - E . andthevolumeofchamber F other hand, the volume of chamber oil is sucked in (Fig. 1). ii) If center line X mes and mes 0, so the pump does suction or discharge of oil (Fig. 2).
