STRUCTURE AND FUNCTION HYDRAULIC PUMP 2. Control of discharge amount If swash plate angle becomes larger, the difference between volumes E and F becomes larger and discharge amount Q increases. Swash plate angle is changed by control piston (5). crease. This screw should be adjusted when the machine doesn’t travel straight or machine maximum speed is little bit wrong. Screw B is the fine adjuster of neutral position of control piston (5). That adjust prevent machine from creep.
