FIELD: engines and pumps. ^ SUBSTANCE: axial piston pump of variable capacity includes housing, shaft installed in bearings, block of cylinders with pistons, craddle located in bearings, check valves located in pump cover, and make-up pump with safety valve. To it there introduced is shaped collet installed on craddle and position sensor of craddle, which is installed on housing so that the possibility of interaction of its stock with shaped surface of collet is provided. Proportional electro-driven hydraulic valve is installed on the housing with possibility of interaction with cylinders of control mechanism. ^ EFFECT: enlarging operating capacities of pump owing to implementing the electrohydraulic proportional control in it and improving its dynamic characteristics. ^ 2 dwg |
