The invention discloses a double-swash-plate plunger type variable pump. The double-swash-plate plunger type variable pump comprises an outer shell, a left end cover, a right end cover, a stator core, a motor winding, a rotor, a cylinder body, multiple plungers, two swash plate assemblies and multiple distribution devices. Each swash plate assembly comprises a swash plate, multiple piston shoes and a return plate. The two swatch plates are the left swatch plate and the right swatch plate respectively, the left swatch plate is fixedly installed on the left end cover, the right swatch plate is rotationally installed on the cylinder body or the right end cover and can rotate around the central axis of the cylinder body, and the right swatch plate is connected with a variable adjusting mechanism used for driving the right swatch plate to rotate so as to change the relative position of the right swatch plate and the left swatch plate. The double-swash-plate plunger type variable pump has the advantages of being small in size, large in flow, low in noise, small in leakage amount and the like, can achieve large-range stepless adjustment of displacement of the variable pump, effectively reduces energy loss, improves the system efficiency, effectively reduces pollution degree and system faults of a hydraulic system, and prolongs the service life of the hydraulic system.
