|Title:||TWO-DIMENSIONAL PISTON OIL TRANSFER PUMP|
Disclosed is a two-dimensional piston oil transfer pump, comprising a pump housing (15), a left end cover (1), a right end cover (11), a left pump core, a right pump core, a motor coupling (2) and an intermediate coupling (9), wherein the left and right pump cores are disposed inside the pump housing (15) and are fixedly connected to the pump housing (15) by means of the limiting by the left end cover (1) and the right end cover (11); and the left and right pump cores are connected and driven by the intermediate coupling (9). Thanks to a special drive and oil circuit design, the structure optimization, simplified processing, and significant weight reduction of a pump body and a cylinder allowed for facilitation of the miniaturization of the pump.
