Abstract: An integrated apparatus for precisely and synchronously controlling amounts of discharged hydraulic oil and fluid using a motor, includes a housing. A movable dual-piston extractor, a motor and a plunger pump are configured in the housing and sequentially connected. A hydraulic pipeline and a fluid pipeline are connected with the housing to control flows of hydraulic oil and a fluid. A specified amount of fluid sample can be precisely extracted by precisely controlling, according to a control circuit, the number of rotations of the motor, which is indirectly reflected to a travel distance of the lead screw. A motor indirectly drives a lead screw, a nut and a piston to move linearly along a hydraulic chamber through mechanisms including a transmission shaft, and according to a position where the transmission shaft of the motor rotates, the displacement distance of the piston can be measured precisely.
