Proportional pumping apparatus

Proportioning apparatus comprising:

• a first container of a first liquid and a second container of a second liquid;
• first pump means for receiving the first liquid from the first container, said first pump means having a first movable pumping member;
• second pump means for receiving the second liquid from the second container, said second pump means having a second movable pumping member, the first pumping member being movable in a first stroke and the second pumping member being movable in a second stroke;
• a motor connected to the first pumping member for moving same in said first stroke;
• a master hydraulic cylinder connected to the motor, and a piston disposed in the master hydraulic cylinder so as to be actuated in a driving motion according to the motion of the first pumping member;
• a slave hydraulic cylinder, and a piston in the slave hydraulic cylinder connected to the second pumping member so as to be movable therewith;
• conduit means including hydraulic fluid connecting the master hydraulic cylinder and the slave hydraulic cylinder such that the piston of the slave hydraulic cylinder is moved according to the motion of the piston in the master hydraulic cylinder;
• and
• mixer means for receiving the first liquid from the first container and the second liquid from the second container as the motor is actuated to simultaneously remove the first liquid from the container of said first liquid and the second liquid from the container of said second liquid.
