ABSTRACT:
A pair of metering pumps are fixedly supported on a mounting frame and are driven in tandem by a reciprocable thrust mechanism for driving the piston or cylinder element of the pump. The thrust mechanism is movable transversely to the reciprocating direction and is supported on a frame. Two levers have respective ends linked to the thrust mechanism and to the frame, respectively. One of the reciprocable pump elements is suspended on a respective lever whereby reciprocation of the thrust mechanism causes corresponding reciprocation of the suspended pump element. The levers are held stationary with respect to the thrust mechanism and the suspension of the reciprocable pump elements holds them stationary with respect to the mounting frame.
