ABSTRACT:
A valveless metering pump includes a simultaneously reciprocating and rotating piston. The pump head includes radially spaced coplanar ports for drawing and dispensing fluids as the piston rotates sequentially past the ports. The reciprocating stroke of the piston is controlled by adjusting the axis of the piston relative to the drive axis. The pump is designed so that the angular relationship of the ports also can be adjusted relative to the piston to balance the output at the sequential ports. The plurality of adjustments provide a valveless, positive displacement metering pump which is reliable and dependable for dispensing precise volumes of fluid through a plurality of outlet ports.
