Method of metering a fluid using a multi-mode differential fluid displacement pump
First Claim
1. A method of metering a measured amount of a first fluid into a measured amount of a second fluid comprising,confining a fluid within a first chamber of defined volume,mechanically moving a first displacement solid into said defined chamber volume to displace a first measured amount of said confined fluid therefrom,mechanically moving a second displacement solid into said defined chamber volume to displace a second volume of said confined fluid therefrom different from said first volume whereupon said first and second volumes can be mixed in predetermined proportion.

Abstract
A measured amount of a first fluid is metered into a measured amount of a second fluid by a method where a fluid is confined within a first chamber and a plunger of predetermined volume is mechanically moved into the chamber to displace a first measured amount of fluid after which a second plunger is mechanically moved into a defined volume of the chamber to displace a second volume of fluid therefrom different from the first volume whereupon the first and second volumes can be mixed in predetermined proportions.
