Abstract of
EP2623782 (A2)
|
The present invention relates to a fluid metering system comprising: a cylindrical rotor having a channel completely through a diameter of the rotor with opposing openings at each end of the channel configured to allow a fluid to flow within the channel, the rotor configured and arranged to receive a torque for rotation; a substantially rectangular piston disposed within the channel, wherein the piston includes a pivot shaft with shaft ends held by the rotor, wherein the piston is configured and arranged to pivot between a first position and a second position within the channel of the rotor;; and a chamber housing having an interior configured and arranged to receive the rotor, the chamber housing further having first and second lateral openings configured and arranged to allow flow of a fluid through the interior during rotation of the rotor within the chamber as the piston pivots within the rotor channel between the first and the second positions.
