FLUID HANDLING APPARATUS HAVING A FLUID METERING VOLUME THEREIN

摘要

A fluid handling device of the rotary slot type is characterized by a fluid metering volume disposed in the stator of the device in close proximity to a fluid transfer passage formed in the stator. The metering volume receives a piston movable in a suction and a pumping stroke to draw fluid into the metering volume and to pump fluid therefrom. A rotary seal having the slot formed therein is received by seal rotating actuator such that a portion of a tab formed on the seal is accessible to permit removal of the seal from the rotating actuator.
